## Overview

Instafill is an AI form filler for PDF and Word documents: upload any form, and it reads every field, pulls the answers from the data you already have and returns a completed document, in sessions the vendor describes as taking 25-60 seconds. Field filling uses LLM-based extraction with semantic mapping, and each field shows an explanation of its source so you can check results in a visual PDF editor before exporting. It can autofill from documents, emails and profiles, prefill from a previous version of the same form, extract structured table and list data, and fill .docx templates. Instafill reports more than 44,000 forms filled at 98.2% accuracy, states that your data is never used to train AI models, and provides enterprise controls such as field-level AES encryption, workspace isolation and data residency. It also connects to tools via a REST API, an MCP server for Claude and ChatGPT, n8n and Zapier.
