Automatic and explicit
It saves the details you ask it to remember and picks up useful context on its own, then carries both into future chats without you re-stating them.
ChatGPT's memory is good inside ChatGPT and stops at its edge: Atlaso is the memory that follows you into Codex, Cursor, Claude Code and every other tool you connect.
Built-in memory is a real feature, and it works. We are not here to argue otherwise: an honest comparison starts by saying what a product does well before it says where that stops.
It saves the details you ask it to remember and picks up useful context on its own, then carries both into future chats without you re-stating them.
When enabled, it draws on your chats, uploaded files, and connected apps to personalize answers, so inside ChatGPT you repeat yourself less.
Saved memories live in Settings › Personalization › Memory, where you can review them and delete them one at a time or all at once.
These are not criticisms so much as the shape of a built-in feature: it is designed to make one product better, and it does. Each point below is from OpenAI's own documentation.
…will not include everything that ChatGPT remembers.
OpenAI's own docs say ChatGPT web uses ChatGPT memory, while local Codex clients use a separate local memory store, kept on your machine, off by default. The Atlas browser keeps a third store that OpenAI says is separate and controlled independently.
There's no memory API for developers. When users asked OpenAI to unify memory between ChatGPT and Codex, support logged it as feedback and the thread was closed without a native solution.
In the new system you review memory through a summary page that, in OpenAI's own words, “will not include everything that ChatGPT remembers”, so what you can audit is not the whole of what it holds.
“Don't mention this again” suppresses a detail but doesn't delete it; fully removing something means deleting every chat, file, and source it appears in. OpenAI may keep a log of deleted memories for up to 30 days.
On training: unless you turn off “Improve the model for everyone” in Data Controls, OpenAI says it may use your content, including past chats and saved memories, to train its models.
Five dimensions that decide what a memory feature is worth once you use more than one AI tool.
| Dimension | ChatGPT memory | Atlaso |
|---|---|---|
| Scope | One product. ChatGPT web, Desktop and Mobile share it; Codex CLI and the Atlas browser each keep a separate store. | Every connected tool. Claude Code, Codex, Cursor, Claude Desktop and more draw on one memory. |
| Visibility | A memory summary that OpenAI says won't include everything ChatGPT remembers. | See and search every memory Atlaso holds, in one dashboard. |
| Control | Suppress a detail with “Don't mention this again”; fully removing it means deleting every source it appears in. | Delete any memory on its own, and export everything as JSON. |
| Portability | No developer memory API; your ChatGPT memory doesn't follow you into other tools. | One memory across six AI tools, captured and recalled automatically, with personal and per-project scopes. |
| Training | Unless you turn off “Improve the model for everyone” in Data Controls, OpenAI says it may use your content, including saved memories, to train its models. | Never used to train models. Secrets are scrubbed on your device before anything is stored. |
Atlaso doesn't ask you to turn ChatGPT's memory off. They do different jobs and run side by side: ChatGPT's memory keeps making your ChatGPT conversations better, and Atlaso gives Codex, Claude Code, Cursor and your other tools one shared memory that ChatGPT's memory was never meant to reach.
Competitor details as of July 2026, from official OpenAI documentation.
No. ChatGPT's memory lives inside the ChatGPT product: web, Desktop and Mobile share it, while Codex CLI and the Atlas browser each keep separate stores. It never reaches Cursor or Claude Code. Atlaso is built for exactly that gap: one shared memory across every AI tool you connect.
