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.
Automate data entry across websites, apps and PDFs from your browser
Select a formatted table on a website, web app or local PDF and copy it to the clipboard with its rows and columns preserved, ready to paste into a spreadsheet.
Import a spreadsheet, map its headers to a form's input fields and fill text boxes, radio buttons and checkboxes from the matching row in a few clicks.
Smart Paste identifies familiar fields like name or occupation so you can pull just those values out of a page instead of copying everything.
Every extraction and paste happens on your own computer, so the data you work with is never uploaded to a third-party server.
