Everything you need to set up PromptCase and keep your prompts flowing. Two capture clients, one library.

Getting started

PromptCase captures the prompts you write — never AI responses, system prompts, or tool output — and syncs them to your account. Setup takes three steps.

  1. 1

    Create an account

    Sign up free — no credit card needed. Your dashboard is where every captured prompt lands.

  2. 2

    Pick a capture client

    The CLI captures prompts you type into Claude Code. The browser extension captures prompts you submit on 13 AI chat sites. Use one or both — all plans include unlimited devices.

  3. 3

    Generate a device token and connect

    In your dashboard, open Dashboard → Devices and generate a token for your client. Paste it into the CLI or extension once — refresh is automatic after that.

CLI (Claude Code)

The promptcase CLI runs a small background daemon that captures the prompts you type into Claude Code and syncs them to your account roughly every 60 seconds. Only your own messages are captured — assistant replies, tool output, and system messages are filtered out.

Install

$ npm install -g promptcase

Requires Node.js 20 or newer.

Authenticate

$ promptcase setup

Then paste the token from /dashboard/devices/cli-token when prompted. The daemon starts automatically and keeps running in the background, including after reboots.

Commands

promptcase setupAuthenticate and start the daemon (alias of init)
promptcase statusShow auth, daemon, and sync status
promptcase syncForce a sync right now and run diagnostics
promptcase showShow recent synced prompts (-n <count> for more)
promptcase stopStop the daemon (auto-start stays for next boot)
promptcase logoutStop the daemon, revoke the token, clear credentials

promptcase init is the same command as promptcase setup — use whichever you prefer.

Package details and release notes live on npmjs.com/package/promptcase.

Browser extension

The extension captures prompts at the moment you submit them — and only the text you wrote. It works on these 13 sites:

  • ChatGPT
  • Claude
  • Gemini
  • Microsoft Copilot
  • Perplexity
  • Mistral Le Chat
  • HuggingChat
  • You.com
  • Poe
  • Grok
  • Bolt
  • Lovable
  • Replit

Firefox

  1. Install from addons.mozilla.org.
  2. Open the extension's Options page and paste the token from /dashboard/devices/extension-token.
  3. Optionally toggle capture per site under Options → Sources.

Chrome

Coming soon to the Chrome Web Store.

Managing your library

Captured prompts land in your dashboard, where you can shape them into a reusable library:

  • Tags — label prompts with as many tags as you like, then filter by them.
  • Folders — group prompts by project or topic.
  • Favorites — star your best prompts so they're one click away.
  • Search — keyword filtering across your prompts, combinable with tag, folder, source, and favorite filters.
  • Bulk actions — select multiple prompts to tag, move, or delete at once.
  • Sources view — browse prompts by where they were captured, from Claude Code to any of the 13 supported sites.

Devices & tokens

Every capture client connects with its own device token, managed from Dashboard → Devices:

  • Generate a token per device and give it a name you'll recognize ("Work laptop", "Home Firefox"). You can rename devices later.
  • Tokens are shown once. We store only a SHA-256 hash, so copy the token when it appears. If you lose it, revoke the device and generate a new one.
  • Tokens are valid for 180 days and refresh automatically while the client is in use — no re-pasting needed.
  • Revoke any device from the dashboard at any time; its tokens stop working immediately.

Troubleshooting & support

Capture isn't working on a site

  1. Check the site's toggle in Options → Sources — it may be switched off.
  2. Make sure you're signed in to the site itself; some sites render a different composer for signed-out visitors.
  3. Still stuck? Email support@promptcase.dev with the site name and your extension version (shown in Options → About).

CLI health check

$ promptcase status
$ promptcase sync

status shows auth, daemon, and sync state; sync forces an upload and runs diagnostics.

For anything else, write to support@promptcase.dev — we reply within 1–2 business days.
