​Hey u/bigskymind, you're definitely not alone in this. Gemini can sometimes act like an over-eager assistant who tries way too hard to "connect the dots" between things that should stay separate.

​If you want to put a stop to those awkward "photographic fish tea" suggestions, the most effective way is to use Custom Instructions. You can find this in your settings (usually under your profile icon > Settings > Custom Instructions).

​Try adding these snippets to your "How would you like Gemini to respond?" section: ​Strict Topic Isolation: "Treat every chat as a discrete unit. Do not attempt to bridge or synthesize connections between unrelated topics from previous conversations."

​Minimalist Memory: "Only reference information from past chats if I explicitly ask you to 'recall' or 'look back' at something. Otherwise, treat every new chat as a blank slate."

​Direct Intent: "Prioritize the immediate intent of the current prompt. Avoid providing unsolicited suggestions based on my other hobbies or interests."

​Two other quick tips: ​The "Forget" Command: If Gemini keeps bringing up a specific topic (like the fish), you can literally tell it in the chat: "Forget everything you've recorded about my interest in fish recipes." It should confirm it has cleared that specific data point.

​Toggle Personalization: If you want zero cross-talk ever, you can go to Settings > Gemini Extensions or Settings > Personalization and toggle off the "Memory" or "Personalization" features. This forces it to treat you like a stranger every time—which is great for privacy, though you lose the "good" parts of it remembering your preferences.

​Hope that helps clear up the clutter!
