Overcaption Overcaption

Overcaption is a free desktop subtitle studio for macOS (Apple Silicon) and Windows 10/11. It transcribes video on your machine with Whisper-class speech recognition (word-level timestamps, hallucination filtering), gives you a modern editor to fix text and timing (waveform timeline, keyboard shortcuts, reading-speed and line-length checks), translates locally to around 50 languages with downloadable models, and exports SRT, VTT, ASS and TXT or burns styled subtitles directly into the video without watermark. Everything runs offline — no account, no uploads, nothing leaves your machine. The core app is free with no time limit; a few advanced Pro features are paid.
