Your best AI prompts, finally an asset.
Your prompts, rules and instructions are scattered across Cursor, Claude Code, Codex and a dozen Markdown files. PromptsJar turns them into a searchable, versioned library — synced to your account and ready from any browser.

Your best prompt always disappears right when you need it
It lives somewhere between a ChatGPT thread, a .cursorrules file and a Markdown note you'll never open again. So you rewrite it from scratch — and lose the version that actually worked.
Prompts scattered everywhere
Chat threads, rules files, gists and notes. No single place to look.
Rewrite the same prompt again
The version that worked last month is gone, so you start over.
Leak a key into a chat
A stray API key or .env line slips straight into an AI tool.
Everything your prompts need to become assets
- Save every prompt with tags, scene, tool and model. Lightning-fast full-text search brings back the exact prompt that worked last month in seconds.
- Every edit is saved automatically. Compare two versions side by side, restore an older one, add change notes and mark the best version per model — it's Git for your prompts.
- Turn a one-off prompt into a reusable template with {{variables}}. Add defaults and descriptions, fill them once, and generate the final prompt — ready to paste into any tool.
“PromptsJar isn't a prompt bookmark folder. version control, a workflow library and Prompt Studio for the prompts you actually reuse.”

- No idea which version actually worked
- Prompts trapped inside a single tool
With PromptsJar
- Search one library in seconds
- Reuse templates with {{variables}}
- Version history with diff and rollback
- Prompt Studio for AI-assisted drafting
- Works across Cursor, Claude Code & Codex
