The upgrades being pushed out for AI chatbots arent slowing down, and one of the latest improvements added to Google Gemini is an ability for the AI to remember previous conversations. This allows you to refer back to something youve said the previous day, the previous week, or whenever it was. But do you want that?Gemini can now recall your past chats to provide more helpful responses, explains Google. Whether youre asking a question about something youve already discussed, or asking Gemini to summarize a previous conversation, Gemini now uses information from relevant chats to craft a response.For now, this is exclusive to Gemini Advanced subscribers and those using Gemini in English, though it may roll out to other users in the future. The new memory feature is enabled by default, though you do have some options if you dont want the AI bot remembering everything youve said.How Geminis memory worksConversation history works on top of the existing memory feature. Screenshot: Google The new upgrade is relatively straightforward: It means that chats that stack up in your Gemini app, like files in your Google Drive, can be referred back to whenever you like (ChatGPT recently launched a similar feature). The idea is that the AI will get to know you better, meaning more relevant responses and less repetition.For example, Gemini might remember the sports teams you follow, the music you like, or the hobbies you engage in. When youre asking for news updates or activity ideas, that can be useful information for the bot to havefilm recommendations can skip the titles youve watched already, for example. You dont need to switch this on, as its enabled automatically.It can also be useful for summaries. Maybe you want to summarize the days chats so far, or youve forgotten what youve already talked to Gemini about through the course of the week. You can just make a request using natural language: What were we talking about yesterday? for example, or summarize everything we chatted about last week.Based on our testing, this all works rather well, though its not perfectGemini will sometimes forget details (or more likely, pick out the wrong ones), and give you responses that make no sense. On the whole though, its a useful addition to Geminis features, as long as you dont mind keeping everything on record.Note that this is separate to the information you can tell Gemini about yourself by clicking Settings and Saved info (on the web), or by tapping your profile picture (top right) and Saved info (on mobile). This feature lets you commit key details to Geminis memory, such as what your occupation is, or the foods you like, or how youd like Gemini to respond to you (with simple, informal language, for example).How to manage Geminis memoryYou can auto-delete your Gemini chats if youd prefer. Screenshot: Google The idea of Gemini remembering everything you say to it may be raising a few red flags for you, and its worth remembering that most of the time youre using AI tools, youre also helping to train them. This is the case with Gemini, and your chats might even be reviewed by humans, in order to improve Gemini and its AI models.You can read the full Gemini Privacy policy online, and its worth noting this part of it: Please dont enter confidential information in your conversations, or any data you wouldnt want a reviewer to see or Google to use to improve our products, services and machine learning technologies.Google doesnt let you opt out of having your chats used in this way, but you can specify that the chats arent to be stored at all, or should be deleted after a certain time period. It depends how you want to balance your privacy and digital data trail against the convenience of having all your AI conversations available to review and recall.To find these options on the web, click Activity inside the Gemini app; in the mobile apps, tap your profile picture (top right), then Gemini Apps Activity. On the next screen, you can turn off the Gemini chat history altogetherwhich essentially means conversations are deleted as soon as youre done with them.You can also wipe everything thats been gathered so far, as well as erase individual chats. If youd rather have Gemini automatically delete your conversations after a certain amount of time, youre able to choose between 3 months, 18 months, or 36 months (and you still get the manual deletion options too).
