Translay

Translate and dub videos from English into Spanish in each person's own voice. Everything runs on your machine, on your GPU.

Dubbing in their own voice

Whisper transcribes, Opus-MT translates and OmniVoice clones the voice of each person in the video. The voice stays in sync with the picture.

YouTube and files

Paste a link, a playlist or a CSV with thousands of links; they are downloaded and processed automatically in a queue.

Libraries

Collections, channels, categories and search across all transcripts. Each library in its own folder.

Desktop app

A Windows installer: the app sets up Python, the server and the voice engine by itself, and opens Translay in its own window.

API and webhooks

Everything the app does is also available over HTTP, with per-library keys and signed notifications.
