AI that fills your PDF and Word forms for you
Automatically detects and maps every field in a flat PDF or Word form, using semantic understanding rather than rigid templates.
Each filled field can display its source and the reasoning behind the value, making verification fast and auditable.
Runs concurrent parallel field filling and handles structured row data, so multi-form packets and repeating tables are completed together.
An MCP server lets you fill PDFs from inside Claude Desktop, Code, or ChatGPT, plus n8n and Zapier automations for wider workflows.
An AI-powered visual workspace where teams think, plan, and build together
An infinite multiplayer board where cursors, comments, and live editing let remote and hybrid teams work in the same space simultaneously.
Docs, Tables, Slides, Kanban, and Timelines live alongside freeform drawing so a workshop can turn directly into a structured plan.
Generate diagrams, tables, and summaries, remove image backgrounds, and connect external AI assistants through the MCP server.
6,000-7,000+ templates for brainstorming, workshops, roadmapping, and process mapping give teams a running start.
