Frequently asked questions

Is PromptKit really free?

Yes, completely free. No premium plan, no trial period, no credit card. We built this as a productivity tool to help our community.

Do my prompts sync across devices?

PromptKit uses Chrome's built-in sync storage, so your prompts automatically sync across all Chrome browsers where you're signed in.

Is my data private?

100%. All prompts are stored locally in your browser (Chrome storage). We have no servers, no analytics on your data, no account system.

What are {{variables}}?

You can write prompts with placeholders like {{product_name}}. When you click the prompt, PromptKit shows a form to fill in those values before injecting.

Does it work with the free ChatGPT plan?

Yes. PromptKit works with any ChatGPT tier — free, Plus, or Team. Same for all other supported platforms.
