📖 How to use

  • Enter the requested source text, context or document.
  • Choose available style, format or target options.
  • Run the tool and wait for the local model to load or generate.
  • Review the result before using or publishing it.

⚡ How it works

  • WebGPU browsers use a quantized Qwen2.5 0.5B instruction model.
  • Other supported browsers fall back to a smaller SmolLM instruction model.
  • First run downloads model files; later visits may reuse browser cache.
  • Verify important facts, code, formulas and translations.

💡 Privacy & limits

  • Paste the video transcript or captions; this free version does not bypass YouTube caption access controls.
  • The optional URL is reference context only.
  • Model downloads can be large and performance depends on your device.
  • Do not paste passwords, private keys or highly sensitive information.
