What is Instafill?

Instafill.ai is an AI form filler that completes PDF forms automatically and turns Word files, flat PDFs, and scans into fillable templates. It pulls data from whatever you already have - spreadsheets, text files, images, partially filled PDFs, and fills each field with speed and precision. Key features: - AI agent: assembles complete document packages, not just single fields - merging, stamping signatures, headers, and page numbers, placing images, flattening and splitting. - MCP server: connects Claude, ChatGPT, and Codex directly to your form library. - Windows desktop app: right-click any PDF in File Explorer and fill it without opening the app. - Batch filling: complete the same form hundreds of times from CSV or XLSX. - Reusable profiles: store client data once, reuse it across every form. - Field logic: conditionals, dependencies, and row-by-row table control. - API, webhooks, Chrome and Edge extensions.

What is Fill?

The Quickest Way to Fill Out, Send, and Sign PDFs. PDFs serve various functions, such as legal agreements, application submissions, and business contracts. Although Adobe offers a paid software solution, it tends to be costly, slow, and requires substantial storage space on your device. Alternatively, Fill is a free online PDF tool that provides a fast method for signing, completing, or dispatching forms for others to fill out and sign. With its built-in email feature, you can easily send documents directly from Fill, including a custom subject line and message for better communication. Additionally, all completed forms are securely stored in your Fill account, giving you an organized record of who signed what and when, which simplifies the process of tracking signatures. This tool enhances the efficiency of managing PDFs, ultimately saving you both time and resources, and allows for easier collaboration among users.
