ChatGPT Is Powerful — But It Doesn't Know Your Team

Custom instructions have a character limit

ChatGPT's custom instructions maxes out at a few hundred words. Your team's full knowledge base — coding standards, brand voice, product context — can't fit. You're always leaving out critical information.

Custom instructions are per-person

Each teammate sets their own custom instructions. One person's version is outdated. Another person's is missing key context. A third person hasn't set anything up. Inconsistent AI, inconsistent results.

Context is lost between every session

Close the chat and start fresh. Your product terminology, your brand voice, your architecture decisions — gone. Re-explain everything tomorrow. And the day after. And the day after that.

No way to update context for the whole team at once

Your brand guidelines changed. Now you need to tell every teammate to update their custom instructions manually. Some will. Most won't. Your AI outputs drift further from your actual standards.
