Built for prompts you use more than once
- Sections and variables
- Split a prompt into Role, Task, Format or any sections you name. Use
{{team}}for the parts that change, with a hint for each one. - Copy filled prompt
- Fill in the variables and copy the finished text, or copy the template as it is. The preview shows exactly what you will paste.
- Bring your existing prompts
- Paste a prompt or import Markdown notes, such as Notion or Obsidian exports. Importing copies them once; import again to add new notes or update prompts that changed. Placeholders like [topic] become inputs, and an AI provider you connect can split a prompt into sections for you to review.
- History
- Every save keeps the previous version. Compare versions word by word and restore any of them.
- Folders, favourites and search
- Find a prompt by its name, its folder or any text inside it.
- Your library in ChatGPT and Claude
- Connect your account to ChatGPT or Claude to list, open, save and update prompts without leaving the chat.
