# How to Delete ChatGPT Memory and Manage What It Keeps

How to delete ChatGPT memory depends on which system your account runs: the memory summary that became the default in June 2026, or the legacy saved memories list ([release notes](https://help.openai.com/en/articles/6825453-chatgpt-release-notes)). Both are managed from Settings > Personalization > Memory, item by item or wholesale ([Memory FAQ](https://help.openai.com/en/articles/8590148-memory-faq)). And if you arrived asking whether ChatGPT has memory at all: yes, it has since it reached Free, Plus, Team, and Enterprise accounts in September 2024 ([OpenAI](https://openai.com/index/memory-and-new-controls-for-chatgpt/)). What the system stores and why OpenAI redesigned it is covered in [How ChatGPT Memory Works](/blog/chatgpt-memory); this page is the deletion steps and off switches, checked against OpenAI's documentation as of September 2026.

## Delete individual ChatGPT memories

On the current system, corrections happen in the memory summary. Open it from Settings > Personalization > Memory, then type what you want changed into the text box at the bottom of the summary, or highlight any text to make a specific correction ([Memory FAQ](https://help.openai.com/en/articles/8590148-memory-faq)). Under a response, the book icon lists the memories that shaped it, and the three dot menu on any memory there lets you correct it ([Memory FAQ](https://help.openai.com/en/articles/8590148-memory-faq)).

On the legacy system, saved memories are discrete entries: delete them individually in settings, or ask in chat, since ChatGPT updates, combines, or removes saved memories when asked ([Memory FAQ](https://help.openai.com/en/articles/8590148-memory-faq)).

## Clear all ChatGPT memory at once

On the memory summary page, open the three dot menu and select "Delete and turn off memory" ([Memory FAQ](https://help.openai.com/en/articles/8590148-memory-faq)). Two caveats are documented. It does not delete your past chats, and if you re-enable memory later, ChatGPT may create new memories from chats still in your history, including older ones ([Memory FAQ](https://help.openai.com/en/articles/8590148-memory-faq)). The control is on the web, with mobile rolling out ([Memory FAQ](https://help.openai.com/en/articles/8590148-memory-faq)).

On the legacy system, clear all saved memories in settings; OpenAI may retain a log of deleted saved memories up to 30 days for safety and debugging ([Memory FAQ](https://help.openai.com/en/articles/8590148-memory-faq)). Retention windows like that one are compared across assistants in [AI data retention](/guides/ai-data-retention).

## What deleting a chat does and does not delete

Memory is stored separately from chat history, and the consequences run in both directions:

- Deleting a chat does not delete memories created from it ([Memory FAQ](https://help.openai.com/en/articles/8590148-memory-faq)).
- Deleting a memory does not remove mentions of it from past chats; you must delete the specific chat where it was shared ([Memory FAQ](https://help.openai.com/en/articles/8590148-memory-faq)).
- Fully deleting a fact means removing every source it appears in: past chats, archived chats, files, the memory summary, and any connected apps that contain it ([Memory FAQ](https://help.openai.com/en/articles/8590148-memory-faq)).

## The memory full notice

Memory full belongs to the legacy saved memories list, which has a fixed capacity OpenAI does not publish. Automatic memory management, added October 15, 2025, deprioritizes stale entries specifically to keep the list from reaching capacity ([release notes](https://help.openai.com/en/articles/6825453-chatgpt-release-notes)). Users report that once the list is full, new memories stop being saved until space is freed ([OpenAI community thread](https://community.openai.com/t/chatgpt-plus-plan-memory-issue-no-warning-when-memory-is-full-leading-to-lost-entries/1111613)). The fixes: delete entries you no longer need, clear the list, or switch to the current summary system, which updates itself and shipped with increased capacity for Plus and Pro ([release notes](https://help.openai.com/en/articles/6825453-chatgpt-release-notes)). Switch back and forth at Settings > Memory ([Memory FAQ](https://help.openai.com/en/articles/8590148-memory-faq)).

## Turn off ChatGPT memory entirely

- Current system: enable or disable memory at any time in Settings > Personalization > Memory ([Memory FAQ](https://help.openai.com/en/articles/8590148-memory-faq)). "Delete and turn off memory" (above) wipes and disables in one step ([Memory FAQ](https://help.openai.com/en/articles/8590148-memory-faq)).
- Legacy system: turn off "Enable memory" in Settings > Memory ([Memory FAQ](https://help.openai.com/en/articles/8590148-memory-faq)).
- On Free accounts in the EEA, Switzerland, Norway, Iceland, and Liechtenstein, the lightweight chat referencing is opt-in at Settings > Personalization > Memory > Reference chat history ([release notes](https://help.openai.com/en/articles/6825453-chatgpt-release-notes)).

## Temporary Chats remember nothing new

To start one, open a new chat and click the pill shaped "Temporary" button in the top right corner, and choose personalized or non-personalized before the conversation begins; the choice cannot be changed afterward ([Temporary Chat FAQ](https://help.openai.com/en/articles/8914046-temporary-chat-faq)). A non-personalized Temporary Chat uses no memory and no custom instructions, while a personalized one can reference existing memories but will not create or update any ([Temporary Chat FAQ](https://help.openai.com/en/articles/8914046-temporary-chat-faq)). Unsaved Temporary Chats stay out of your history, though OpenAI may keep a copy up to 30 days for safety ([Temporary Chat FAQ](https://help.openai.com/en/articles/8914046-temporary-chat-faq)).

## Business, Enterprise, and Healthcare workspaces

- Memories are tied to each account and cannot be shared with other members of a workspace ([Memory FAQ, Business version](https://help.openai.com/en/articles/9295112-memory-faq-business-version)).
- Individual members can disable memory in their own settings, and a workspace owner can turn it off workspace-wide, which deletes members' existing saved memories ([Memory FAQ, Business version](https://help.openai.com/en/articles/9295112-memory-faq-business-version)).
- Deleting a workspace permanently deletes its conversations and memories; deactivation after a lapsed subscription does not ([Memory FAQ, Business version](https://help.openai.com/en/articles/9295112-memory-faq-business-version)).
- In ChatGPT for Healthcare and Enterprise regulated workspaces, improved memory is off by default, and owners or admins choose which roles can use it ([Memory FAQ](https://help.openai.com/en/articles/8590148-memory-faq)).

## For builders: deletion you can implement

ChatGPT's controls delete data inside OpenAI's product; they do nothing for the assistant you are building. For your own memory layer, past.dev is a memory API: POST /api/v1/ingest accepts raw text with its original timestamp (fields: content, timestamp), and POST /api/v1/recall (field: query) returns ranked, dated evidence with sources and one of four status values (Supported, Conflicted, NoKnownSupport, UnknownBecauseDegraded). Facts carry event time, validity windows, and supersession links, with entity resolution across sources and deployment managed or self-hosted in your own Postgres. Start with the [Memory API quickstart](/docs/memory-api/quickstart) and the [benchmarks](/benchmarks).
