Speak. Siro Flow writes it.
Hold a key, say what you mean, and clean, punctuated text appears in any app. Made for people who write in Persian, English, or both in the same sentence.
Free with your own API keys · Windows 10 and 11
How it works
STEP 1
Hold the key
Hold Ctrl+Shift in any app: email, chat, a document, your code editor.
STEP 2
Speak naturally
Say it the way you would say it to a person. Pauses, restarts and changes of mind are fine.
STEP 3
Let go: it's written
Siro Flow cleans the text up and pastes it where your cursor is, usually in about a second.
Why people use it
Persian, English, or both
Built for people who switch languages mid-sentence. Persian stays in Persian script, English words stay English, and nothing is translated behind your back.
Writes like you meant it
Removes ums and false starts, applies your self-corrections ("Friday, no, Saturday"), adds punctuation and paragraph breaks.
Fits the app you are in
Casual in chat, laid out like an email in your mail app, exact identifiers in your code editor.
Your words, your shortcuts
A personal dictionary for names and terms, text snippets you can trigger by voice, and an optional signature for emails.

Common questions
Which computers does it run on?
Windows 10 and 11. A Mac version is not planned yet.
Is it really free?
Yes, with your own API keys it is free with no limit. You pay the speech and AI providers directly for what you use, which is typically a few cents an hour. Siro Flow Cloud, with no keys to manage, is coming in private beta.
Is my voice stored?
In the current version, no Siro Flow server is involved: your audio and text go from your computer straight to the speech and AI services you set up with your own keys. See the privacy policy for details.
Which languages are supported?
Persian and English, including both in the same sentence. More can be added based on demand.
Does it work in every app?
It pastes into whatever app has your cursor, as if you had typed it. A few elevated (administrator) windows may block this.
