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.
PDF generation API and MCP server for AI workflows
Create a reusable template once, then generate unlimited documents by sending fresh JSON payloads — ideal for invoices, certificates, reports, and receipts.
Describe the document you need and provide example data, and Peedief drafts a reusable template with dynamic fields, repeated rows, and print-ready layout.
Every response returns a hosted PDF link plus a preview URL you can embed in an iframe for portals, approval screens, and customer review flows.
Use your own HTML/CSS templates with loops, conditionals, page breaks, headers, and footers while Peedief manages rendering, fonts, and delivery.
