Tell her Thursday works but not before 3, deck tonight.

For Mac and Windows
Reply to anything.
Just say it.
Hold Right Option in any reply box and say the gist. TalkOS reads the conversation and writes the whole reply in your voice. You press Send.

Same email, same four seconds of talking. Three very different results.
MR Marta Ruiz to you
Could we move our review to Thursday? 3pm would be ideal. Can you send the deck before then?
You say: “tell her thursday works but not before 3, deck tonight”
ChatGPT

Gets there, slowly. Five steps and two apps for every message. Most people give up and type it themselves.
TalkOS
Hi Marta,
Thursday works for me, just not before 3pm. I’ll send the deck over tonight so you have it before the review.
Best,
Pier
Writes the reply. It read Marta’s email, so it knew what you were answering: greeting, the right tone, your sign-off. In the box, ready to send.
Not just email.
Slack, support tickets, LinkedIn, or a language that isn’t your first. Same key, same idea: say the gist.

How it works
Hold. Speak. Let go.
-
1 Hold Right Option
Click into any reply box, in any app, and hold the key.
-
2 Say it your way
Say the message, or just what it should say. Ramble. It cleans up.
-
3 Let go. It lands.
The reply appears in the field, written like you. You read it and press Send.
It reads, writes, edits and remembers.
It reads the thread
While you hold the key, TalkOS reads the conversation around the box, so “tell her yes” turns into a reply that fits it.
Real recording · Gmail in ChromeWrites like you
Your name, your sign-off, your length and tone. When you change a draft before sending, it learns from that.
Remembers what you promised
After a reply, one click saves a person, a promise or a note. Nothing is saved unless you click.
Fix it by voice
Hold Right Option and Command and say how to change it: “make it a bit warmer”. It’s rewritten in place, and ⌘Z puts the original back.

The right shape, every time
Email gets a greeting and a sign-off. Chat stays short. Same key.
In your language
Speak in any language your computer can transcribe. Or write in English and say “translate to German” with the edit key.
Privacy
It listens when you ask. Not before.
Your voice stays on your computer.
Speech is turned into text on your Mac or PC. The recording never leaves it.
The text goes out only to write the reply.
When you let go, what you said and the conversation on screen go to our server and to OpenAI, which writes the reply. We don’t store it, and it isn’t used to train AI models.
Reads only while you hold the key.
No background watching. It looks at the conversation when you press, and you can turn that off.
Never sends a thing.
The reply waits in the field. You read it, change it if you like, and press Send yourself.

How is it different from Wispr Flow or ChatGPT?
Dictation apps like Wispr Flow and Superwhisper are made to turn what you say into clean text. TalkOS is made for replies: it reads the message you’re answering and writes the whole reply, so you only say the gist. ChatGPT can write replies too, but you copy the thread over, write a prompt and paste the answer back. TalkOS does that with one key, in the box you’re already in.
Is my text used to train AI?
No. The conversation and what you said go to our server and to OpenAI only to write the reply. We don’t store them, and under OpenAI’s API terms they aren’t used for training. OpenAI keeps them for up to 30 days for abuse checks, then deletes them. Your voice never leaves your computer.
Where does the reply go?
Into the text box you clicked: a Gmail or Outlook reply, a Slack message, Mail, Messages, or any field in your browser. TalkOS doesn’t open a window of its own.
Does it ever send for me?
No. The reply waits in the field until you press Send.
What does adding Command do?
Right Option and Command edit the text that’s already in the field. Say “shorter”, “warmer”, “fix the date to Friday” or “translate to Italian”. ⌘Z puts the original back.
Is it listening all the time?
No. It listens only while you hold the key, and turns your speech into text on your computer.
Does it learn how I write?
Yes. Set your name and sign-off, pick length and tone, and when you change a draft before sending, it keeps your wording as an example, on this Mac.
What do I need?
A Mac on macOS 26 or later, or a Windows PC, and a microphone. On Mac, TalkOS asks for two permissions: Microphone and Accessibility.
How do I install it?
On Mac: download the disk image, drag TalkOS to Applications, and open it. It lives in your menu bar. On Windows: download and run the installer. It lives in the system tray. Both update themselves.
The box is open.
