Terms of Service

Last updated: 11 November 2026

These terms apply when you use the PromptFill website, the PromptFill Chrome extension and the Pro plan (together, “PromptFill”). By installing the extension or subscribing to Pro, you agree to them. If you do not agree, do not use PromptFill.

What PromptFill is

PromptFill is a tool for developers and QA testers. The free Chrome extension fills web forms with realistic test data. The Pro plan adds AI-powered form filling and an MCP server that lets AI assistants such as Claude or Cursor fill forms in your browser.

Using PromptFill responsibly

PromptFill is made for testing forms on websites and apps that you build, test, or have permission to test. You agree not to use it to:

• submit false information where that is unlawful or deceptive;
• create fake accounts, reviews or orders, or send spam;
• break the terms of the websites you use it on;
• interfere with PromptFill, or get around the limits of your plan.

The data PromptFill generates is made up. Any resemblance to a real person, company or address is a coincidence. You are responsible for what you submit with it.

The Pro plan

Pro is a paid subscription. Pricing is coming soon and will be shown on this website before you subscribe. A subscription renews automatically at the end of each period until you cancel.

You can cancel at any time. Cancelling stops future renewals, and Pro stays active until the end of the period you have already paid for. If you think you were charged in error, contact us and we will look into it. If we change the price, we will tell you before your next renewal.

AI features

AI fill writes values using an AI model. The results can be wrong or unsuitable, so check them before you rely on them. Do not use AI fill on forms that contain information you are not allowed to share with a third-party service.

Our rights in PromptFill

We own PromptFill, including its software, name and design. We give you a personal, non-exclusive, non-transferable right to use it under these terms. You may not copy, resell or reverse engineer it, except where the law allows.

Availability and changes

We work to keep PromptFill running, but we do not promise it will always be available or free of errors. We may change or remove features. If we stop offering Pro, we will not charge you for any period after it ends.

Ending your use

You can stop using PromptFill at any time by removing the extension and cancelling Pro. We may suspend or end your access if you break these terms.

No warranty and limits on liability

PromptFill is provided “as is”, without warranties of any kind, to the extent the law allows. We are not liable for indirect or consequential loss, or for lost data, profit or business. Our total liability to you is limited to the amount you paid us in the 12 months before the claim. Nothing in these terms limits liability that cannot be limited by law, or removes rights you have as a consumer.

Changes to these terms

We may update these terms. When we do, we will change the date at the top of this page. If a change is significant, we will give Pro subscribers notice before it takes effect. Continuing to use PromptFill after a change means you accept the new terms.
