Instafill

Instafill is a web-based AI form filler (with REST API) for individuals and teams that need to complete PDF and Word documents quickly and accurately.

• Multi-source autofill: extracts data from images, text documents, emails, partially filled PDFs, CSVs/Excel, and reusable profiles, then maps values to the right fields.
• Handles complex forms: supports packets up to 100 pages with hundreds of fields, including checkboxes, radio buttons, and tables/lists; converts flat/scanned documents into fillable PDFs.
• Batch and workflow automation: runs batch processing for repeated filings, supports API/webhooks, and integrates with tools like Zapier (also noted support for n8n/Make.com).
• Review and control: provides a visual PDF editor, field fill explanations, custom instructions for specialized PDFs, and learns from corrections to improve future fills.

Pricing: Paid subscription; Professional plan starts at $99/month (50 documents) and Business plan starts at $299/month (100 documents).

Notable for its security posture and compliance options, including 2FA, optional stateless mode (automatic deletion after processing), and stated alignment with ISO 27001, HIPAA, and GDPR, with hosting on Microsoft Azure in the United States.
