ChatGPT and Claude Created Our 500-Prompt Library — Now Everyone Writes Like Our Best Writer
James’s team sucked at AI. Same ChatGPT software, wildly different outputs. Then ChatGPT and Claude AI built a prompt library. Now the intern writes like the senior strategist. Team productivity tripled.
The problem was obvious: Give ten people ChatGPT, get ten quality levels. The senior copywriter got gold. The account manager got garbage. Everyone had access to the same AI, but nobody knew how to use it.
James tried training sessions. Created guides. Held workshops. Nothing worked. People would revert to “write me a blog post” within days.
Then James had ChatGPT and Claude build the prompts FOR the team. Not templates—complete, tested, ready-to-run prompts for every situation. Six months later, 500+ prompts in the library, team productivity up 10X, and clients can’t tell who wrote what.
The Team Inequality Problem
Before the library:
- Sarah (Senior): Amazing outputs, clients loved
- Mike (Mid-level): Decent but needed editing
- Jennifer (Junior): Unusable, required rewrites
- Tom (Account): Didn’t even try anymore
- Lisa (Design): Afraid to touch ChatGPT
Same tool. Completely different results. Clients noticed.

Your Team’s Potential Is Locked
James unlocked 10X productivity by giving everyone the same prompt superpowers. Not through training—through a library.
Your team has the same AI access. They’re getting different results. That’s fixable.
500 prompts sounds overwhelming. Start with 10. Then 50. Then watch your worst performer start sounding like your best.
The library builds itself. ChatGPT and Claude want to help. Your team wants to improve.
The only barrier is starting. Everything else is automatic.
