CHROME EXTENSION

Chrome extensionComing soon

Your AI prompts and site locale, one extension

AI Pier Kit turns your AI prompts into a portable library: type ~ in any input box on any site to pick and insert one. It can also override timezone and language for the sites you choose — every other site stays untouched. Data syncs through your Google account, local-first, works offline.

Prompt library: tags, search, favorites

Three things it does well

A prompt library that's always at hand

Save, organize, and search prompts in the side panel; right-click any selection to save it as a prompt; type ~ in any input box to pick one and insert with Enter.

Per-site timezone & language

Set timezone, language, and the Accept-Language header for specific sites only. The page sees exactly the locale you chose — every other site and your browser's global settings stay untouched.

Sync across devices, local-first

Data lives in your browser first and syncs to the cloud through your Google account after changes settle. Sign in on a new device to restore everything; everything works offline either way.

FAQ

Is it free?

Yes. No ads, no in-app purchases.

Where does my prompt data live?

Local-first: data stays in your own browser. Only when you turn on sync does it upload through your Google account — our server exists solely for your own multi-device sync, with no analytics or sharing.

Does the per-site timezone/language affect other sites?

No. Overrides apply only to sites you explicitly added. Other sites and your browser's global settings are never touched; you can disable or delete a site's config anytime.

When will it be on the Chrome Web Store?

It's being prepared for release. Once approved, the install button on this page will point straight to the store listing.
