Your AI Prompt Library,
Everywhere You Work
Most prompt tools are built for teams and pipelines. PromptNote is a lightweight notebook for iterating on prompts — with versioning, tags, and access from your browser, terminal, Raycast, and AI agents.
How it works
One prompt, many versions, zero friction.
One note = one prompt idea
Keep variants together, not scattered across files and chat windows.
Add versions as you iterate
Every tweak is saved as a new snippet. Never lose the version that worked.
Compare differences
