Frequently asked questions

How does PromptPilot work?

PromptPilot uses Gemini Nano – Google's on-device AI built into Chrome – to improve, structure, and expand prompts directly in your browser. All processing happens on your device, with no external servers involved.

Why does PromptPilot only work in Chrome?

Gemini Nano is a Chrome-exclusive feature and is currently only available in Google Chrome version 127 and above. Other browsers such as Brave, Firefox, or Safari do not support this API.

What are the hardware requirements?

Gemini Nano requires at least 16 GB of RAM and 4 GB of VRAM. When you first activate the extension, Chrome will download the AI model – this may take a few minutes.

Are my texts sent to any servers?

No. All AI processing runs locally via Gemini Nano on your device. Prompt content is never sent to external servers. PromptPilot does not transmit any user data.

Can I use PromptPilot on iPad or mobile?

No. Chrome Extensions are not available on mobile devices, including iPads. PromptPilot is designed exclusively for Chrome on desktop (Windows, Mac, Linux).

Important notes

  • PromptPilot requires Google Chrome – other browsers are not supported.

What data the extension processes

PromptPilot processes only text that users actively enter into the extension or that is selected in an active tab. Processing is done locally via Chrome's Gemini Nano API.

Input text is passed to Chrome's local LanguageModel API and processed directly on the device. No data is transmitted to external servers. No content is permanently stored.

Transfer to third parties

No user data or prompt content is transmitted to the developer's own servers or to any third parties. PromptPilot does not establish connections to any external services.

Website content and active tabs

On explicit user action, the extension can import selected text from a webpage. There is no automatic access to browsing history, no background analysis of websites, and no user profiling.
