We read every xAI Grok prompt guide so you don't have to.

What xAI Grok actually rewards

We pulled this from xAI's official guidance and what works in production. The short version:

• →Define audience and scope.
• →Ask for tools explicitly (web/X/code-execution).
• →Request multi-perspective analysis for nuanced topics.
• →For code tasks, point to specific files (@errors.ts) — avoid dumping repos.
• →Require evidence/citations for current events.

Common mistakes we fix automatically

• Avoid
  Don't ask for jailbreaks (filtered).
• Avoid
  Don't expect voice mode in non-app contexts.

Frequently asked questions

Which versions of xAI Grok does this support?

We support grok-3, grok-4, grok-4.1, grok-code-fast-1. We apply the prompt patterns xAI recommends for each, so the rewrite is tuned to the version you're using.

Is my prompt stored or used for training?

No. Prompts are sent to the rewriter, scored, returned, and discarded. We don't train on them and we don't keep them around.

Do I need to know prompt engineering to use this?

Nope. That's the point. Paste what you have, click Rewrite, get back a version that follows xAI's official guidance.

What makes this different from xAI Grok's own "improve prompt" feature?

Built-in optimizers use the model's own preferences. Ours is built on xAI's official documentation and patterns that consistently produce better results in production. xAI Grok works best with prompts in the 100-2000 token range, and we keep rewrites inside that window.
