The top alternatives to Reducto in the RAG Frameworks space, compared on features, pricing, and what they're best at.
Reducto is a Series B-funded AI document intelligence platform built by MIT engineers featuring state-of-the-art vision models that read documents like humans do, solving critical bottlenecks for AI teams working with unstructured data. The platform extracts structured data directly from documents with schema-level precision, handling invoice fields, onboarding forms, financial disclosures, and more across PDFs, images, spreadsheets, slides, and other formats through a single unified API. Since their Series A announcement, Reducto's monthly processing volume has grown by more than 6x, now processing close to a billion pages of data for leading technical teams including Harvey, Mercor, and Rogo, as well as enterprise clients including a Fortune 10 company, a Global Top 5 Hedge Fund, and category leaders across Healthcare, Insurance, and Real Estate. In July 2025, Reducto expanded beyond document reading with Reducto Edit for document generation capabilities.
