Frequently Asked Questions

How does the AI understand different form layouts?

We use a Large Language Model to semantically analyze the DOM structure and labels of a web page. It doesn't look for specific ID names; it understands the intent of the field.

Is my OpenAI API key safe?

Absolutely. Your key is stored locally in your browser using encrypted storage. It is never transmitted to our servers.

Which browsers are supported?

Chrome, Brave, Edge, and any Chromium-based browser. Firefox and Safari support is on our roadmap.

Can I use OpenRouter instead of OpenAI?

Yes. FormFill AI supports OpenRouter as a fully integrated alternative. Sign in with your OpenRouter account directly via OAuth — no manual API key management needed. This gives you instant access to models like Claude 3.5, Gemini 1.5, and Llama 3.
