About Instafill
Instafill is a web-based AI form filler with a REST API designed for individuals and teams that need to complete PDF and Word documents quickly and accurately. It supports multi-source autofill by extracting data from images, text documents, emails, partially filled PDFs, CSVs or Excel files, and reusable profiles, then mapping values to the correct fields. The tool handles complex forms, including packets up to 100 pages with hundreds of fields such as checkboxes, radio buttons, and tables or lists, and can convert flat or scanned documents into fillable PDFs. Instafill enables batch processing for repeated filings, supports API and webhooks, and integrates with tools like Zapier, with noted support for n8n and Make.com. It provides a visual PDF editor, field fill explanations, custom instructions for specialized PDFs, and learns from corrections to improve future fills. The platform emphasizes security and compliance, offering 2FA, an optional stateless mode that automatically deletes data after processing, and alignment with ISO 27001, HIPAA, and GDPR standards, with hosting on Microsoft Azure in the United States.
