The average desk worker types for about 2 hours a day. At voice speed, that's 48 minutes of output. The other 72? Paid to your keyboard. Every day. Without invoice. Without consent.

Voice recognition has existed for decades. Every tool that used it decided to route your audio through a server and charge you for the round-trip. Tellaflow just runs it locally.

Your voice · Tellaflow Runner-up. Zero practice.
Runs offline. Speaks multilingual. Uses Whisper & Parakeet Opensource. Sends zero data. Runs 3× speed. Lives in every app.
Works on a plane. In a bunker. Underwater (Mac permitting).
No WiFi? Great. Tellaflow doesn't need it. Local processing means full functionality everywhere humans go, including places with terrible or nonexistent internet.
Speak any of 65 languages. Type English. Fully offline.
Think in one language, output in another without a translation API, without the internet, without telling anyone what you said.
Two of the best local speech models. Both free.
Whisper by OpenAI and Parakeet by NVIDIA run on-device. No API keys. No monthly bill. Just your Mac doing what it was built for.
Your voice never hits a server. Architecturally, it can't.
Not "we promise to protect your data." Literally impossible for your audio to leave your machine. There's no server to send it to.
No server round-trip = nothing to wait for.
Cloud voice tools have latency. Tellaflow doesn't, because there's no cloud. The words appear as you say them.
Works in every app you already use.
VS Code, Notion, Slack, iMessage, Gmail, Figma, the terminal you keep open but rarely use if you can type in it, you can now speak in it.
Works with all your apps.
Tellaflow outputs to your clipboard and active cursor so it works in Slack, Chrome, Word, Notion, Figma, or any other app you already have open.
And every other app with a text cursor. Which is all of them.
You speak. We translate.
Nobody's server
gets involved.
Speak in any of 65 supported languages and Whisper transcribes and translates to English instantly all on your Mac, zero bytes sent anywhere. Most tools make you pay a translation API for this. Tellaflow just does it.
こんにちは、先週お話しした案件についてフォローアップしたいと思います。進捗状況はいかがでしょうか？次のステップについてもご確認いただければ幸いです。
Hello, I wanted to follow up on the project we discussed last week. How is the progress coming along? I would appreciate it if you could confirm the next steps as well.
Typing was never the point. It was just the only option. Humans have communicated by voice since long before keyboards existed. Then computers arrived and quietly decided fingers were the future.
Voice recognition has existed for decades. Cloud voice recognition has existed for years. But shipping your voice to a server to get text back has always felt like a deal with someone you don't quite trust. Convenient, sure. But there's a reason you lower your voice when discussing something important.
Tellaflow does one thing differently: it runs the whole model on your Mac. No server. No subscription. No latency. No one listening. Just your voice becoming your words, exactly the way it was supposed to work.
Your thoughts. Your Mac.
Your speed.
