Neutral by design
Draft outside any single AI platform, then copy the result into the external service you choose.
Prompt Whiteboard for macOS
A whiteboard for the AI prompt you are working on right now.
When you work across multiple AI tools, keep the current prompt in one neutral Mac space. Revise it, copy it, send it, and move on.
No prompt library. No archive pressure. No management.
Not another prompt manager.
Most prompt tools help you save, tag, sort, and revisit every prompt. Prompt Whiteboard is built for the moment before you send: the messy, useful, temporary space where the prompt gets better.
No Management
No folders, tags, prompt vaults, or automatic archive of every experiment. Use it like a real whiteboard.
Local-first
Drafts, preferences, and workspace state stay on your Mac unless you choose to copy, save, or open an external service.
The product stance
Prompt tools are becoming libraries. This stays a whiteboard.
Not every prompt needs to become an asset. Many prompts are temporary thinking space for the task in front of you.
- Edit the current prompt without turning it into a permanent note.
- Try the same instruction across multiple AI tools without being locked into one platform.
- Use structured templates as a starting point, not as a storage system.
- Clear the board when the job is done.
