Your file never leaves your device. Processed locally with WebAssembly. Nothing is uploaded.

Great for voice memos, interviews and lectures

Journalists, students and researchers use audio transcription to search and quote recordings. GustKit gives you a clean text with optional timestamps, so you can jump back to the exact moment in the recording.

Export the way you work

Copy the text, save a TXT, download a DOCX to edit in Word or Google Docs, or export SRT/VTT if the audio belongs to a video you are subtitling.

Privacy by design

Interviews and medical or legal notes are sensitive. Because the speech model runs locally, the recording never touches our servers. There is nothing to leak, retain or delete.
