ChatGPT, Gemini, Claude Memory: How to Delete Stored Data
The article from t3n.de discusses the memory functions of AI chatbots ChatGPT (OpenAI), Gemini (Google), and Claude (Anthropic), explaining how these tools store personal details from conversations and use them to personalize responses. It highlights privacy concerns and provides a detailed guide on how users can access, manage, and delete this stored information. The guide includes specific prompt examples to reveal hidden assumptions, as well as step-by-step instructions for disabling memory features within each platform's settings. The article emphasizes that while deleting the entire account may not be enough, users can individually remove memory entries or turn off the feature altogether to better control their data.
The article provides practical guidance on managing memory features in major AI chatbots, relevant to privacy and data handling in AI interactions, but not a major industry shift.

Chatbots remember personal details — control their memory
The article reports that major chatbots — ChatGPT, Gemini and Claude — use memory functions to store personal details users share and reuse them to personalize future responses. Simple prompts can often make these saved items visible, including explicitly shared and implicitly inferred information (location, profession, family, estimated age, usage habits) and technical signals (browser, operating system, device). It shows each service’s controls for viewing, editing, disabling or deleting memories: ChatGPT (Settings → Personalization → Memories), Gemini (Settings → Personal context and activity history), and Claude (Settings → Features → Your memory files). The piece demonstrates models can reconstruct sensitive context from prompts, warns of privacy risks, and notes that deleting an account may not permanently remove memories unless stored entries are deleted first.
ChatGPT's memory knows more about you than you think
OpenAI's ChatGPT has significantly enhanced its memory feature, automatically storing and organizing user information such as interests, preferences, and long-term goals without explicit commands. The 'Dream' function, introduced in June, helps process and contextualize memories, allowing the chatbot to understand temporal context like past events. However, this automatic memory can lead to incorrect assumptions, such as misclassifying users based on temporary searches, raising privacy concerns. Users can manage their memory via the 'Personalisierung' (Personalization) tab, where they can enable/disable the feature, view and edit the AI-created profile, or delete all memories, while past conversations remain intact. Temporary chats offer a privacy-safe mode that does not save any information. This guide provides step-by-step instructions for managing ChatGPT's memory effectively, balancing convenience and privacy.
Google's Gemini Imports ChatGPT Memory
Google has added a new Import Memory feature to Gemini that lets users transfer personal preferences and conversation history from competing chatbots (e.g., ChatGPT, Claude) into Gemini. The tool provides a prepared prompt users copy into the other chatbot to produce a machine-readable export of saved preferences; the resulting output is pasted into Gemini and saved via an "Add Memory" action. Gemini also supports bulk conversation imports as ZIP files up to 5 GB and organizes imported chats for continued use. The feature is rolling out in some regions (not yet Germany at the time of reporting). Anthropic has introduced a similar capability for Claude, and Android Police reported on the immediate availability in select areas.
