What our research says

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

DocXter

A document chat tool with two things most rivals skip: several documents in one conversation, and OCR so scans are not dead weight. The persistent knowledge base means you stop re-uploading the same files. Credits and per-plan user counts are the real constraint, and the free tier's three-day history makes it evaluation-only.

Pros

Queries several documents in a single conversation rather than one file at a time
OCR brings scanned and photographed documents into scope
A persistent knowledge base and unlimited history on paid tiers
Answers in fifteen or more languages, including Hindi and mixed Hindi-English

Cons

File support stops at DOCX, PDF, TXT and PPTX; spreadsheets and images are not covered
The free tier keeps document history for only three days
Advertised monthly prices are annual-billing rates, so monthly billing costs more
No API, and seat counts are capped per tier
