I built a custom AI expert with Gemini — and it’s saving me time every single day

I use AI every single day, but for a long time, I kept running into the same frustrating wall.

No matter how advanced the models got, I was stuck in a loop of "re-explaining" myself. Sure, enabling memory mode helped significantly, but not everything "clicked" with the AI every time. My tone, my specific style, the exact formatting I needed — it felt like I was re-teaching Gemini every time I opened a new chat.

And while it wasn't exactly hard to type everything over, it was repetitive and frankly, a waste of time. I like using Gemini for its speed, reasoning and multimodal capabilities and often gravitate to it over ChatGPT for those very reasons. But, I've noticed its memory pales in comparison to OpenAI's. That is, until I tried something different. Instead of starting fresh with a blank chat every time, I built my own AI Expert using Google Gemini Gems.
