Prompts are kept in this browser's storage on your device. Nothing is uploaded, and there's no account.
How variables work
Anything in double braces becomes a field to fill in: {{customer}}, {{topic}}, {{word_count}}. Give a variable a default with a bar, like {{tone|friendly}}; the default is used whenever the field is left empty. Using the same variable twice fills both places at once.
Versions
Each time you save a changed prompt it becomes a new version, with an optional note about what changed. Pick an older version from the list to read it, fill it in or copy it. Saving while an older version is open makes it the newest version again, so nothing is ever overwritten.
Questions
Where are my prompts stored?
In your browser's local storage on this device. They stay after you close the tab, but clearing site data removes them. Use Export all now and then to keep a backup file.
Can I move my library to another computer?
Yes. Export all downloads one JSON file with every prompt and version. Open the tool on the other computer and use Import JSON. Prompts that already exist are merged, keeping every version from both.
What can I import?
A file exported from this tool, or any JSON list of objects with a title or name and the prompt text in a field called prompt, body, text or content.
Does it work with any AI tool?
Yes. The filled prompt is plain text, so you can paste it into any chat assistant or API.
