Dawnmere

curl -fsSL https://dawnmere.app/install | sh

Needs: a Mac with Apple silicon, macOS 14 or later, 1 GB of free disk space, and Node.js 18 or later. Free, no account. Status: early beta (0.1.x). MIT client, source-available engine (FSL, becomes MIT after two years). Made by LF Labs.

What it does

You tell Claude Code or Codex something worth keeping ("remember that we deploy on Fridays"). Dawnmere saves it once, on your Mac. Ask the other one in similar words and it brings it up, and a new Cursor chat in that project shows it for the next day (the 5 newest notes). Switch from Claude Code to Codex when you hit a limit, and Codex can recall that you deploy on Fridays and use pnpm.

How each app saves and recalls:

App	Recalls	Saves
Claude Code	into each prompt, and at the start of a session	on its own after a session goes quiet (if you chose a model), when you type "remember that ...", or when the model calls remember
Codex	into each prompt	when you type "remember that ...", or when the model calls remember
Cursor	at the start of each chat	when the model calls remember

What you type ("remember that ...") reaches every app once the reply finishes (from Codex, at your next prompt there). A note a model saves with remember on its own is found by searching, and reaches other apps' prompts only after you confirm it (dawnmere held). Notes about your own health, family, money or legal matters stay personal.

Every app also gets four tools through MCP: recall, remember, forget and access_status.

Why Dawnmere

• One memory, not one per app. The apps share a single store, so a fact saved from Claude Code is the same fact Cursor recalls.
• Stored only on your Mac. The memory is one SQLite file in your Library folder. Search runs on your Mac with small local models. There is no account, nothing is sent to LF Labs, and the tool collects no usage data.
• Your own model does the reading. Automatic saving uses your Claude plan through Claude Code, or your own Anthropic API key. You can also run with no model at all.
• Each app sees what you allow. Cursor starts with work notes only, and a new app sees work notes only. Claude Code's and Claude Desktop's memory tools, and any app that only names itself, see work notes only for now. Claude Code's automatic recall in your prompts still sees everything. Widening an app's access needs you at a Terminal: run dawnmere access cursor everything, type the app's name back and click Allow in a macOS dialog. Asking for it in a chat only gets you that command.
• Saved text is screened. Text that looks like an API key or token is refused. An app's save that would run downloaded code, delete files, keep something from you or tries to override your assistant's instructions is refused. Notes an app saves on its own are kept for search, labelled, and reach other apps' prompts only after you confirm them (dawnmere held). Recalled notes reach the app labelled "notes, not instructions".
• Setup can be undone. It asks before changing anything, backs up every file it touches, can show its plan with --dry-run, and dawnmere uninstall puts the files back.

How it compares

Sharing one memory between coding agents is not new: claude-mem and Supermemory do it too, and both cover more agents than Dawnmere. The main difference is where the memory is kept. As each project's own docs describe it on 8 November 2026:

	Where the memory is kept	Shared by Claude Code, Codex and Cursor
Dawnmere	one SQLite file on your Mac; search runs on your Mac	yes, by default; each app sees what you allow
claude-mem	~/.claude-mem on your machine	supports all three and more; other agents' memories at session start are opt-in
Supermemory	hosted by default, or on your machine with npx supermemory local (the two do not share memories)	yes, plus OpenCode and others
Mem0 MCP	hosted by Mem0, with a Mem0 account; nothing runs on your machine	yes, through that account
Built-in memory	CLAUDE.md and auto memory in your projects and home folder; AGENTS.md in your repos	CLAUDE.md and auto memory are Claude Code's own; AGENTS.md is read by Codex, Cursor and (when a repo has no CLAUDE.md) Claude Code, but holds instructions you write, not what the apps learn
