What it does

What Form Filler does

Fill the form on any page in one click with sample data, your own saved values, or AI that reads the page. Your saved values are encrypted on this device.

  • Realistic sample data

    One made-up person per fill: the email matches the name, and the city, postal code and country go together.

  • Your saved values

    Save your name, email, phone, address, company and more. They replace the sample values when you fill.

  • Encrypted on this device

    Saved values are encrypted with AES-256-GCM, using a key that never leaves this device. They are left out of backups, like API keys.

  • Names that fit every form

    A saved full name also fills first and last name fields, and the other way round.

  • Safe by design

    It never fills passwords, card numbers, CVV, IBAN, one-time codes, hidden fields, file inputs or invisible trap fields, and it never submits the form.

  • Undo and settings

    Undo puts back what the fields had. In settings, skip fields that already have a value, highlight the fields it filled, and pick the AI engine.

  • Right-click menu

    Right-click a page and pick “Fill this form” or “Fill this form with AI”.

Permissions and why

Both are asked the first time you fill a form, and you can take them back in Settings › Permissions. You can take any of them back in Settings › Permissions.

  • Your data stays on your device

    Your saved values are encrypted with a key that never leaves this device, saved in the browser and left out of backups. Fills and settings stay on this device too. Saved values are never sent to the AI. No account, no analytics.

  • The AI provider you picked in Ask AI (Anthropic, OpenAI, Google or OpenRouter)

    Only with Fill with AI (Pro) on the cloud engine: the form's labels and the text near the form, sent from your browser with your own key. By default Fill with AI uses the model built into Chrome, and your data stays on your device.

FAQ

Form Filler: common questions

Does Form Filler submit the form?

No. It only fills the fields. You check them and press the button yourself, and Undo puts back what was there.

Will it fill my password or card number?

No. It skips passwords, card numbers, CVV, IBAN, one-time codes, hidden fields, file inputs and invisible trap fields.

Do my saved values go to the AI?

No. Fill with AI sees only the page title, the form's labels and the text near the form. Your saved values never go to the AI.

Is Form Filler free?

Yes, with no cap: sample data, saved values and undo are free. Winaruz Pro adds Fill with AI.
