Overview

PDF.ai does one job and keeps its scope honest: you upload a document, and then you interrogate it in chat. Answers come back with citations to the source pages, so you can jump straight to the passage and confirm it rather than taking the model's word — which matters enormously when the document in question is a contract or a research paper. It handles multiple documents in one conversation, offers a Chrome extension so you can query a PDF you are already looking at in the browser, and exposes an API if you want the same capability inside your own product. The limits are the usual ones for a small, focused SaaS. The free tier is a taster — a handful of documents and questions — and everything meaningful requires a subscription. Documents go to their cloud, which is a real consideration for legal or medical files. And because it is a thin layer over a language model, quality on complex tables, scanned pages and equations is patchy. Fine for prose, less so for structured data.
