Open Autofill

Automatic form filling. Less typing, even for the extra questions.

Open Autofill is a free automatic form filler for Chrome. Save your usual answers once, then let matching fields fill automatically. It also remembers site-specific answers, dropdown selections, and checkbox choices that ordinary browser autofill misses.

Always free. No daily limit. No account or cloud sync. Your saved answers stay in your Chrome profile.

Remember more than your address

Your usual answers, ready to fill

Save names, email, address, phone, birthday, and other frequently used details. Open Autofill fills matching fields when you open a form, while preserving answers you already typed and nonempty page defaults.

Different answers for different forms

Change an answer normally. With Auto-learn on, the correction is remembered for that exact site and form. Your usual answers stay unchanged everywhere else.

Extra questions and choices

Remember answers beyond contact details, including dropdowns and checkbox choices. Checked and unchecked choices both matter. Clear a field to remember that it should stay blank next time.

Local memory, under your control

Ignore sites, forget their saved answers, or export a JSON backup to your computer. Restoring a backup previews what will be replaced and asks for confirmation. No analytics or external AI services.

Get started in Chrome

  1. Install Open Autofill from the Chrome Web Store and pin it to your toolbar.
  2. Open the extension, enable form memory, and enter Your usual answers.
  3. Visit a form. Matching fields fill automatically.
  4. Correct an answer with Auto-learn on, or choose Save extra answers to save answers for your next visit.

Use it for repeated registration forms, applications, and everyday details you are tired of retyping. You stay in charge of reviewing and submitting the form.

Privacy and safety, without a cloud account

Your saved answers stay locally in this Chrome profile. Open Autofill does not upload them, collect analytics, or sell data. You can inspect the open-source code and read the privacy policy.

Passwords, payment card details, CVV, Social Security numbers, and one-time codes are not filled. Open Autofill does not solve CAPTCHAs or submit forms automatically. Search boxes are skipped by default.

Local storage does not hide filled answers from a website. Website scripts can read those values before you submit. Ignore sites where you do not want automatic filling. Exported backups contain readable personal data, so keep them somewhere private.

Frequently asked questions

How is this different from Chrome's built-in autofill?

Open Autofill adds local memory for extra form questions and site-specific corrections, alongside your usual contact details. Different forms can keep different answers without changing your defaults.

Is Open Autofill really free?

Yes. There is no daily filling limit, paid tier, or account requirement.

Does it work on every form?

No. Some custom controls and forms may not fill. If a website changes its questions or form structure, you may need to save an answer again. Review filled answers before submitting.

Can I move my saved answers to another computer?

Export a JSON backup and import it into Open Autofill in the other Chrome profile. There is no automatic cloud sync. Import replaces existing memory after a preview and confirmation.

Where can I report a problem or suggest a feature?

Use GitHub issues. Describe the form and what happened, without posting personal answers or private backup files.
