# How to give Claude Duet better memory

Claude Duet runs on your Claude account, so the memory, skills, and connectors you set up in Claude are there from your first message ([Claude support](https://support.claude.com/en/articles/17631495-get-started-with-claude-duet)). It searches your past chats for context, and the Search and reference chats setting controls that search ([Claude support](https://support.claude.com/en/articles/11817273-use-claude-s-chat-search-and-memory-to-build-on-previous-context)). KnowMan runs locally with `npx -y @knowman/mcp` or as a hosted server at https://api.knowman.io/mcp, using OAuth sign-in or an [API key](https://www.knowman.io/guides/mcp-server-knowledge-base).

## How Duet carries over your Claude memory

Claude Duet runs on your Claude account, so the memory, skills, and connectors you set up in Claude are available from your first message ([Claude support](https://support.claude.com/en/articles/17631495-get-started-with-claude-duet)). Anthropic describes the same carry-over: memory, skills, and connected apps come with you, so setting it up requires minimal work ([Claude](https://claude.com/resources/articles/claude-duet)).

Duet also uses and adds to your memory, so what Claude knows about you is there from your first message ([Claude support](https://support.claude.com/en/articles/11817273-use-claude-s-chat-search-and-memory-to-build-on-previous-context)). Memory is on by default for Free, Pro, Max, and Ultra plans on the web, Claude Desktop, and Claude Mobile ([Claude support](https://support.claude.com/en/articles/11817273-use-claude-s-chat-search-and-memory-to-build-on-previous-context)). Duet itself is a research preview for Pro, Max, and Ultra plans ([Claude support](https://support.claude.com/en/articles/11817273-use-claude-s-chat-search-and-memory-to-build-on-previous-context)).

If you start separate channels in Duet for different topics, they share the same memory ([Claude support](https://support.claude.com/en/articles/17631495-get-started-with-claude-duet)).

## How Duet searches past chats

Duet can search your past chats to pick up context from earlier work, so you do not have to repeat yourself ([Claude support](https://support.claude.com/en/articles/17631495-get-started-with-claude-duet)). It searches your Claude Duet chats and your chats in Claude outside of projects ([Claude support](https://support.claude.com/en/articles/17631495-get-started-with-claude-duet)).

Two boundaries apply. When you delete a chat, it is removed from Duet's search ([Claude support](https://support.claude.com/en/articles/17631495-get-started-with-claude-duet)). Claude also will not pull information from incognito chats when searching previous conversations ([Claude support](https://support.claude.com/en/articles/11817273-use-claude-s-chat-search-and-memory-to-build-on-previous-context)).

## The setting that controls chat search

Duet's chat search uses the same Search and reference chats setting as Claude ([Claude support](https://support.claude.com/en/articles/17631495-get-started-with-claude-duet)). The setting also controls whether Duet can search your past chats ([Claude support](https://support.claude.com/en/articles/11817273-use-claude-s-chat-search-and-memory-to-build-on-previous-context)).

To stop the search, go to Settings > Your Claude (or Settings > Memory in the older Settings layout) and switch the toggle next to Search and reference chats off ([Claude support](https://support.claude.com/en/articles/11817273-use-claude-s-chat-search-and-memory-to-build-on-previous-context)). The Duet guide documents the same path ([Claude support](https://support.claude.com/en/articles/17631495-get-started-with-claude-duet)).

## What stays in memory when you disconnect a connector

Disconnecting an app stops Duet from accessing it from that point on, but memory of past information from earlier conversations is kept ([Claude support](https://support.claude.com/en/articles/17631495-get-started-with-claude-duet)). You start every connection yourself, and you can disconnect any app at any time ([Claude support](https://support.claude.com/en/articles/17631495-get-started-with-claude-duet)).

Duet works with connectors you have connected in Claude, such as Gmail, Google Calendar, Google Drive, Slack, QuickBooks, HubSpot, Docusign, and Calendly ([Claude support](https://support.claude.com/en/articles/17631495-get-started-with-claude-duet)). To trim what those earlier conversations left behind, use the memory management steps below.

## Review and edit what Claude remembers

See and manage what Claude remembers in Settings > Your Claude by selecting Manage next to Your memory ([Claude support](https://support.claude.com/en/articles/11817273-use-claude-s-chat-search-and-memory-to-build-on-previous-context)). Claude saves memory on its own, and you can tell Claude to "remember this" to save something directly ([Claude support](https://support.claude.com/en/articles/11817273-use-claude-s-chat-search-and-memory-to-build-on-previous-context)).

You can also update memory from a chat. Tell Claude what to remember, change, or forget, and the update applies to your next conversation ([Claude support](https://support.claude.com/en/articles/11817273-use-claude-s-chat-search-and-memory-to-build-on-previous-context)). To let Claude remember sensitive personal topics, turn on Include sensitive topics in memory in Settings > Your Claude (or Settings > Memory in the older Settings layout) ([Claude support](https://support.claude.com/en/articles/11817273-use-claude-s-chat-search-and-memory-to-build-on-previous-context)).

## What Duet cannot see

Duet cannot see all of your projects or the files on your computer, and it can read your work in Claude but cannot change it ([Claude support](https://support.claude.com/en/articles/17631495-get-started-with-claude-duet)).

One related boundary on memory: it is shared between Chat and Claude Cowork when Cowork runs in the cloud, but Cowork sessions that run locally on your computer do not use memory ([Claude support](https://support.claude.com/en/articles/11817273-use-claude-s-chat-search-and-memory-to-build-on-previous-context)).

## Where KnowMan fits

KnowMan saves articles and links, reads and tags them, and keeps memories such as claims, decisions, and playbooks. Its MCP server runs locally with `npx -y @knowman/mcp` or as a hosted server at https://api.knowman.io/mcp, using OAuth sign-in or an API key. Set up the documented server connection in your [MCP client](https://www.knowman.io/guides/what-is-an-mcp-server).

KnowMan's documented client configs cover Claude Desktop, Claude Code, and Cursor. If you use those, start with [a Claude knowledge base](https://www.knowman.io/guides/claude-knowledge-base), [Claude Code setup](https://www.knowman.io/guides/claude-code-knowledge-base), or [an MCP server knowledge base](https://www.knowman.io/guides/mcp-server-knowledge-base). For the wider pattern, see [persistent memory for AI agents](https://www.knowman.io/guides/persistent-memory-for-ai-agents).

## Connect KnowMan to Claude

KnowMan runs as a hosted MCP server at https://api.knowman.io/mcp, with OAuth sign-in on a KnowMan consent page or an API key. For the steps in Claude, see [Claude Duet and your knowledge base](https://www.knowman.io/guides/claude-duet-knowledge-base).

## Questions

### Does Claude Duet use my Claude memory?

Yes. Duet runs on your Claude account, so the memory, skills, and connectors you set up in Claude are there from your first message ([Claude support](https://support.claude.com/en/articles/17631495-get-started-with-claude-duet)). Duet also uses and adds to that memory ([Claude support](https://support.claude.com/en/articles/11817273-use-claude-s-chat-search-and-memory-to-build-on-previous-context)).

### How do I stop Claude Duet from searching my past chats?

Duet's chat search uses that same setting ([Claude support](https://support.claude.com/en/articles/17631495-get-started-with-claude-duet)).

### Does disconnecting a connector erase what Duet remembers?

No. Disconnecting an app stops Duet from accessing it from that point on, but memory of past information from earlier conversations is kept ([Claude support](https://support.claude.com/en/articles/17631495-get-started-with-claude-duet)). You can disconnect any app at any time ([Claude support](https://support.claude.com/en/articles/17631495-get-started-with-claude-duet)).

### Can I connect KnowMan to Claude Duet?

KnowMan offers a local MCP server with `npx -y @knowman/mcp` and a hosted server at https://api.knowman.io/mcp, which uses OAuth sign-in or an API key. See the MCP server knowledge base guide for setup details.
