vinishkapoor · reddit · 2026-11-13

Developer vinishkapoor released a browser-based video editor that runs entirely on-device: nothing is uploaded, no sign-up, no watermark, free to use.

Features

Multi-track timeline with unlimited video/overlay/audio tracks, snapping, zoom, split (S), per-track lock/hide/mute
On-device AI tools: word-level auto captions, green-screen-free background removal, silence removal, voice enhancement, auto music ducking, face/area blur — powered by small models downloaded on first use
12 caption styles, .srt import/export, 14 filters, 12 transitions, PiP/split-screen layouts, 480p–4K export
A search box that takes you to the right option

Build notes with Claude Code

Timeline feel came first, then feature-by-feature rounds of build → test with real footage → fix
Keeping everything on-device was the core constraint; making the small models run smoothly took many iterations
Export was the hardest: MP4 assembled in memory without OOM on normal machines
