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.
