Good to know
Long documents are summarized in parts and then combined. Only the text is sent to the AI service, after you agree. Check important figures against the original.
FAQ
Is my file uploaded to a server?
The PDF itself is not uploaded. Once you agree, only the text extracted from it is sent to an AI service (Cloudflare Workers AI) for processing; FileCustom doesn't keep the content. Don't use it for confidential documents.
Is the AI always right?
Not always — double-check anything important. Scanned files need OCR PDF first so the AI has text to read.
