An AI extension that reads pages, fills forms, and handles multi-step flows. Every action verified. Works on any web form.
Designed for anyone who fills a lot of web forms — researchers, testers, applicants, registrants.
Understands the current page, visible interactive elements, form structure, and layout — including elements inside iframes and shadow roots.
Clicks buttons, links, tabs, menus, and controls. Types into text fields, text areas, and all native inputs including dates, numbers, emails, and URLs.
Handles radio buttons, checkboxes, dropdowns, sliders, matrices, ranking controls, autocomplete fields, and multi-page flows across applications, registrations, and tests.
Inspects forms before advancing and reports which required or invalid fields are still incomplete — no more accidentally submitting half-finished applications.
Detects when clicks produce no progress, actions error out, or the same interaction is requested repeatedly. Adapts behavior in real time across different form types.
Doesn't blindly reuse old element references. If a control moves after a page change, it finds and updates the target automatically.
If a form can throw it at you, FormPlane can handle it.
Every action is verified before the agent trusts it. No guessing. No hallucinating clicks.
Checkbox clicks verify the checked state. Dropdown selections verify the selected option. Text input verifies the page retained the entered value. Slider actions verify the resulting numeric value.
Before clicking Next, Continue, or Submit, the agent checks for invalid fields, missing required inputs, and incomplete sections. No more accidentally submitting half-finished forms.
Password and file values are excluded from page summaries. The agent avoids inventing personal answers and asks for missing information instead of guessing.
If the page changes, the agent checks URL, tab, XPath, tag type, ID, name, role, label, and iframe location. If a control moved, it finds the new reference — or stops and asks if it's ambiguous.
Detects when actions return errors, clicks produce no progress, or the same interaction is requested on an unchanged control. Learns from form behavior during and across tasks.
Recognizes when the agent repeatedly tries to advance without resolving validation errors, or when the page remains unchanged after an interaction. Stops and escalates instead of looping.
