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%.

Collaborative inbox and email management for teams
Let multiple people work the same inbox with clear assignment, internal statuses, and visibility into who is answering what.
Discuss and prepare replies inside the email thread itself, so context stays attached and nobody is left out of the loop.
Turn any email into an assigned task and see what each teammate is working on today, tomorrow, and next week.
Automate repetitive routing, tagging, and follow-up with rules, rule templates, and workflow automations.
