I built a free Chrome extension that drops your saved prompts into any text box with //

I found myself typing the same prompts into ChatGPT and Claude over and over. Rewording them slightly each time. Losing track of which version worked.

So I built Promptbar — a Chrome extension that lets you save your own prompts and insert any of them into any text box on any page by typing //.

How it works:

Type // in any text box (ChatGPT, Claude, Gemini, a support ticket, anywhere)
Pick a saved prompt from the list
The text lands in the box

You can use {{variables}} inside a prompt, so one saved template covers many variations without editing it each time.

Everything is stored locally. No account, no sign-up, no cloud, no AI service of its own — it only inserts text you wrote.

One thing to know upfront: it needs broad host permissions to make the // trigger work on any page. That's a real trade-off. Nothing is collected or transmitted — the data never leaves your browser — but I know that's the first question, so I'm answering it here.

It's free. No paid tier exists today.

I'm a designer, not an engineer — this was built with a lot of AI help. Happy to answer anything about what it does or why it works the way it does.
