Unstract vs Docsumo
Document extraction can be something a team builds with prompts or something a vendor sets up for it. Unstract takes the first route: an open-source platform from Zipstack where engineers write prompts that pull fields out of PDFs and scans. Docsumo takes the second: a managed platform with pre-trained models for lenders, insurers, and finance teams, priced by quote.

Which one fits
Unstract gives engineers open-source code and prompts to build extraction themselves, while Docsumo sets up a managed platform with pre-trained models.
Choose Unstract if
- Engineers will write the extraction prompts. Document Studio turns them into an API, ETL job, or MCP server, with human review.
- You want open-source code or self-hosting. Document Studio is AGPL-3.0, and Enterprise runs in the cloud or self-hosted.
- You want posted prices. Starter is $499 a month for 5,000 pages, and overage runs $0.09 to $0.10 a page.
Choose Docsumo if
- You process bank statements, pay stubs, ACORD forms, or tax forms and want pre-trained models rather than writing prompts.
- A decision depends on a whole file. Enterprise adds case management and cross-document validation.
- You need audited security on every plan. SOC 2 Type 2, ISO 27001, HIPAA, and GDPR apply from the trial onward.
