I turned off Gemini Personal Intelligence for a week — and I’m not going back

I’m usually first in line to test new AI features, especially the ones that promise to make life easier. Memory tools, connected apps, personalized suggestions and similar tools sound great in theory because they promise to make assistants smarter by learning how you work. And while I love ChatGPT memory, Gemini Personal Intelligence was just so wildly different.

For those who haven't tried it yet, Gemini Personal Intelligence is a feature designed to use your history, preferences, even your Gmail, Google Docs and Google Photos to deliver more tailored responses.

It sounded helpful. In practice, it became distracting and created more problems than productivity. After using it for a while, I noticed a pattern: Gemini would pull personal context into responses where it simply didn’t belong. Here's why I finally turned it off.

This wasn't a privacy fail — it was a performance fail

One reason AI users opt out of Personal Intelligence and memory mode is because they are worried about AI having access to everything from email to files. A lot of criticism around personalized AI focuses on data collection or privacy concerns. Those are valid, but in my experience, it wasn't about a privacy fail at all, it was the way Personal Intelligence made all of my responses worse.

What's interesting, is that I didn't realize how bad the responses were until I compared them to my work Gemini account — the one that doesn't use Personal Intelligence. Depending on whether I was on my personal or work computer, I would open Gemini and ask a question. When I used my personal account, the one connected to Personal Intelligence, it would add in an element that simply didn't need to be there.

For example, if I was looking for a chicken recipe for dinner, it would say something like, "Since you will be at a book fair this September prompting your book, Nico IRL, you're going to want to save time with recipes like this one."

Huh? In other words, I’d ask a clean, unrelated question and Gemini would reach backward into previous chats, trying to connect dots that didn’t need connecting. Instead of answering the prompt in front of it, it sometimes seemed overly focused on proving how much it remembered.

This didn't happen once, it happened nearly every time until I had finally "had it" and turned it off.

This wasn't intelligence, it was an interruption

The memory feature on Gemini is great, until it's not. I do appreciate it pulling up certain information, but I don't need the AI to do it all the time. For me, that's not at all the way memory should work.

For example, with ChatGPT, I'll ask something like, "Remember when I asked you to help me write a calm letter to my child's teacher? Let's revisit that for another related incident."

ChatGPT will pull it up when asked and not try to throw it in when I'm asking about something else. And that's where the breaking point was for me with Gemini. The responses started feeling wildly off-base. Imagine asking for a simple recipe or quick idea and getting something along the lines of:

“I know you are writing another Sci-Fi book, so here’s a note to your child's teacher that you might want to put in the book.”

That’s obviously not the exact wording, but it captures the issue perfectly. Past context about a book project had nothing to do with the task at hand. Instead of helping, it felt like talking to someone who only half-listens, then changes the subject to something random they remember about you.

The result wasn’t smarter answers. It was cluttered ones. For me, good personalization should know when to stay quiet and bring up what it remembers at the right time.

When Memory mode is useful

Memory can be genuinely useful when it supports your project. For example, AI remembering your preferred writing tone, recurring tasks, formatting habits, your job, character traits or favorite tools can help so you don't have to keep reminding AI about those things.

All of those things have saved me plenty of time. But great assistants also need judgment. They need to know when past context is relevant and when it should stay in the background. That’s where this experience fell short. I found it missing the precision of Custom Instructions, where I choose what the AI knows, rather than letting the AI guess based on everything I've ever said.

What changed after I turned it off

Once I disabled Personal Intelligence, responses felt cleaner almost immediately. Gemini was more focused on the current prompt. It stopped trying to weave in old details from unrelated chats. Brainstorming felt less boxed in, and straightforward questions got straightforward answers.

Most importantly, I no longer felt like I had to “manage” the AI’s memory. I didn't have to phrase prompts carefully to avoid triggering an old memory. I could just ask.

But I think there is a bigger lesson here for AI tools. We've been sold the idea that more memory is an automatic upgrade and that more personalization and more context meants more relevance.

But more context only helps when it’s applied with social awareness. Otherwise, it creates a strange new problem: an AI assistant that knows everything about you, but doesn’t know what matters right now.

Bottom line

I wanted Gemini Personal Intelligence to make the assistant sharper. Instead, it created noise where there should have been clarity. When it comes to memory mode, I'm keeping ChatGPT memory, but have completely turned it off with Gemini. The takeaway here is that the best AI shouldn't just remember everything; it should have the wisdom to forget when to mention it and have the context not to bring it up unprompted. I turned it off, and honestly, I don’t miss it.
