About Speech to Text
Turn interviews, lectures, voice memos and meetings into text. Kitbly runs OpenAI's open-source Whisper model directly in your browser (WebGPU where available), so recordings are never uploaded. Choose fast, balanced or accurate mode, edit the result with timestamps and download TXT, SRT or VTT. Works with MP3, M4A, WAV, MP4, MOV, WEBM and more.
Frequently asked questions
Is it free?
Yes. Free with no sign-up, no watermark and no hidden limits on pages or files beyond what your device can handle.
Are my files uploaded?
No. This tool runs entirely in your browser – your file never leaves your device and works even with a weak connection once the page has loaded.
How long can the recording be?

Is there a faster option?

Which languages?
Whisper understands 90+ languages and can also translate speech into English.
