About
Instafill is an intelligent document automation platform that transforms the tedious process of filling out PDF and Word forms into a fast, AI-driven workflow. Users upload any PDF or .docx form, and Instafill automatically detects and extracts all fillable fields using advanced PDF field extraction and LLM-based semantic mapping. Data can be sourced from uploaded documents, emails, or saved profiles, and each form is completed in as little as 25–60 seconds. The platform includes a visual PDF editor for reviewing and correcting AI-filled fields before export, field-level explanations that show the source and reasoning behind every filled value, and the ability to learn from corrections to improve future accuracy. Instafill also supports filling from previous form versions, table and list field processing, and flat-to-fillable PDF conversion for non-interactive documents. Designed for enterprise use, Instafill offers AES field-level encryption, multi-tenant workspace isolation, two-factor authentication, and multi-provider login. It integrates with over 8,000 apps via Zapier, 1,000+ via n8n, and exposes a RESTful API for custom automations. Industries served include healthcare, insurance, legal, government, construction, real estate, and financial services. With 44,783+ forms filled and a 98.2% accuracy rate, Instafill is built for teams and businesses looking to eliminate manual data entry at scale.
