System prompt builder
Sida loo isticmaalo System prompt builder
System prompt builder assembles a reusable instruction block that defines an assistant's role, audience, tone, boundaries and expected output. Enter the assistant's main job as the task, adjust the five fields, and get plain text with each part under its own heading plus a closing quality check that asks for stated assumptions and uncertainty.
- Paste the source into the input editor, or load the built-in example.
- Adjust the basic settings, then open Advanced mode for export and fine-tuning options. Custom settings stay active when the panel is closed.
- Run system prompt builder, review the output, then use the available copy or download controls.

Su’aalaha badanaa la isweydiiyo
How do I set boundaries in a system prompt?
Put rules in the Constraints field, one per line if you like, such as topics to decline or sources to rely on. The text is placed verbatim under a Constraints heading, so write it as direct instructions addressed to the assistant.
What sections does the generated system prompt contain?
Role, Task, Audience, Tone, Constraints, Output format and Quality check, in that order. Your main input fills Task, the five settings fill their matching sections, and the Quality check wording is fixed by the template.
Can I save the system prompt as a file?
Yes. Besides copying, you can download the result as system-prompt.txt, a plain text file containing exactly the generated sections. That makes it easy to paste into an assistant's custom instructions or keep alongside your project files.
