Comparison
Diktat vs. Aqua Voice
Aqua Voice is a dictation service that runs in the cloud. It takes into account what you are writing, and you can keep editing the text by voice. You pay by subscription.
Diktat solves the same task from the other end: recognition on the device, no rewriting, one purchase. No account, no server. Prices, limits, and platforms sit side by side below.

The core difference.
With Aqua Voice, dictation is a dialogue. The AI takes into account what is on screen, and you can have the text restructured by voice. That needs a service, an account, and a subscription.
With Diktat, dictation is a tool: speak, stop, text in the clipboard. Recognition runs on the device. What you say never goes online, and no word changes unless you ask. There is no account. There would be nothing to manage.
On price, it is $8 to $24 a month versus one purchase. Diktat costs from €9.99 at launch, later €19.99. iPhone, iPad, and Apple Watch are all in that one purchase. The Mac app is separate. Aqua Voice's cheapest plan costs more in a year than Diktat costs once.
When Aqua Voice is the better fit.
You want more than dictation. You want to edit the text by voice, shaped by the context of the app you are in.
You work in a team. Aqua Voice has a plan built for that.
You want to try before you pay: Aqua Voice gives you 1,000 words a month for free. And a subscription does not bother you.
When Diktat is the better fit.
What you say should not leave your device. With Diktat there is no service in between.
You want predictable text. No language model reshapes what you said.
You want to pay once and keep the app, on iPhone, iPad, and Apple Watch.
Questions about the comparison.
Is Aqua Voice free?
Aqua Voice has a free tier of 1,000 words a month (as of 5 August 2026). After that it costs from $8 a month. Diktat counts dictations instead of words: 5 a day stay free, however long they are.
Does Aqua Voice need internet?
Yes, Aqua Voice is a cloud service, so recognition runs there (as of 5 August 2026). Diktat recognizes on the device. Once the model is downloaded, a dictation needs no connection. Only the Apple recognition fetches language packs when needed.
Can Diktat edit text by voice like Aqua Voice?
No, Diktat transcribes and puts the text in the clipboard. No language model edits, formats, or summarizes it, not even as an option. If you want to edit while you dictate, Aqua Voice fits better. If you want your words unchanged, Diktat fits.
What does Diktat cost?
Diktat costs from €9.99 at launch as a one-time purchase, later €19.99. One purchase covers iPhone, iPad, and Apple Watch. You pay for the Mac app separately. 5 dictations a day are free without buying anything.
