Advanced: high-precision transcription (optional)

When on, SayCaps sends your image or scanned PDF to Anthropic's Claude API for a character-accurate transcription. Uncertain words are flagged as [unclear] for review. The default Tesseract path stays free and fully local — this is an opt-in upgrade.

Your key is stored only in this browser (localStorage) and goes directly from your browser to Anthropic — SayCaps has no backend. When high-precision is enabled, image data does leave your machine. Get a key →
