Autofill web forms from a photo or file using LLM and OCR
Take a picture of a paper form with your phone and let the extension read it, removing manual transcription.
Instead of a photo, upload a document from your computer or pull one directly from Google Drive.
Text is extracted with OCR, then a large language model interprets it and maps each value to the matching web form field.
Once data is mapped, formNinja completes the fields automatically so data entry is a single action.
