Does Claude have memory?

Yes. Since 25 August 2026 Claude keeps one memory across chat and Cowork, adds to it while you talk, and lists it topic by topic so you can edit or delete any line. Here is what it remembers, where the switches are, what happens inside Projects — and the material it still never sees.

Yes — and since 25 August 2026, more of it than most write-ups describe. Anthropic's announcement that day opens: "Starting today, the memory you use in chat is the same as in Claude Cowork." Memory is "on by default on Free, Pro and Max plans across web, desktop, and mobile"; on Team and Enterprise, "admins control availability for their organization, and memory is off for individual users until they turn it on." Claude now adds to memory while you talk rather than after a chat ends, and everything it keeps is listed topic by topic where you can read, edit or delete it.

Below is the accurate version, read on Anthropic's blog and help center on 2026-09-08, in the order you'll actually need it: what Claude remembers and where, how to see and delete a single topic, the sensitive-topics switch, the on / pause / reset controls, what each plan gets, and the question that fills the forums — whether a new chat in a Project knows the old ones. Then the boundary that matters if your week runs on client work.

What Claude remembers now, and where

Anthropic describes the source plainly: Claude "can generate memory based on your chats." The mechanism changed in August. Claude now "saves memory as a set of individual topics as you chat, rather than summarizing conversations after they end. Mention that a deadline moved, and your next conversation already knows." It saves on its own, and you can also say "remember this" to store something directly.

What it keeps, among the items on Anthropic's list: "your role, projects, and professional context," "the people and places in your work and life," "communication preferences and working style," and "project details and ongoing work." In practice: who you are, how you like answers built, the clients and initiatives you keep raising, and the decisions you've already worked through with it.

Where that memory lives is the part people trip on, because there are three places and they don't all share:

One more thing sits beside memory and is easy to confuse with it: chat search. Memory is what Claude distilled; search is Claude going back to reread a specific old conversation when you ask ("What did we discuss about the pricing revision?"). Search is "available to users on paid plans (Pro, Max, Team, and Enterprise plans)," is switched on by default once it reaches your account, and when Claude uses it "you'll see citations linking back to the original chats." Memory works without it; search is the tool for the exact quote from June.

How to see the topic list, and delete one topic

This is where Claude is genuinely strong, and it's worth five minutes of your time. Anthropic: "See exactly what Claude remembers about you in Settings > Memory. Everything Claude remembers is listed under Topics. Select any topic to read it, then use the edit icon to change it or select 'Delete' to remove it. Fix something in one topic and the change applies to every conversation from then on."

• See it. Open Settings → Memory and read the list under Topics. You are reading the actual record, not a paraphrase of it.
• Correct it. Select a topic and use the edit icon — the blog's example is fixing your company's old name once so "every conversation from then on gets it right." You can also just tell Claude in a chat what to remember, change or forget; Anthropic says "the update applies to your next conversation."
• Delete one thing. Select the topic, choose Delete. Precise, and it leaves everything else intact — reach for this before anything wider.

The detail that catches people: deleting a chat does not delete the memory made from it. Anthropic's retention section is explicit — "when a conversation expires or is deleted, related memory entries generated from it won't be removed, but you can delete individual memories at any time." If the goal is to make Claude forget something, the Topics list is the lever, not the chat history.

The sensitive-topics switch

Off by default, and worth knowing about either way. Anthropic: "By default, Claude does not store topics related to personal or sensitive subject matter, like your health, race, ethnicity, religious beliefs, politics, gender identity, and other similar areas." If you'd rather not keep re-explaining those, turn on Include sensitive topics in memory under Settings → Memory — or from the one-time notice Claude shows the first time it declines to save something for this reason.

Three consequences Anthropic spells out once the switch is on. It works forward only: "anything from before you turned it on isn't saved retroactively." You'll see a notice each time Claude saves something in one of these areas. And if you later turn it off, "Claude removes any sensitive items already saved to memory." Some things are never saved regardless — Anthropic lists "government ID numbers, criminal history, financial account numbers, and immigration status." On iPhone, the notice only appears on the latest version of the app; on an older version Claude simply won't save the sensitive item.

For client work the default cuts the way you'd want: a client's health situation mentioned in passing on a call you debriefed with Claude stays out of the record unless you decide otherwise.

How to turn memory on, pause it, or reset it

• On. Anthropic: toggle memory on "by navigating to Settings > Memory and turning on Generate memory from chats." On Free, Pro and Max it is already on by default; on Team and Enterprise it appears once an owner has enabled it for the organization.
• Pause. Switch the same toggle off and choose Pause memory: Claude "keeps its existing memory, including sensitive topics if you have it turned on, but won't use memory or make new memories." Chats held while paused "won't be added to memory if you turn it back on." The right move for a clean stretch of work you don't want colouring later answers.
• Reset. Choose Reset memory: it "permanently deletes all memories including project memories," and "once you select this option and click 'Reset memory,' this cannot be undone." Use it deliberately, not as a tidy-up — deleting one topic is almost always what you meant.
• One conversation only. Start an incognito chat (the ghost icon on a new chat outside a Project). Anthropic: "Claude won't remember your chats, so they won't be saved to Claude's memory or your chat history," and it "won't pull information from incognito chats when searching previous conversations."
• Stop the searching, keep the memory. Chat search has its own toggle on the same screen — switch off "Search and reference chats." The two features are independent.

What each plan gets, in Anthropic's words

If your settings show Memory under Capabilities rather than on its own Memory page, you are on what Anthropic calls the legacy experience — "a small number of Team and Enterprise organizations" still are — and the legacy section at the foot of Anthropic's memory article is the one that applies to you.

Every Anthropic quotation on this page comes from five pages read on 2026-09-08: the claude.com post "Claude's memory works everywhere, and you decide what's in it" (25 August 2026); the help-center articles "Use Claude's chat search and memory to build on previous context," "Import and export your memory from Claude," and "How can I create and manage projects?" (each shown as updated within the week); and "Use Google Workspace connectors" (shown as updated over three weeks ago). Apple's wording in the FAQ is from Apple Newsroom, 8 June 2026. Where a page states no default or no limit, neither do we. Rollouts reach accounts at different times; your own settings screen is the authority.

Does Claude remember other chats in a project?

This is the question behind most of the searches that land here, and the complaint that runs through r/ClaudeAI threads is, in effect: what's the point of projects if new chats don't know the old ones? The honest answer is that three different things are in play, and Anthropic documents each one.

• Project knowledge. The files, text and instructions you add to the project. Anthropic: "Anything you upload to this space will be used across all of your chats within that project." And, in the same article, the sentence that explains the frustration: "Context is not shared across chats within a project unless the information is added into the project knowledge base."
• Project memory. Distilled, not verbatim. "Each project has its own separate memory space and dedicated project summary." What Claude learned about the engagement in earlier project chats is carried into new ones — as memory, not as the transcript.
• Chat search. On paid plans, ask and Claude goes back to read: "Can you find our conversation about the pricing revision?" Searches inside a project are "limited to within each specific project," and results come with citations back to the original chats.

Put together: a new chat in a Project does not reread the old ones. It starts from what the project's memory distilled and from whatever sits in project knowledge; for a specific detail, ask, and on a paid plan Claude searches that project's history for it. Across different Projects the answer is simply no — each space is "separate from other projects or non-project chats." In a passage Anthropic addresses to Team and Enterprise plans, it also notes that moving a chat into or out of a project controls which memory it feeds: remove a stray chat from a project and "it will be included in Claude's non-project memory instead."

A workable habit if you run one Project per engagement: keep a short running notes file in project knowledge — decisions, open items, the numbers that keep coming up — and update it after anything that matters. It's the same discipline every filing system asks for, and it carries the same cost: it only works while you keep doing it.

Moving memory in from ChatGPT

If you're arriving from ChatGPT, Claude will take your memory with you — as text: the Start import flow under Settings → Memory takes the export from your previous assistant and stores it "as individual memory entries," with Anthropic's own caveats that the import is "experimental" and that Claude "may not retain imported personal details unrelated to work." What travels is the memory the old assistant had derived from your chats — not the chats themselves, and not anything that never entered them. The step-by-step, for Claude and Gemini, is in how to move your ChatGPT memory to Claude.

Where Claude's memory stops

Everything above is real, and if you pay for Claude Pro you should use all of it. But notice what every part has in common: Claude's memory is built from your conversations with Claude. Anthropic's description is memory generated "based on your chats," and its list of what Claude remembers is a list of things about you and your work — never a list of documents.

If your week runs on client relationships, the boundary shows up fast. However carefully you've set the toggles, Claude's memory does not hold:

• The reply that landed at 3:42 PM yesterday on a thread you were CC'd into, ahead of tomorrow's 9 AM call.
• The revised statement of work a client's counsel sent back on Tuesday, three replies deep in a thread you filed but didn't reread.
• What the board chair actually asked about the timeline in last month's review — that's in a transcript, not a chat.
• The voice memo you recorded walking to the car, or the screenshot you took of a slide.

None of it passed through a chat window, so no amount of chat memory reaches it. You can paste things in — and if you've ever pasted a long thread into Claude to get one answer, you know the tax: it's per-question work, and the original stays wherever it was.

One caveat, stated plainly because it cuts close: Claude can fetch from a connected Google account. Anthropic's Gmail, Google Calendar and Google Drive connectors are "available for all users on Claude and Claude Desktop," and the same page says "Claude only accesses your data when you explicitly ask a question or request an action requiring this information, and retrieves the minimum information needed." That is retrieval at the moment you ask, from the whole account you connected — a different mechanism from memory, and a different bargain from handing over the one thread you meant to. Anthropic's description of the memory record itself stays what the sections above say: generated "based on your chats." (Help center, read 2026-09-08.)

None of that is a flaw in Claude. It's the shape of the product: a chat assistant remembers the conversation. Holding the material your work actually runs on is a different job.

A different answer: an assistant that remembers what you send it

Equerry is a personal assistant built around that second job. Rather than remembering what you typed into it, it remembers what you deliberately hand it — and hands it back with the original attached.

• CC or forward the threads that matter. Add your own Equerry address (something like mark@mail.getequerry.app) to a client thread and every reply that keeps it on the thread is remembered too. It reads the thread — not your inbox. No account connection, no full-mailbox handover.
• Add the rest the way you already capture. A PDF or screenshot through the share sheet, a voice memo after a call, a typed note. It all lands in one place and is searchable together.
• Ask later, and open the source. "What did the CFO say about pricing in October?" comes back with a source chip pointing at the exact email or note behind it. Tap it and you're reading the original, not a summary of a summary.
• Get briefed before the call. A morning brief can surface Thursday's late reply you hadn't opened, so you walk into Friday's meeting already current.
• See and delete what it kept. Settings → Your Memory lists every remembered fact, line by line, and each saved item shows what was taken from it. Remove any line and it's gone.

The point isn't that this replaces Claude. Keep Claude for the drafting and the thinking — it's good at both, and its memory now makes it better. But when the question is "what did the client actually say," the answer was never in a chat box. It was in an email, a document, or a note, and it needs somewhere that holds all three at once and can tell you where the answer came from. Equerry is available on the App Store.
