prompt-xTHE WORKSPACE FOR NEXT-GEN BUILDERS
Prompts are like code.
Manage them like code.
Structure prompts in 9 semantic fields. Compile for Claude, GPT-4, and Gemini. Launch with one click.
Start free.
Your prompts are your best asset.
There is a way to make it better.
Scattered across docs, Slack, Notion and code comments
Now prompts are treated like code.
Manual reformatting every time you switch platforms
Claude needs XML, GPT wants Markdown.
No way to measure if a prompt is actually good
Quality should be numeric, not vibed.
Everything prompt engineers need.
Write once, compile everywhere
Same prompt, perfect formatting. XML for Claude, Markdown for GPT-4, uppercase labels for Gemini. Switch platforms without re-editing.
5 target platforms
Structure, not guesswork
Nine semantic fields — Role, Context, Task, and six more — guide every prompt. Consistent structure whether you write 3 fields or 9.
