Instafill.ai

Instafill.ai is a browser-based AI form filler for PDF and Word documents. Users upload a form, and the AI identifies every field, checkbox, table and radio button, then fills them using information from uploaded documents, typed answers, or data from earlier fills. The page states that completed forms can be reviewed and edited in a visual PDF editor before export, that fills take roughly 25 to 60 seconds, and that documents up to 100 pages are supported. It also converts flat PDFs, scans and images into fillable PDFs, supports batch filling from CSV files, and offers an API, webhooks, and integrations with Claude and ChatGPT via MCP, n8n and Zapier. The page highlights security features including stateless mode that deletes files after processing, optional two-factor authentication, AES encryption of field-level answers, and data hosting on Microsoft Azure with selectable regions. It states that user data is not used to train AI models and that a BAA is available for handling protected health information.
