Tips for better prompts

Be specific about the task. "Write three subject lines under 60 characters" beats "help with my email".
Give the context the AI can't guess: who it is for, what has been tried, and what good looks like.
Say the format you want so the answer is ready to paste.
One example is worth a paragraph of rules.
For long documents, put the document first and your question at the end.

Any chat model: ChatGPT, Claude, Gemini, Grok, Llama and others. The XML style suits Claude well; Markdown and plain text work everywhere.

A clear task, the context the model can't guess, the audience, the output format and any hard rules. One good example helps a lot.

No. The builder runs in your browser and nothing you type leaves your device.

Yes. Paste the Role, Rules and Tone parts into a system prompt and keep the Task for each message. For agents, try the agent setup generator.
