Hold. Speak. Let go.
Speak naturally
Talk the way you talk. Mixing Bangla and English in one sentence is normal, and Kothalipi is built for it.
Let go
Your words appear wherever your cursor is: chat, email, docs, code editor.

Why Kothalipi
Built for Bangla
Most voice typing tools run models that struggle with Bangla. Kothalipi uses models fine-tuned on Bangla speech, and we test them on a public benchmark anyone can check.
Private by default
Speech recognition runs on your computer. Your voice never leaves it unless you turn on a cloud engine with your own key.
Fully open source
Every line of code is public under the MIT license. No account, no trial, no hidden data collection.
Every platform
macOS, Windows and Linux first, then Android and iOS keyboards.

Help build it
Kothalipi is made by its community. You can help even if you don't write code.
Questions
Is it free?
Yes. Kothalipi is open source under the MIT license. Offline mode costs nothing to run. If you choose a cloud engine, you use your own API key with that provider.
When can I download it?
We are building the first desktop version now. Watch the GitHub repo to get notified when the first release is out.
Where do my recordings go?
Nowhere. In offline mode audio is processed on your device and discarded. Cloud mode is optional and always off by default.
Can it handle Bangla mixed with English?
That is a core goal. Mixed speech is part of our test set from day one, and we publish how each model does.
Will it support other languages?
Yes. Bangla comes first, and the project is designed so any community can add its language, including romanized forms like Hinglish or Arabizi.
