RECIPES
Teach the tricky part.
A custom dropdown needs a click before a selection? Save those steps as a Recipe and let the next fill follow them.

YOUR FORM. YOUR PLAYBOOK.
Set it up once.
Make it an Action.
Choose a form, review its field map, and customize the values that matter. Preview the fill, then save an Action for the next test.
- Show the Action on matching pages
- Scope it to the form you want
- Add steps and matching Recipes
Optional on-device AI helps with the starting map. Your saved Action runs without a model.

Meet a more capable filler.
From familiar inputs to the controls that need a little teaching.

EVERYDAY TESTING
Keep the details
under control.
01Repeat fill
Repeat the same test.
Restore the last fill on the same page, even after a reload. Keep the same values while you reproduce a bug.
For stable, supported fields during your browser session.
02Precise scope
Focus on one form.
Fill the whole page, choose a named form, or fill just the focused field. Keep the rest of the page out of your way.
Keyboard shortcuts are configurable in Chrome.
03Field rules
Keep the values you need.
Match fields by their label, name, ID, placeholder, or autocomplete attribute. Reuse fixed values or data generators.
Keep the coupon set to SAVE20 while generating fresh customer details.
Scope rules to a site and organize them by Profile.
04Regional data
Test beyond one locale.
Generate data in locales including English, Hindi, and French, or let the page and browser language guide it.
Review generated values against your own validation.
05Stripe test Actions
Check both payment paths.
Choose a success or declined-card Action on supported Stripe Checkout Sessions and Payment Links.
- Successful payment
- Declined card
For Stripe test mode, using test payment details.

Add FillMatic from the Chrome Web Store, then pin it in your extensions menu.
- 2
Open a form.
Start with our signup demo or a page you're testing. You're in control of when filling starts.

Fill. Inspect. Carry on.

Do I need AI to use it?
No. One-click autofill, reusable Actions, and many more features work without AI. Optional AI assistance uses Chrome's on-device model to help build Actions. Availability depends on Chrome and your device; a model download may be required.
Will it work with my forms?
It supports standard form fields, custom controls, rich-text editors, and many more. Compatibility depends on the control, so the demos are a good place to start. File inputs, closed Shadow DOM, and browser-owned pages are not supported.
Can I control the data and filling behavior?
Yes. Customize your test data with Field Rules, save repeatable workflows as Actions, and keep project setups separate with Profiles. Settings includes typing speed, ignored fields, and many more options.
What stays on my device?
Form inspection, data generation, and optional AI mapping run locally. Settings, Profiles, Actions, and Recipes are stored in Chrome. Repeat-fill values last for the browser session.
Why does the extension need page access?
Page access lets it find fields and fill supported forms across frames when you ask it to. Use it on pages you own or are authorized to test. Saved Actions fill child frames only when you opt in; the Action builder scans and previews the main page.
