PDF.ai: ~242k visits/mo · growing (the only major pure-play still up) · GPT (OpenAI) with Pinecone retrieval
PDF.ai is the only major standalone "chat with PDF" tool still growing, and it leads with an API and developer story. It is English-only and has the weakest accuracy reputation of the leaders, with billing complaints reported. pdf.chat counters with grounded, page-cited answers, free OCR, and aggressively gated localization that PDF.ai does not offer at all.

वारंवार विचारले जाणारे प्रश्न
If you want grounded, verifiable answers, yes. pdf.chat is built around Claude-native, page-cited answers, free OCR for scanned files, and a genuine free tier: the areas where users most often look past PDF.ai.
PDF.ai runs on GPT (OpenAI) with Pinecone retrieval. pdf.chat is Claude-native and, on Pro, returns exact-span citations through the Anthropic Citations API, so every sentence links to the precise source passage, not just a page number.
PDF.ai is English-only. Localization is one of pdf.chat's core advantages: pages ship in a language only once they are at least 90% translated.
Both cite sources, but PDF.ai stops at page-level. pdf.chat matches that on its free tier and goes further on Pro with exact-span citations you can click to highlight the source text, the verification bar for legal, research, and financial work.
pdf.chat has a real free tier with no signup and no $1-to-$19.99 trial trap, and cancellation is one click online. Compare current prices on PDF.ai's own site (they change often), but the free tier means you can try pdf.chat at no cost first.
Yes. There is nothing to migrate. Upload the same PDFs to pdf.chat and start asking. Your PDF.ai account is unaffected, so you can run both side by side and compare the answers before you decide.
