Download started
Thanks — UtterAI is on its way.
Your download should have begun automatically.
Preparing your download…
Wrong platform? Windows installer · Debian / Ubuntu · Linux AppImage · Windows MSI
First run
- Open UtterAI. A short intro explains what it does and lets you turn automatic update checks off if you'd rather they were.
- Pick a file. Choose an audio or video file, or drag one onto the window. MP3, WAV, M4A, FLAC, OGG, MP4, MKV, MOV and more.
- Choose how much. Transcribe the whole thing, or drag the handles to a range and do just those few minutes.
- Press Start. The built-in model needs no download, so the first transcription works offline straight away.
- Read, fix, export. Click a line to play it, double-click to correct a word, then export to TXT, SRT, VTT, Markdown or JSON.
Verify what you downloaded
Every release is built in the open by GitHub Actions, and the SHA-256
below comes from that build's own checksums.txt — not from
anyone typing it in. If the hash of your file matches, the file is
byte-for-byte what the workflow produced. This is optional; skip it if
it isn't your sort of thing.

Check it yourself:
If something goes wrong
Windows says "Windows protected your PC"
UtterAI isn't code-signed yet — a certificate costs a few hundred pounds a year, and this is a free project. SmartScreen shows that warning for any unsigned installer. Click More info, then Run anyway. If you'd rather not, verify the SHA-256 above first: it proves the file is exactly what the public build produced.
The AppImage won't start
It needs the executable bit: chmod +x UtterAI_*.AppImage.
On some minimal systems it also needs FUSE
(sudo apt install libfuse2). Failing that, run it
extracted: ./UtterAI_*.AppImage --appimage-extract-run.
Audio won't play in the preview on Linux
The window uses your system's GStreamer codecs for playback. The
AppImage bundles them; a .deb install uses whatever your
distribution has. If a file's preview is silent, install the codec
packages:
sudo apt install gstreamer1.0-plugins-good gstreamer1.0-plugins-bad gstreamer1.0-libav.
Transcription itself is unaffected either way — it doesn't use
GStreamer.
Transcription is slower than I expected
Speed depends on your CPU and the model. The built-in Base model runs several times faster than real time on a modern machine; Medium and Large (Turbo) are much more accurate and much slower. Transcribing a range rather than a whole recording is the quickest win.
It says the model is unavailable
The Base model ships inside the installer and is copied into place on first launch. If that copy failed — usually a full disk — open Settings, check the free space shown under Privacy & storage, and download a model from the list.
Something else
Open an issue with what you were doing and what happened: report a bug. Turning on Developer mode in Settings adds the technical detail to error messages, which helps a lot.
