Description from the maker (original English)
Private, encrypted memory about you, shared by all your AI agents. Self-hosted; runs on a Pi.
These three are never merged into one score: opinions, measurements and popularity are different things.

Compared with every active server in this category in the registry. Stars count only when the publisher owns the repo.
It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
The registry does not list a required key, though some servers ask you to sign in on first use.
It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Both are good at what they do. They take the same basic approach as Recall: short third-person facts, a compact profile in context, search on demand. Recall uses that approach but changes who owns the memory and where it works.
Where Recall is better
| ChatGPT / Claude memory | Recall | |
|---|---|---|
| Which agents can use it | Only that vendor's apps. ChatGPT's memory doesn't reach Claude, Cursor or your scripts, and vice versa. | Every MCP client: Claude Code, Claude Desktop, Cursor, Codex, Gemini CLI, Zed, your own agents. Switch tools and keep your context. |
| Who holds the data | The vendor's servers, under their retention and policy terms. | Your disk, encrypted with your key (SQLCipher, AES-256). No account, and no network access at runtime. |
| Seeing what it knows | Saved memories are listable. Chat-history recall and synthesized summaries are paraphrased, and you can't fully inspect them. | Every fact is a plain line with an id and a date. recall list shows all of it, and recall audit shows which agent wrote what and when. |
| When changes apply | Claude's automatic summary refreshes on a 24-hour cycle. | Immediately, for every agent. |
| Dates | Every memory carries when it was learned, including backfilled ones, so agents can tell old facts from current ones. | |
| Mistakes and abuse | Writes containing secrets or ID numbers are rejected. Forget and replace are reversible for 30 days. HTTP tokens can be read-only. | |
| Context cost | A profile of about 1,500 tokens plus targeted search. Up to 5,000 facts without filling every prompt. | |
| Lock-in | Export is possible, but import depends on each vendor. | recall export --json, MIT licence, one 10 MB binary. |
Search quality is comparable. Hosted products don't publish their retrieval stack, so they can't be benchmarked directly. On our fact-retrieval benchmark, Recall's hybrid search (Recall@5 of 0.82) matches transformer embedding models such as bge-small (0.82) and MiniLM (0.85). It runs in about 150 µs with a 7.5 MB model and no ML runtime.
Where hosted memory still wins
remember.In short: if you use one assistant, on your phone, and don't mind the vendor holding your memory, use theirs. If you use several agents, want the data on your own hardware, and want to see and control every fact, use Recall. You can also use both: run recall import on facts exported from ChatGPT or Claude.

Claude Desktop, one click: download recall.mcpb and open it. The bundle covers macOS, Windows and Linux. It creates your encrypted store on first launch, and you can optionally enter a shared Tailscale server.
MCP Registry: Recall is listed as io.github.j4ckxyz/recall, so clients that browse the official registry can install it directly.
The installer:
SHA256SUMS. It stops if the checksum doesn't match.~/.local/bin (%LOCALAPPDATA%\Programs\recall on Windows).~/.recall/.recall doctor, a self-test of the model, search, the encrypted store and a real MCP handshake.Every release is installed and smoke-tested by CI before it's published, on macOS, Windows and Ubuntu (x64 and arm64), and in Debian 11 and 12, Fedora, Arch and Alpine containers. CI then re-runs the exact one-liners above against the published release. Linux binaries are static (musl), so they run on any distro, including 64-bit Raspberry Pi OS.
Prefer to read the script before running it? See install.sh and install.ps1. You can also build from source: cargo install --git https://github.com/j4ckxyz/recall --features vendored-openssl (drop the feature on macOS).
Back up `~/.recall/key`. Without it your memory cannot be decrypted. To keep the key in a password manager instead, set RECALL_KEY_CMD, for example RECALL_KEY_CMD='op read op://Private/recall/key'.
Copy this into Claude Code, Codex, Cursor or any agent that can run commands:
Install Recall for me (https://github.com/j4ckxyz/recall). It's a self-hosted
MCP server that gives all my AI agents a shared, encrypted memory about me.
recall doctor and confirm it ends with "All checks passed". If anything fails, show me the failing line and stop.
recall connect adds Recall to every agent it detects, and keeps a .before-recall backup of any config file it edits. You can also name agents: recall connect cursor vscode. recall disconnect undoes it.
To configure an agent by hand, every client runs the same command: recall mcp.
{ "mcpServers": { "recall": { "command": "/full/path/to/recall", "args": ["mcp"] } } }
claude mcp add --scope user recall -- recall mcp~/.codex/config.toml: [mcp_servers.recall], then command = "recall" and args = ["mcp"]Recommended: run one Recall server on an always-on machine (a Raspberry Pi, home server or desktop), and point every other device at it over your Tailscale tailnet. All your agents, on every device, then share a single memory, and none of it is reachable from the public internet.
laptop agents ─┐ ┌─ Raspberry Pi
desktop agents ─┼── recall mcp ── tailnet (WireGuard) ──► recall serve --tailscale work agents ─┘ (relays stdio) └─ encrypted store
1. On the server (after installing Recall and Tailscale):
recall token add laptop # one token per device; --read-only for read-only devices
recall serve --tailscale # listens on this machine's tailnet IP only, port 7878
To keep it running at boot on Linux:
mkdir -p ~/.config/systemd/user
cat > ~/.config/systemd/user/recall.service <<'UNIT' [Unit] Description=Recall memory server After=network-online.target tailscaled.service
[Service] ExecStart=%h/.local/bin/recall serve --tailscale Restart=always RestartSec=5
[Install] WantedBy=default.target UNIT systemctl --user enable --now recall sudo loginctl enable-linger "$USER" # start at boot without logging in
2. On every other device:
recall remote http://<server-name>:7878/mcp rcl_… # MagicDNS name, e.g. http://pi:7878/mcp
recall connect
The agents on that device still run recall mcp; it now relays to the server. recall doctor checks the connection, and recall remote off switches back to a local store.
Why this is safe
recall token revoke laptop.--tailscale binds only the tailnet interface, never your LAN or the internet. Don't use Tailscale Funnel for Recall.recall audit shows which device wrote each memory. "grants": [{ "src": ["you@example.com"], "dst": ["tag:recall"], "ip": ["tcp:7878"] }]
Clients that only accept a URL can use the server directly, with { "url": "http:// :7878/mcp", "headers": { "Authorization": "Bearer rcl_…" } }. Web and mobile apps such as claude.ai and ChatGPT can't reach a private tailnet yet.
recall serve also hosts a small web app, like Obsidian's graph view for what your agents know about you.
recall password # on the machine running Recall: generates a strong password (shown once)
recall serve # then open http://localhost:7878 (or your tailnet address)
On a tailnet you don't need the password. When recall serve runs on a machine that's on Tailscale, it signs you in automatically. It asks the local Tailscale daemon who owns the device you're connecting from: the same verified identity tsidp is built on, with nothing extra to deploy.
recall tailnet allow friend@example.com. Tagged devices (servers, CI) are never signed in this way.recall serve --tailscale), and also behind tailscale serve, where Recall trusts the Tailscale-User-Login header only if tailscale serve is actually proxying to Recall's port.Only the beginning is shown; read the rest in the repo
