Why MEPSub?

Before vs after.

😩 Without MEPSub

❌ Searching forums and outdated manuals for answers
❌ Generic ChatGPT doesn't understand MEP specifics
❌ One AI model for everything — too slow or too shallow
❌ No conversation history between sessions
❌ Can't draft project documents from a chat interface
