Free offline speech-to-text & subtitles (SRT/VTT) in 99 languages on any GPU — AMD, NVIDIA, Intel, Apple. Whisper via whisper.cpp + MCP server for Claude, Codex, Gemini CLI.
babelscribe — free, offline speech-to-text and subtitles on any GPU (AMD, NVIDIA, Intel, Apple)
babelscribe turns any audio or video file into subtitles (SRT, VTT) and text, in any of Whisper's 99 languages, on your own graphics card — AMD Radeon, NVIDIA, Intel Arc or Apple Silicon — or the CPU. No CUDA needed, no cloud, free (MIT). It runs OpenAI Whisper through whisper.cpp with Vulkan, CUDA or Metal, and works from the command line, from Python, or from AI apps (Claude, Codex, Antigravity, Gemini CLI, Cursor) as an MCP server.
babelscribe is a thin, friendly layer on top of whisper.cpp. It exists because getting fast Whisper on a non-NVIDIA card (e.g. an AMD Radeon on Windows) still means building whisper.cpp with the Vulkan SDK yourself. babelscribe downloads a prebuilt whisper-cli for your system and handles the rest.

A 19-minute English TED talk transcribes in 48 seconds on an AMD Radeon RX 9070 XT with 1.5% word error — see the benchmark below.
Use it from an AI app (MCP) — no terminal needed babelscribe is also an MCP server, so any AI app that supports local MCP servers can transcribe files on your computer with your GPU. Ask in plain words — "make Thai subtitles for the newest video in my Downloa
