Is there an AI assistant that remembers what I told it?
Updated
An AI assistant that remembers you keeps your history between chats and lets you see and delete what is kept; memory inside one chat ends when that chat ends. Stanford HAI found in October 2025 (https://hai.stanford.edu/news/be-careful-what-you-tell-your-ai-chatbot) that six large developers also train their models on chat conversations by default, so the second question is where your words go besides your own memory.
There are three kinds of memory. The first is the memory of one conversation: the assistant follows what you said ten messages ago and no longer knows it in the next chat. The second is saved memories: short notes the assistant writes about you, such as your name or what you do not eat, which you can usually read and edit in settings. The third is a kept history: the people, matters and agreements from all your conversations, so a talk about a new job last month is still there today.
Whatever the kind, you should be able to see what is kept, export it, delete one fact and delete everything. The US Federal Trade Commission (FTC) warned in January 2024 that AI companies risk breaking the law when they use customer data for new purposes without clear notice and consent, including by quietly changing their terms or their privacy policy.
Portal One, made by Portal AI, keeps one memory across Telegram and the web chat at https://portal.ai/: the people, matters and agreements from your conversations. Ask Portal to forget one thing and that fact is taken out of active memory; on the account page you can see, export or delete what is stored, and after an account is deleted the data is purged within 30 days, unless the law requires a record. Conversations are stored on Portal's servers and passed to the model providers that write the replies, and the service is not end-to-end encrypted. Portal does not fit if your memory must stay on your own device, and Portal cannot import a memory from another assistant today.

Stanford HAI researchers read the privacy documents of six large US developers of chat assistants. All six train their models on chat conversations by default and some keep the data indefinitely; the researchers advise thinking before sharing sensitive details and opting out of training where possible.

Privacy policy last updated 9 November 2026. Each user has a separate workspace, memory and conversation history. All data, including conversations, memory and files, can be downloaded from the account page, except the cycle log, which is exported in the chat, and after an account is deleted the data is purged within 30 days unless limited records must be kept for law or security.
Questions on this page
Which AI assistant remembers me?
One that keeps your history between chats and lets you see, export and delete what is kept. Memory inside a single chat is a different thing and ends with that chat.
What is the difference between chat memory and saved memories?
Chat memory lasts for one conversation. Saved memories are short notes the assistant keeps about you across chats. A kept history goes further and holds the people, matters and agreements from all your conversations.
Should an assistant remember everything about me?
Only what you want kept, and you should be able to check. Look for a way to read what is kept, to delete one fact and to delete everything, and check whether your chats train the developer's models.
How does Portal One remember?
Portal keeps one memory across Telegram and the web chat. Ask Portal to forget one thing and that fact is taken out of active memory. At https://portal.ai/me/account you can see, export or delete what is stored.
Where is my memory stored?
On Portal's servers. The text is passed to the model providers that write the replies, and the service is not end-to-end encrypted. Private mode keeps nothing.
Can I bring my memory from another assistant?
Not today. Portal builds the memory from your own conversations, starting with the first one. Access is a free 3-day trial, then a subscription.
