AI Form Filling Assistant for Chrome
Automate tedious form filling with Prophet. The AI agent can read, understand, and fill out web forms on any site using browser automation tools.
Why form filling slows you down today
Filling out repetitive online forms with the same information across different websites is a monotonous time drain.
Complex application forms with dozens of fields require careful attention to ensure every field is completed correctly.
Job applications, government forms, and insurance paperwork often ask for the same information in slightly different formats.
Reviewing and correcting auto-filled data that browser password managers get wrong takes almost as long as filling the form manually.
How Prophet changes form filling
Uses browser automation to read form fields and fill them with appropriate content based on your instructions.
Understands form context and field labels to populate the correct information in each input, dropdown, and checkbox.
Navigates multi-step forms by clicking through pages and filling each step sequentially using the agent loop.
Reviews completed forms before submission, allowing you to verify all entries and make corrections.
What Prophet actually does for form filling
Prophet is not a chat box that reads pasted text. It works against the live page through Chrome, using the same browser tools every time. Here is the sequence for form filling, and the tools it calls at each stage.
1. Maps every field on the form
Prophet snapshots the form and identifies each input by its label, type, and required state before touching anything.

Values are written to specific elements rather than simulated keystrokes, so dropdowns, radio groups, and hidden fields behave correctly.

It submits a step, waits for the next page to render, and continues — useful for job applications and long onboarding flows.

Open the Prophet side panel on a page where you would normally do form filling by hand, then paste one of these in.
“Fill out this contact form with my name John Smith, email john@example.com, and a professional inquiry message.”
“Complete this job application form with the information from my resume summary.”
“Navigate through this multi-page registration form and fill in all required fields.”
“Review this completed form and check if any required fields are missing or incorrectly filled.”
“Fill out the shipping address section with my standard delivery address.”
