A Simple Notebook for
AI Prompts — with Versions
Most prompt tools are built for teams and pipelines. PromptNote is a calm, lightweight notebook for iterating on prompts across writing, research, code, and images.
Why PromptNote exists
- Use Clipboard managers? They sort by time, so your prompt variants get buried and lost in chaos.
- Use Notes apps? They become long, messy documents where it's hard to compare versions.
- Use Dev tools? Complex pipelines are overkill when you just want to tweak a Midjourney prompt.
How it works
Simple by design.
One note = one prompt idea
Keep variants together, not scattered across files.
Every edit is a version
Never lose a "better" version you had 5 minutes ago.
