Prompts are living
documents.
PromptBase stores them. Notion organizes them. closedNote is the only tool that remembers how they evolved — every draft, every edit, every version.

The gap
Every tool stores prompts.
None of them remember.
PromptBase / FlowGPT
Built for sharing, not crafting
Great marketplaces for discovering prompts. But your prompts are public by default, and there's no memory of how they were built. When something stops working, you're starting from scratch.
Notion / Notes apps
Flexible but completely dumb
Notion doesn't know a prompt from a grocery list. No AI awareness, no refinement, no version tracking. You're just storing text with extra friction.
closedNote
Private, versioned, intelligent
Your prompts stay yours. Every edit is tracked with a visual diff. Iterate with AI refinement, import with OCR, and always know how you got to the version that works.
How we stack up
Built different.
| Feature | closedNote |
|---|---|
| Version history & diff view | |
| Private by default | |
| AI prompt refinement | |
| OCR — import from screenshots | |
| Prompt chaining | |
| Built specifically for prompts |
Git for your prompts.
Every time you save an edit, closedNote snapshots the version. Jump back to any point in time, see exactly what changed line-by-line, and restore with one click — without overwriting your history.
- Full version timeline on every prompt
- Visual diff — green added, red removed
- Restore any version without losing history
- No bloat — only versions when content changes
Everything included
One tool. Everything you need.
Version History
NEWEvery edit is tracked. See exactly what changed between drafts with a visual diff, and restore any previous version in one click.
AI Refinement
Paste a rough idea and let AI restructure it into a clean, reusable prompt — using your own API key.
OCR Import
Photograph a whiteboard, screenshot a chat, or upload any image — closedNote extracts the text and saves it as a prompt.
Prompt Chains
String prompts together into multi-step workflows. Output from one step feeds directly into the next.
Your prompts deserve better.
Stop losing great drafts. Start building a prompt library that actually remembers how it was built.
