Describe a form in plain English and AI builds it — submissions become finished documents
Describe the form you need and the AI produces the fields, labels and structure, removing manual drag-and-drop work.
Each response is automatically formatted into a completed document or PDF, ready to file, send or archive.
Apply your logo, brand colors and custom domain so shared forms look like part of your own product.
Send submissions to email or webhooks so responses land in your inbox or CRM without manual exports.

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.
