  • 20+ looks — Hormozi box, karaoke fill, neon, glow, comic, retro 3D, serif accents and more. Every look renders identically in the preview and the export.
  • Edit everything — words, timing, line breaks, key words, position, fonts (400+ Google fonts or your own), colours, motion.
  • Hindi / Hinglish in Roman script with a fine-tuned Whisper model (Oriserve Whisper-Hindi2Hinglish-Swift, converted to ONNX with word timestamps).
  • Exports: MP4 with burned-in captions, SRT. The optional desktop helper adds transparent overlays (ProRes 4444 / WebM alpha) for Premiere, Resolve and CapCut.
  • No signup to try, no watermark.

  • Runs in your browser. Speech recognition is Whisper running on WebGPU / WASM in your tab (transformers.js). Rendering is the same Remotion composition the preview uses, encoded with WebCodecs. Your video is never uploaded.
  • 20+ looks — Hormozi box, karaoke fill, neon, glow, comic, retro 3D, serif accents and more. Every look renders identically in the preview and the export.

Run it locally

Requirements: Node 20+, pnpm, a free Supabase project.

git clone https://github.com/Ishaan-Gpt/Captions-Easy.git
cd Captions-Easy
pnpm install
cp apps/frontend/.env.example apps/frontend/.env.local   # fill in your Supabase keys
pnpm dev                                                 # http://localhost:3000

Checks:

pnpm typecheck
pnpm test
pnpm build

Database: supabase/migrations currently holds the later migrations only; a full schema snapshot is on the way. Until then, open an issue if you want to self-host and we'll help.

Licensing

CaptionsEasy's own code is MIT.

It is built on Remotion, which has its own license: free for individuals and small teams, but companies above Remotion's free tier need a Remotion company license to use it. If you fork CaptionsEasy for a business, check Remotion's terms.

Fonts and speech models keep their own licenses (Google Fonts: OFL / Apache; Whisper models: MIT / Apache-2.0).

Contributing

Issues and PRs are welcome — see CONTRIBUTING.md. Good first areas: new caption looks, language support, editor polish.

If CaptionsEasy saved you time, a ⭐ helps a lot.
