Turn any document into AI-ready context with agentic parsing and extraction
Content is routed to specialized expert agents for text, tables, charts and images, with recursive auto-correction loops that raise pass-through rates on messy scans and multi-modal documents.
Define the output schema you need and extraction agents return structured JSON per document, page or table row — with citations and confidence scores — without any model training.
Categorize documents with natural-language rules, segment them into logical sections, and use enterprise-grade chunking and embedding pipelines optimized for retrieval precision.
Choose Cost Effective, Agentic or Agentic Plus parsing per page, or let Auto Mode route pages to the cheapest tier that satisfies your quality bar, saving up to 80%.

Self-hosted AI workspace for local and cloud models
Connect local runtimes like Ollama alongside OpenAI-compatible and Anthropic APIs, and switch between them inside one interface.
RAG over your own documents, web search and citation-aware answers come standard, so responses are grounded in real sources.
Extend the platform with Python code to add custom tooling, preprocessing, and multi-step pipelines, then share them with others.
SSO, RBAC, audit logs, data residency, and on-premises, hybrid or air-gapped deployment for organisations with strict requirements.
