Hello there,

I’ve been working on PromptJam, a browser-based workspace that lets several people craft and iterate on LLM prompts in real time. More like pair-programming than solo prompt hacking.

Why it might be useful Live collaboration speeds up the trial-and-error cycle.

Real-time multi-cursor editing, watch teammates’ edits as they happen and avoid the endless copy-paste loop across Slack or Docs.

Side-channel chat so you can discuss strategy without muddling the main model conversation.

Current state Private beta opened today. The core flow works, but I need feedback on UX pain points and real-world team workflows.

If you’re interested in kicking the tires (or telling me why this shouldn’t exist), you can grab early access here: https://promptjam.com

All comments, bug reports, and critiques welcome.

thanks!
