Susurro vs Wispr Flow
Both do the same thing: you speak and the text appears right where your cursor is. The real difference is a single one, and it matters: where your voice gets processed. Wispr Flow sends it to its servers; Susurro transcribes it on your computer, and it never leaves.

Pick Susurro if…

- You want to pay 3× less: €4.99/month versus $15/month.
- You sometimes work offline (flights, trains, locked-down company networks).
- You use Windows and want live translation into English as you speak.
Pick Wispr Flow if…
- You also need to dictate on Mac, iPhone or Android.
- You want an AI to rewrite your sentences and adjust the tone for you.
- A limited free plan (2,000 words per week) is enough, and you don't mind your voice going through their servers.

The core difference: where transcription happens
Every time you dictate with Wispr Flow, your audio is compressed and travels over the internet to their servers. It gets transcribed there and the text comes back to your screen. It works well, but it means two things: no connection, no dictation, and everything you say — client names, figures, personal matters — leaves your computer.
Susurro does that same job inside your PC. The speech model is downloaded once, and from then on transcription is local: you can dictate a password, a contract or a medical report knowing that nobody else hears it. Not even us.
For home use it may feel like a nuance. If you dictate work matters, it's the difference between complying with your company's data policy and breaking it without noticing.
What it costs you per year
Wispr Flow Pro costs $15 per month, or $12 per month if you pay the year upfront. Susurro has a single plan at €4.99 per month with everything included, and the first month is free with no card.
Where Wispr Flow wins, we say so
Wispr Flow runs on Mac, iPhone and Android as well as Windows; if you dictate from your phone, Susurro can't help you today. Its AI can rewrite your sentence to adjust the tone (more formal, shorter), something Susurro doesn't do: Susurro types what you say, cleaned of filler words, but doesn't reinterpret it. And its permanent free plan, though capped at 2,000 words a week, does exist.
If those things outweigh privacy and price for you, Wispr Flow is a fine app. If you dictate from Windows and would rather keep your voice on your own computer while paying a third of the price, that's what Susurro is for.
Frequently asked questions
Does Wispr Flow work offline?
No. It transcribes on its servers, so it needs a constant connection: without internet you can't dictate. Susurro processes your voice on your computer and works the same with or without a connection.
Do they transcribe equally well?
Both use state-of-the-art speech recognition and both understand 100+ languages with automatic detection. On top of that, if your PC has an NVIDIA card, Susurro uses it and transcribes much faster.
Can I try Susurro for free before deciding?
Yes. The first month is complete and free, no card required. If it's not for you, there's nothing to cancel.
Is it easy to switch from Wispr Flow?
Yes. Susurro is also driven by a keyboard shortcut and types wherever your cursor is, so the gesture is the same. Install it, set the shortcut you already have in your muscle memory, and keep dictating.
