Chrome extension
Prompt packs in Chrome's side panel
Save one-off prompts, fill reusable variables, and copy rendered prompts without sending prompt content through a server.Version 0.2.1 is the first public Chrome Web Store release.
- Side-panel workspace
- Chrome local storage
- Variable-filled prompt output
- One-off prompt storage
PromptPack Studio is now scoped to the Chrome extension. It gives one-off and repeatable AI prompts a small local workspace: save the prompt, define the fields that change, fill values, and copy the finished prompt when it is time to use it.
Chrome side-panel workflow
Install PromptPack Studio from the Chrome Web Store.
The extension opens in Chrome's side panel so prompt packs can stay close to the browser work where they are used. PromptPack Studio keeps the scope intentionally narrow: extension-managed storage, local editing, quick-fill variables, and copy output.
It is an extension rather than a page on this site because the side panel can sit beside the tab you are working in, and a web page has to be the tab — a prompt library hosted on graysond.xyz would mean navigating away from the work every time you needed it. The storage difference matters more. Extension storage lives in the browser profile rather than in a website's origin, so saved packs survive the routine clear-site-data sweep that wipes anything a page stored, and this site has no mechanism to read them.
What it does
- Save one-off prompts and named prompt packs in the browser profile.
- Mark reusable variables with
{{variable_name}}. - Fill variables without changing the underlying prompt structure.
- Copy rendered prompts into an AI chat, document, ticket, or operations note.
- Keep saved prompts managed inside the extension UI.
Why I built it
Many AI workflows start as a surprisingly good prompt buried in a chat thread. A week later, the exact phrasing is gone, the assumptions are unclear, and the next version is worse. PromptPack is an early model for treating good prompts like small products, not a finished platform claim.
Local privacy boundary
PromptPack Studio stores prompt pack names, templates, variable names, and fill values in Chrome local storage on the user's browser profile. It does not require an account, does not read web pages, does not use content scripts, and does not send prompt content to graysond.xyz, analytics services, AI providers, or other remote services.
That privacy boundary describes what the extension's code does: it contains no path that uploads or remotely processes prompt content. Its manifest matches that implementation with only sidePanel and storage, no host permissions, and no content scripts; the whole permission set is visible on the Web Store listing before anyone installs it.
The full privacy policy is available at PromptPack Studio privacy.
Good fit
PromptPack is useful when a prompt has become a repeatable process: support handoffs, research briefs, department-specific AI instructions, review checklists, and other structured requests where the same frame is reused with different inputs.
Extension boundary
PromptPack Studio keeps saved prompts inside the extension's storage layer; it does not create separate prompt-tool files on the public website. Saved prompts stay there until you copy the prompt text into another tool.
Limits
PromptPack packages the prompt structure. It does not judge the quality of an AI model's answer, replace source review, or remove the need for privacy controls around sensitive prompts.
