PDF.ai review

PDF.ai does one job, chatting with PDFs, and prices it simply. The free Hobby plan allows 1 PDF upload and 100 questions a month with a 10MB file limit, enough to try it on one document. Pro costs $10 a month billed yearly and raises the limits to 100 PDFs and 1,000 questions a month, 50MB files and OCR on 10 pages per file for scanned documents. Ultimate at $20 per user a month billed yearly removes upload and question caps, switches to the Advanced AI model and raises OCR to 50 pages per file. A Chrome extension is included on every plan, and developers can use separate Parse, Extract and Chat APIs. The weak spots are the tight free plan and the per-file OCR caps, which matter for long scanned contracts. Pro also uses the Basic model, so harder questions favor Ultimate or a general assistant.
