Introduction

Both Reducto and Rossum transform unstructured documents into structured data, but they are optimized for different buyers and workflows. Reducto is an API‑first ingestion and extraction engine built for LLM‑ready outputs, complex layouts, and enterprise deployment options. Rossum is an end‑to‑end, cloud‑native IDP platform focused on transactional documents (e.g., invoices, POs) with built‑in validation, approvals, and email automation.

Key takeaways

Reducto is best when you need developer‑grade parsing accuracy on messy, multi‑format content (PDFs, spreadsheets, slides), citation‑ready chunks, custom schemas, and strict deployment models (including on‑prem/air‑gapped).

Rossum is best when you want a full workflow layer around transactional paperwork with validation, business rules, approvals, and “copilot” style automations—delivered as a managed cloud platform. Sources: Platform overview, Trigger actions, Email automation press release.

Where Reducto fits best

You need LLM‑ready, citation‑rich outputs from complex, messy documents (multi‑column reports, scanned contracts, dense tables, spreadsheets) with high fidelity. Sources: Document API, RD‑TableBench.
You require deployment flexibility (VPC, regional, on‑prem, or air‑gapped) and strict privacy controls (zero data retention, HIPAA). Sources: Security policies, Enterprise sales.
Your team is building LLM applications and wants structured JSON, custom schemas, and chunking optimized for retrieval and grounding. Sources: Docs overview, Elasticsearch guide.

Where Rossum fits best

You want a managed, workflow‑complete platform for transactional documents with approvals, exception handling, business rules, and automated communications. Sources: Platform, Trigger actions.
Your scope centers on AP/AR, P2P, logistics, and finance back‑office processes where straight‑through processing and validation against master data are critical. Source: Validate & augment data.
You prefer cloud deployment with regional hosting and optional single‑tenant isolation, plus broad language coverage (276 languages). Sources: Security & trust, Platform.

Evidence and claims: how to interpret them

Reducto publishes open benchmarks (e.g., RD‑TableBench) and case studies with quantified outcomes in healthcare and finance. Sources: Anterior, Benchmark.
Rossum’s Aurora announcements cite human‑level accuracy, zero hallucinations, and rapid “instant learning” on proprietary datasets; treat these as vendor‑reported results unless validated in your environment. Sources: Aurora press release, Aurora 1.5.
