PromptGuard is a desktop productivity tool concept that protects long prompts from being lost during AI-assisted work.
The problem
People often write long prompts and lose them due to crashes, browser errors, accidental refreshes, or failed submissions. The effort invested in crafting a detailed prompt is lost, and the user has to start over.
The solution
A native desktop tool that captures, saves, and protects prompts while users work across web, CLI, and desktop apps. The tool runs locally, stores data on the device, and provides a searchable archive of past prompts.
Core features
- Manual prompt capture – Save prompts with a keyboard shortcut.
- Optional automatic capture – Detect and save prompts in supported apps.
- Local-first storage – All data stays on your device.
- Prompt history – Browse and search past prompts.
- Searchable archive – Find prompts by content, date, or source.
- Native macOS experience – Designed for the macOS environment.
