About

JustFill fills PDF forms that ordinary editors can't: fillable PDFs, flat PDFs without form fields, and scanned paper forms. Upload a PDF and AI detects the fields, including checkboxes and character-box (comb) fields. Then type the values, paste text and let AI place it, or batch-fill one PDF per row of an Excel or CSV file (PDF mail merge). Check the column-to-field mapping, preview every record, approve the ones you need and download the completed PDFs in a ZIP, or export an interactive fillable PDF (AcroForm). A reviewed layout can be saved as a template, so recurring forms are refilled without detecting fields again. The same engine is available through a REST API, a verified n8n node and an MCP server for AI assistants. The free plan includes unlimited filling and preview plus one clean download; a $7 seven-day pass gives 25 clean PDFs, and monthly plans start at $19. JustFill prepares documents for a person to review; it does not sign or submit forms.
