# Prompt builder Build a clearer instruction, then decide whether to copy it or use it in a chat. In the app this page is called **Prompt builder**. ## The pass 1. Rough Write a rough instruction and press **Sharpen**. 2. Sharpened Press **Ask me a question** to be asked clarifying questions, one at a time, with no fixed limit. Answer or skip, then review and edit the improved version. It lists what changed and the assumptions it made. 3. Use it Copy it, or send it to a chat. ## Start with a clear instruction The result is not sent until you choose to send it, unless you switch on sending without asking. It can help with instructions you want to get right before using: - A review checklist - A commit-message format - A [scheduled task](https://zerolog.ch/docs/tasks)'s instruction ## What it learns and what it costs The builder keeps short notes about your preferences, up to 40. You can read, edit and delete each one, or delete them all. Every pass runs on the everyday model against its own budget per session; when that budget is spent it stops and the text stays usable. Two switches control it: sharpen every message before it goes out, and send the sharpened version without asking. ## From rough text to a sharpened prompt Mermaid source of the diagram on this page: ```mermaid %% Prompt optimiser (Prompt builder): from rough text to a sharpened prompt.
