What is Instafill?

Instafill.ai is an AI‑powered PDF and Word form filler that automatically extracts form fields, applies semantic mapping, and completes up to 100 pages of complex layouts in 25–60 seconds. It supports batch processing via CSV uploads, auto‑filling from prior form versions, and conversion of flat, scanned, or image documents into fillable PDFs.

The platform offers multi‑tenant workspace isolation, AES field‑level encryption, two‑factor authentication, and stateless processing that deletes files immediately after completion. An API and webhook integration enable automated workflows with tools such as N8N and custom enterprise systems.
