ChatDOC
Choose it over generic PDF chatbots for one reason: it shows you where the answer came from, one click to the highlighted passage. If you are assembling your own RAG stack, the standalone parser API is arguably the more interesting half of the product.
Pros
- Every answer is anchored to its source passage, which is the entire point of the product
- Handles cross-page tables, formulas and scanned documents, not just clean text
- The parser ships as its own API, so ingestion quality can be tested independently
- Cheap next to per-seat document AI products
Cons
- Ownership and jurisdiction are not disclosed anywhere on the site, which matters for confidential documents
- Free tier is tight enough to work as a demo rather than a usable plan
- Billing runs in 30-day and 360-day blocks instead of a conventional monthly subscription
- No team or workspace tier is published
