Surya alternatives

Surya ranks #3 of 7 for extract data from documents with an evidence score of 42/100. Its weak spot: The licence is not plain open source above a revenue line - read it before shipping. 6 other tools are ranked for the same job (extract data from documents); 2 score higher, 4 can be used free and 2 are open source. Same public signals as the ranking, recomputed nightly — nothing here is sponsored. Read the Surya review.

1
Unstructured Open source
Ingest library and hosted pipeline that normalises 25+ file types into chunks for retrieval.

+ The connector list is the real product - S3, SharePoint, Confluence and Drive land as clean chunks.
− The open library's best parsing paths push you toward the paid API.

Docling Open source
Turns PDFs, Office files and scans into structured markdown or JSON, layout and tables intact.

+ Reads a table as a table, and does it on your own machine with nothing sent anywhere.
− Heavy scanned documents want a GPU; CPU-only runs are slow on long PDFs.

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

+ Holds up on financial statements and forms where plain text extraction turns to soup.
− Per-page pricing and a cloud round trip; large archives add up fast.

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.
− Narrow by design - a plain business PDF is better served elsewhere.

5
Extracts fields from invoices, receipts and forms, then posts them into an accounting system.

+ Ships the boring half: approval steps, validation rules and exports to QuickBooks or SAP.
− Priced for finance teams, not for a side project.

Reducto Paid
Developer API that splits dense documents into structured blocks with coordinates and citations.

+ Every block comes back with a page position, so an answer can cite exactly where it came from.
− API only and priced per page - no interface for someone doing this once.
