AI auto captions
transcribe, time, and burn locally
Generate accurate captions automatically from local transcription. EditAssist transcribes every word on your own machine, times them precisely, and burns them into the video or exports as SRT/VTT. No cloud upload, no per-minute fees.
Workflow
Ingest your video and the agent transcribes every word locally using Whisper-based models. It detects speaker changes, handles overlapping dialogue, and supports multiple languages. The resulting captions are timed to the millisecond and can be reviewed and edited as text before export.
Burn captions directly into the video with customisable fonts, positions, and safe-area margins, or export as SRT, VTT, or embedded track for broadcast compliance. The entire pipeline runs on your GPU. No per-minute fees, no upload limits, no cloud dependency.
