Docling alternatives

Docling ranks #3 of 9 for chat with PDFs & documents with an evidence score of 64/100. Its weak spot: Heavy scanned documents want a GPU; CPU-only runs are slow on long PDFs. 13 other tools are ranked for the same jobs (chat with PDFs & documents, extract data from documents); 2 score higher, 11 can be used free and 2 are open source. Same public signals as the ranking, recomputed nightly — nothing here is sponsored. Read the Docling review.

NotebookLM Free tier
A grounded research notebook that answers only from the sources you upload and can turn them into Audio Overview podcasts.

LlamaParse Free tier
Parsing service aimed at the documents that break parsers: nested tables, forms, figures.

Le Chat Free tier
Mistral's European chat assistant with fast Flash Answers, web search, document upload and image generation.

+ Very fast responses and EU-hosted data handling, with a cheaper Pro tier than the US incumbents.

Mathpix Free tier
Screenshots and PDFs of maths and chemistry into LaTeX, markdown or Word.

+ Still the most accurate thing there is at equations, which general OCR gets wrong.

ChatPDF Free tier
Upload a PDF and ask questions about it in chat, with answers linked to page references.

+ Zero setup: drop a PDF and start asking, with page citations for every answer.
