transcriptasm

Offline speech-to-text in the browser via Whisper WASM. Nothing is uploaded.

Live: https://transcriptasm.quad4.io

Whisper weights, ONNX hybrids, and transformers.js are not in git. The Docker image downloads them at build time and ships a full offline stack. For a local source build, run make assets once (custom whisper WASM is already under web/vendor/whisper/).

Install (Docker)

Clone and build (downloads all models/WASM into the image):

git clone https://github.com/Quad4-Software/transcriptasm.git
cd transcriptasm
docker compose up --build

Open http://127.0.0.1:8080.

Pre-built multi-arch image (linux/amd64, linux/arm64):

docker pull ghcr.io/quad4-software/transcriptasm:latest
docker run --rm -p 8080:8080 ghcr.io/quad4-software/transcriptasm:latest

Or with Compose against the published image:

git clone https://github.com/Quad4-Software/transcriptasm.git
cd transcriptasm
IMAGE=ghcr.io/quad4-software/transcriptasm:latest docker compose up

Coolify: use docker-compose.coolify.yml and set the domain to container port 8080.

Bind on all interfaces: HOST_PORT=0.0.0.0:8080 docker compose up --build.

Release binaries

Tagged releases publish static Go servers for Linux, Windows, macOS, FreeBSD, OpenBSD, NetBSD (amd64, arm64, arm, 386, riscv64, and other supported arches).

# example
curl -LO https://github.com/Quad4-Software/transcriptasm/releases/latest/download/transcriptasm_X.Y.Z_linux_amd64.tar.gz
tar xzf transcriptasm_*.tar.gz
./transcriptasm -web /path/to/web -addr :8080

The binary serves a web/ tree. For a full offline tree, clone the repo and run make assets, or use the container image (recommended).

Build from source

Needs Go 1.26+ and Node (for tests).

git clone https://github.com/Quad4-Software/transcriptasm.git
cd transcriptasm
make assets
make build
make run

make test
make check

Binary: bin/transcriptasm (default listen :8080, web root web).

Regenerate whisper WASM (needs emsdk): make whisper-wasm.
