WHY MADU

Your workflow stays yours.Only the context crosses.

Your repository

No third-party sync server. You choose the private GitHub repository and can revoke its token at any time.

Every crossing is manual

Nothing uploads in the background. You initiate every download, selection, and upload.

Context keeps growing

User messages, assistant replies, and historical plans travel with the conversation so you can continue on another computer.

THE NAME OF THE CROSSING

Why “Madu”?

I imagine every Codex conversation as a small boat carrying a train of thought.

码

CODE · CONTEXT

“Ma” points to code—and the context we build with AI.

渡

CROSSING · CONTINUE

“Du” means crossing: carrying unfinished ideas safely from one computer to another, so the work can continue.

Madu does not own your data or choose the course. It does one thing: carries your working memory safely to the other shore.

THE SAFE PROTOCOL

Download first.
Then upload.

This is enforced by the product, not left as a reminder.

PULL

Download remote

Read the encrypted remote conversations and record the current Git commit.

SELECT

Select local conversations

Only the conversations you select are encrypted and uploaded.

VERIFY & PUSH

Verify and upload

If the remote changed after your download, Madu blocks the upload and asks you to download again.

DESKTOP APP

See the whole crossing.

The guide, repository setup, language controls, and sync workspace live in one focused desktop client. Imported conversations can open directly in the running Codex app—no restart required.

Madu desktop client getting-started guide — A complete first-run guide, built into the client.

Madu settings and language selector — Connect a private repository and choose your interface language.

Madu GitHub sync workspace — Pull, select, and upload from one focused workspace.

SECURITY BY DEFAULT

GitHub only sees ciphertext.

Conversations are encrypted with AES-256-GCM before leaving your computer. The sync password is never saved, while the token is protected by your operating system.

Windows: DPAPI
macOS: Keychain
Token scope: Contents only
Upload mode: Manual

START CROSSING

Start from this computer.

Current version v0.4.5. The Windows installer is ready. The source supports macOS; a public DMG still requires signing and notarization on a Mac.
