From reusable prompt to finished plan.
Variables, prompt ratings, boards, and diagrams stay close enough to work together without becoming one crowded tool.
Variables
Fill once. Reuse often.
Turn placeholders into a focused form, then copy the finished prompt.
Prompt rating
Remember what worked.
Keep one rating, the model, and a short note with each prompt.
Read-once agent snapshots
Share the task. Not your workspace.
Turn one finished item or diagram selection into Markdown an agent can fetch once.
- Built from the prompt, board, card, diagram, or selected nodes you choose.
- Held in server memory only and never written to a permanent library.
- Deleted after the first successful read, or after about two minutes.
Your workspace stays yours.
No login, telemetry, or permanent cloud vault. Your data moves only when you move it.
Why local-first matters- Library
- IndexedDB in this browserNo remote account or silent sync.
- Sharing
- Explicit and scopedOnly the context you choose can leave.
- Backup
- One portable fileStore it wherever you already trust.
Questions, answered.
What matters before you put your first prompt in.
Is Promptsson free, with no account?
Yes. Open the app and start using it. There is no sign-up, email, advertising, or paywall on your own prompts.
Where is my data stored?
Your library lives in IndexedDB on your device. Nothing syncs by default. Only content you explicitly open elsewhere or place in a temporary snapshot leaves the browser.
What is a temporary agent snapshot?
It is a read-only Markdown URL for one finished item or diagram selection. The first successful fetch returns the content and deletes it. The snapshot also expires after about two minutes.
Does it work with any model or coding agent?
Yes. Promptsson is model-agnostic. Copy a finished prompt into any model, or give any agent that can fetch a URL a temporary Markdown snapshot.
What if I clear my browser or switch devices?
Export your workspace as one backup file, store it wherever you choose, and import it in another browser or device.
Keep the next good prompt within reach.
Open the app. The examples are already there.
