Formix AI

Fill online forms and PDFs instantly with a private AI autofill assistant

AI-powered intelligent autofill

Formix reads the documents and prompts you provide and predicts the correct value for each form field, filling text inputs and dropdowns automatically while you keep control.

Local-only data storage

Your input documents, prompts, and history live in your Chrome browser storage, not on a remote server, so personal details stay on your device.

Reviewable, regeneratable values

Every AI-generated value is highlighted so you can check it, and any single field can be regenerated with a reload button without redoing the whole form.

Works with web and PDF forms

Use it on job applications, shopping checkouts, classified listings, Google Forms, and PDF documents, as long as the page structure is supported.
