FFmpeg WASM + WebCodecs in browser, but only useful if you use WigglyPaint.
In-browser video converter with offline support, but remove.bg-style privacy angle is already standard for ffmpeg.wasm tools.
Nostalgic film camera GIF converter—clever niche tool, but one-trick utility for a single obscure camera.
Everything actually runs locally — the site even dares you to open the Network tab or disable Wi‑Fi while converting video→GIF. It's not a new category (ezgif, ffmpeg.wasm clones exist), but packing 26 discrete, offline tools into a single, no-account interface is legitimately useful for people who care about privacy. Would be more notable with batch processing, scripting hooks, or clear provenance for the WASM modules, but as a browser utility it nails the core promise.
LLM-generated HTML animations recorded as video—fun but fragile and not repeatable.
EZgif exists, but this focuses purely on chaotic layering without watermarks.
