Aqua Voice vs Wispr Flow: Which One Wins in 2026?
The short answer
- Aqua Voice wins on technical vocabulary. Its Avalon model is tuned for jargon and its custom dictionary lets you fix the words it still gets wrong, which is why people dictating code and proper nouns pick it.
- Wispr Flow wins on messy speech and free tier. Its cleanup pass does more editorial work, and its free plan is 2,000 words every week forever against Aqua's 1,000 words once, for the life of the account.
- The price gap is smaller than advertised. Aqua's headline $8 is the annual rate ($96 up front); month to month it is $10 against Wispr Flow's $15. And Realtime Mode, the streaming text everyone watches in the demos, is on the $24 Max plan, not the $8 one.
- Both were Mac apps first, and neither runs offline. Wispr Flow's Notetaker is still Mac-only, so a Windows buyer pays full price for less. That gap is why BlabbyAI belongs in the test: Windows-native from day one, $8.49/month with no annual commitment, free tier with no card.
- The deciding question is what your speech looks like. Technical and precise points to Aqua. Conversational and messy points to Wispr. Windows-first and price-sensitive points somewhere else entirely.

System-wide on Ctrl+Space, custom modes you write in plain English, and a free tier that resets weekly with no card. Twenty minutes is all the comparison takes.
Side by side
Every price below was read from the vendor's own pricing page in August 2026 rather than copied from another comparison. That matters more in this pairing than in most, because the number repeated everywhere, $8 against $15, is not a like-for-like comparison and it flatters one side by about 20%.
| Tool | Price | Free tier | Streaming text | Platforms |
|---|---|---|---|---|
 Aqua Voice | $8/mo annually ($96), $10 monthly | 1,000 words, once, for the life of the account | Yes, on Max at $24/mo | Mac, Windows, iOS |
 Wispr Flow | $15/mo, $12 billed annually | 2,000 words weekly, ongoing | No, text arrives after you stop | Mac, Windows, iOS, Android |
 BlabbyAI | $8.49/mo, no annual lock-in | 60 credits weekly, no card | No, text arrives after you stop | Windows, Chrome, Linux |
$96, not $8
Aqua Voice Pro's advertised $8 is the annual rate, charged as one payment of $96. Month to month it is $10.
$24 for the demo
Realtime Mode, the streaming text in every Aqua demo video, sits on Max at $24 a month. Not on the $8 plan.
1,000 words, forever
Aqua's free tier is 1,000 words for the lifetime of the account. Wispr Flow gives 2,000 every week.
Aqua Voice: the precise one
Aqua Voice's pitch is speed and precision, and on technical vocabulary the precision half is real. It runs its own model, called Avalon, rather than a general-purpose speech model, and it is tuned for the category of words that make ordinary dictation tools infuriating: library names, product names, medical and legal terms, surnames, anything that is a real word to you and a nonsense string to a model trained on conversational English.
The lever that matters more than the model, though, is the custom dictionary. When Avalon still gets a term wrong, you add it and it stops getting it wrong. That is a mundane feature that turns out to decide daily satisfaction, because dictation frustration is rarely about the average error rate. It is about the same six words failing every single day.

Alongside the dictionary sit Custom Instructions, which are per-context rules about how your speech should be written down: all lowercase in a chat app, full sentences in email, never start a sentence with "And". This is the same idea most of the category has arrived at from different directions, and Aqua's version is well made.
Read the pricing page before you compare the price
Aqua Voice is quoted as an $8 tool almost everywhere, including inside Google's own AI Overview for this comparison. From the vendor's pricing page in August 2026: Pro is $8 a month billed annually, which is $96 charged in one payment, or $10 if you pay monthly. Max is $24 a month billed annually ($288) or $30 monthly. Teams of 2 to 9 are $12 per user. Students get 70% off with a school email, which takes Pro to $2.40. The figure most individuals actually pay is $96 once or $10 a month, and neither of those is $8.
The other thing worth knowing before you pick Aqua on price is what the free tier is. It is 1,000 words for the lifetime of the account, not per month and not per week. That is enough to decide whether you like the feel of it and not much more, so treat it as a demo rather than a tier you could sit on. Wispr Flow's free plan is a genuinely different proposition, and BlabbyAI's 60 credits weekly with no card is closer to Wispr's shape than to Aqua's.
Wispr Flow: the polished one
Wispr Flow is doing something structurally different, and the difference is easiest to see if you think about when the work happens. Aqua streams text as you speak. Wispr waits for you to finish, then runs a cleanup pass and pastes the result. The wait is one to three seconds. What you get back is a paragraph rather than a transcript.

That trade is the whole product. If you speak in clean, deliberate sentences, the pause buys you very little and Aqua's immediacy feels better. If you think out loud, restart sentences, trail off and pick the thought back up three words later, the pause is doing substantial work and what lands is noticeably better than what you actually said. Most people are further toward the second description than they believe, which is the honest reason Wispr Flow has the reputation it has.
Its free tier is the most generous ongoing one in this comparison: 2,000 words per week on desktop, every week, indefinitely. For light dictation that is a usable permanent allowance, not an evaluation sample, and it is a meaningfully different offer from Aqua's one-time 1,000.
Two things to weigh against it. It is $15 per user per month, or $12 billed annually, the highest price of the three tools here. And its Notetaker meeting feature is Mac-only, with Windows listed as coming, which means a Windows buyer pays the same $15 for a smaller product. Neither is disqualifying. Both are worth knowing before the card comes out.
Every tier on both sides
Laid out in full, because the two pricing pages are structured differently enough that a single headline number cannot compare them fairly. Annual columns are what you pay per month when you commit to a year up front.
| Plan | Monthly | Annual | What it gets you |
|---|---|---|---|
| Aqua Voice Starter | Free | 1,000 words total, not monthly | An evaluation sample. Two long emails will spend it. |
| Aqua Voice Pro | $10 / mo | $8 / mo ($96 a year) | Unlimited words, Custom Instructions, Custom Dictionary. No Realtime Mode. |
| Aqua Voice Max | $30 / mo | $24 / mo ($288 a year) | Adds Realtime Mode, the "Send it" command and early access. |
| Wispr Flow Free | Free | 2,000 words weekly, ongoing | Resets every week indefinitely, so it stays usable. |
| Wispr Flow Pro | $15 / user / mo | $12 / user / mo ($144 a year) | Unlimited dictation. Notetaker is Mac-only. |
| Wispr Flow Growth | from $23 / user / mo | from $18 / user / mo | Team administration on top of Pro. |
Read that table and the popular framing falls apart. Aqua Voice is cheaper than Wispr Flow, but the fair monthly comparison is $10 against $15 and the fair annual comparison is $96 against $144. That is a real saving of about $48 a year, not the near-halving the headline suggests. And if the feature you actually want from Aqua is Realtime Mode, you are comparing $288 a year against $144, at which point Aqua is the expensive one by a factor of two.
For scale on the same axis: BlabbyAI is $8.49 a month with no annual commitment, which is $101.88 across a year paid monthly, against $96 for Aqua Pro paid entirely up front and $180 for Wispr Flow paid monthly. The three sit closer together than the marketing implies, and the thing that separates them is not price.
Streaming versus waiting, and why it is the real difference
This is the one genuine architectural split between the two products, and it deserves more than a checkbox, because it changes how dictating feels rather than what the output score is.
Streaming (Aqua Voice, on Max)
Words appear as you say them. You can see a mistake land and correct course mid-sentence, which suits people who dictate the way they type: watching the screen, adjusting as they go. The cost is that what you see is closer to what you actually said, filler words included, so the tidying is your job.
Waiting (Wispr Flow, BlabbyAI)
Nothing appears until you stop, then a finished paragraph arrives at once. You speak without watching, which is faster and less distracting once you trust it. The cost is the one to three second pause and the fact that you cannot steer a sentence that is already going wrong.
Neither is better. They suit different people, and the way to find out which one you are is to notice whether you look at the screen while you talk. If you do, streaming will feel right and you should price in Aqua's $24 Max plan rather than the $8 one. If you close your eyes and think, waiting is better and Wispr Flow or a cheaper tool doing the same thing will serve you.
Which one to pick, by what you actually do
You dictate code, library names and jargon all day
Aqua Voice. The Avalon model plus a dictionary you extend yourself is the strongest answer to technical vocabulary between these two.
You ramble, restart sentences, and want clean prose out
Wispr Flow. Its cleanup pass does the most editorial work of any tool here, which is exactly what you are paying the extra $5 a month for.
You want to watch words appear as you speak
Aqua Voice, but on Max at $24 a month. It is not on the $8 plan, and at $24 it is no longer the cheaper of the two.
You want a free tier you can actually keep using
Wispr Flow at 2,000 words weekly. Aqua Voice gives 1,000 words once, for the life of the account, which is a sample rather than a tier.
You are on Windows and want an app built for Windows
Neither was. Both started on Mac. BlabbyAI is Windows-native from day one at $8.49 a month, which is why it belongs in this test.
You need it on a locked-down work laptop
Neither desktop app will install without admin rights. A Chrome extension will, which is often the only route on a managed machine.
You need dictation with no internet connection
Neither. Both are cloud-only, so this cannot separate them. Superwhisper runs models locally if that is a hard requirement.
You want to write your own rules for how speech is rewritten
Aqua has Custom Instructions, Wispr has personalization settings. BlabbyAI goes furthest: a mode is a plain-English instruction you author.
What does not differ, and why most comparisons overstate it
A lot of ink gets spilled on differences that will not affect your day. Worth knowing so you can discount them when you read the next comparison:
- Raw accuracy on ordinary speech. Both run current-generation models. On clear speech in a quiet room you will struggle to attribute an error to the tool rather than to your microphone or the room you are sitting in.
- Published accuracy percentages. Ignore them entirely, from both vendors and from the third-party pages quoting figures like 98.5% against 96.1%. Nobody publishing those numbers tested them on your voice, your accent or your vocabulary.
- App coverage. Both type into whatever field has your cursor. Any claim that one reaches more applications than the other is describing a separate feature, usually meeting notes.
- Offline capability. Neither has any. Both are cloud-only, so this cannot separate them, and if it matters to you neither is your tool.
- Setup difficulty. Both are a download, a microphone permission and a shortcut. Neither needs the voice training that older dictation software demanded.
The test that actually settles it
All three have a free tier, so run the same trial on each: dictate fifty of your own real sentences, the ones you would genuinely send or commit, and count how many corrections you make afterwards. That number is the only accuracy figure that describes your microphone, your voice and your vocabulary. It takes about twenty minutes per tool and it beats every published benchmark and every roundup, including this one. One caution: Aqua's 1,000 lifetime words will be close to spent by the end of a fifty-sentence run, so do that test last.
The gap both of them leave on Windows
Every comparison of these two, including the ones ranking above this page, treats Windows as a checkbox. Both tools list it, so both get a tick, and the conversation moves on. The detail underneath the tick is worth a paragraph, because it is where a Windows buyer loses money.
Aqua Voice and Wispr Flow are both Mac products that reached Windows later. Wispr Flow has the wider spread on paper, Mac, Windows, iPhone and Android, but its Notetaker feature and the capabilities hanging off it remain Mac-only, so the Windows subscriber pays $15 for a product with fewer features than the one being reviewed. Aqua Voice covers Mac, Windows and iPhone, with no Android build at all. Neither company is doing anything wrong here. They built where their users were. But if Windows is the machine you actually work on, you are the secondary audience for both of them.
That is the specific reason BlabbyAI belongs in this comparison rather than as a footnote to it. It was built for Windows from the first version, runs system-wide on Ctrl+Space into any application with a text field, keeps its History of past recordings on your own machine, and costs $8.49 a month with no year up front. Where Aqua gives you Custom Instructions and Wispr gives you personalization settings, BlabbyAI's custom modes are free-form instructions you write in plain English, so "rewrite this as a short formal email" or "keep code identifiers exactly as I say them" are things you can simply type rather than hope the vendor shipped.
If your machine is locked down by an employer and you cannot install an executable at all, neither desktop app is an option and the BlabbyAI Chrome extension is the shape that will actually run: no download, no admin rights, and it dictates into Gmail, Google Docs, Notion, Slack and anything else in the browser.
Frequently asked questions
What is the difference between Aqua Voice and Wispr Flow?
The headline difference is what happens between you speaking and the text appearing. Aqua Voice streams words onto the screen as you talk, with its own Avalon model tuned for technical vocabulary and a custom dictionary you can extend. Wispr Flow waits until you stop, runs a cleanup pass in the cloud, and pastes a finished, punctuated paragraph. The second difference is money: Wispr Flow Pro is $15 a month, Aqua Voice Pro advertises $8 a month but that is the annual rate, so the real monthly figure is $10. Both are cloud tools, both type into any application, and on ordinary clear speech in a quiet room the accuracy gap between them is smaller than either vendor implies.
Is Aqua Voice cheaper than Wispr Flow?
Yes, but by less than the advertised numbers suggest. The comparison people repeat is $8 against $15, which makes Aqua look roughly half the price. Read both pricing pages and the picture changes: Aqua Voice Pro is $8 a month only if you pay $96 for a year up front, and month to month it is $10. Wispr Flow Pro is $15 monthly or $12 billed annually. So the fair monthly-to-monthly comparison is $10 against $15, and the fair annual-to-annual comparison is $96 against $144. Aqua is genuinely cheaper either way, just not by the margin the headline implies. For a third data point, BlabbyAI is $8.49 a month with no annual commitment at all.
Which is more accurate, Aqua Voice or Wispr Flow?
On general dictation, close enough that your microphone matters more than your choice of app. Aqua Voice has the stronger claim on technical vocabulary, because the Avalon model is tuned for it and the custom dictionary lets you correct the words it still gets wrong, which is why developers dictating variable names tend to prefer it. Wispr Flow is stronger at turning genuinely messy conversational speech into clean prose, because its cleanup pass is doing more editorial work. Ignore the published accuracy percentages from both sides. They are measured under conditions that flatter whoever ran the benchmark, and none of them describes your room, your accent or your vocabulary.
Does Aqua Voice or Wispr Flow work better on Windows?
Both run on Windows and both were built for Mac first, which is the part most comparisons of these two skip. Wispr Flow has the wider platform spread, covering Mac, Windows, iPhone and Android, but its Notetaker meeting feature is Mac-only, so a Windows buyer pays the same $15 for a smaller product. Aqua Voice covers Mac, Windows and iPhone with no Android build. If Windows is your only machine and you want an app designed for it rather than ported to it, that is the gap in this comparison, and it is why BlabbyAI is worth adding to the shortlist: Windows-native from the start, $8.49 a month, system-wide on Ctrl+Space.
What do the free tiers actually give you?
They are shaped very differently and the shape matters more than the word count. Wispr Flow gives 2,000 words a week on desktop, every week, indefinitely, which is a real ongoing allowance you can keep using without paying. Aqua Voice gives 1,000 words for the lifetime of the account, not per month, so it is an evaluation sample rather than a free tier in any useful sense: dictate two long emails and it is spent. BlabbyAI gives 60 credits weekly with no card required, which is a recurring allowance closer in shape to Wispr Flow. If your plan is to use a tool for free rather than to trial it, a weekly reset is worth considerably more than a one-time grant.
Is Realtime Mode included in the $8 Aqua Voice plan?
No, and this is the single most misread thing about Aqua Voice pricing. Realtime Mode is the feature that shows words streaming in as you speak, and it is the thing people watch in the demo videos and assume is the product. It sits on the Max plan at $24 a month billed annually, which is $288 a year, or $30 month to month. The Pro plan at $8 annually gets you unlimited words, Custom Instructions and the expanded Custom Dictionary, but not Realtime Mode. So if streaming text is the reason Aqua Voice appeals to you over Wispr Flow, the price you are comparing against Wispr Flow is $24 a month, not $8, and Aqua stops being the cheaper option entirely.
Can either one run offline?
Neither can. Both Aqua Voice and Wispr Flow process speech in the cloud, so both need a working connection to do anything, and audio leaves your machine in both cases. This is worth stating plainly because it comes up constantly in comparisons of these two and the answer is the same for both, so it cannot be used to separate them. If offline or on-device processing is a hard requirement for you, neither of these is the tool and you want Superwhisper instead, which runs Whisper models locally. BlabbyAI is also cloud-based, so the same caveat applies to it.
Do these tools work in every application?
Yes, and this is one of the few things the whole category agrees on. Aqua Voice, Wispr Flow and BlabbyAI are all system-wide keyboard-level tools rather than per-app plugins. You press a shortcut, speak, and the text lands in whatever field has your cursor, so Word, Outlook, Slack, Teams, Notion, a browser form and a code editor are all identical from the tool point of view. Any comparison claiming one of them reaches more applications than another is usually describing a separate feature, such as meeting notetaking, rather than dictation coverage.
Which should I pick for coding?
Aqua Voice, between these two. The Avalon model is tuned for technical terms and the custom dictionary lets you teach it the library names, variable conventions and proper nouns it keeps mangling, which is precisely the failure mode that makes general dictation tools frustrating in an editor. Wispr Flow will handle prose around your code well but has no equivalent lever for vocabulary you can define yourself. Worth knowing that the same problem has a cheaper answer: custom modes in BlabbyAI are free-form instructions you write in plain English, so you can tell it how to treat code identifiers directly, at $8.49 a month rather than $96 up front.
What is the best way to decide between them?
Stop reading comparisons, including this one, and run the same twenty-minute test on each. Dictate fifty of your own real sentences, the ones you would genuinely send or commit, then count the corrections you make afterwards. That number is the only accuracy figure that reflects your microphone, your voice and your vocabulary, and it routinely disagrees with published benchmarks. Both tools have a free tier that covers a test this size, though Aqua Voice at 1,000 words for the life of the account will be nearly spent by the end of it. Add a third name while you are testing, because the marginal cost of one more twenty-minute run is small and the price spread across the category is not.
Where this lands
Between these two, the deciding factor is not quality and it is not really price either. Aqua Voice is the pick if your speech is full of terms a general model will mangle and you want a dictionary you control, and if you are willing to pay $96 up front to get the advertised rate. Wispr Flow is the pick if your speech is conversational and you want the cleanup pass doing the editorial work, and if a recurring weekly free allowance suits how you want to trial software.
The thing worth carrying away is the part the AI Overview and most of the ranking comparisons get wrong: $8 against $15 is not the real comparison. Month to month it is $10 against $15, and if streaming text is what drew you to Aqua, it is $24 against $15 and the cheaper tool is the other one. Check which plan carries the feature you actually want before you let a headline price decide.
And both leave the same gap. Neither runs offline, and neither was built for Windows first. BlabbyAI sits between them on price at $8.49 a month with no annual lock-in, was designed for Windows from the start, and gives you modes you write yourself rather than settings you toggle. The free tier needs no card, so adding it to the fifty-sentence test above costs twenty minutes and nothing else.
