Your engineering knowledge.
In Git. Forever.

A discipline worth keeping

Documenting experience for review and reflection is centuries old. A captain's log, kept as an operational record. Lewis and Clark's journals, turning an expedition into something the world could actually learn from. Edison's notebooks — thousands of pages, most of them failures, kept anyway, because a failure you can revisit is worth more than one you forget.

Modern engineering tools dropped that discipline somewhere along the way. The model survives; the reasoning behind it scatters into email, chat, and Slack threads no one will ever reopen. Cartenza brings the discipline back — one log entry at a time — creating the record that decisions and actions actually deserve.

Because knowledge is what you're trained on, whether that training is a classroom or a dataset. Wisdom is what you reflect on. Cartenza is where that reflection happens — for you, and for the agents working with you.

Where the logs actually live

Your logs are captured in Git. Forever. Notes, issues, observations, decisions and lessons learned are captured and organized in a tool engineers and developers already trust. Cartenza lets your agents assist in capturing that history — so you and the agents you work with can reflect on the logs you've built together.

Wisdom does not grow without experience. Your logs let you and your agents make better decisions.

• Works with Claude, ChatGPT, and any MCP-capable agent — no separate app to learn, no new interface to maintain
• Every entry is a Markdown file committed to your GitHub repo — fully auditable, diffable, portable
• Cancel anytime. Your knowledge stays in Git.

What you can achieve

Cartenza is your stage, where you lead your orchestra of agents. You can build on each agent's unique ability to help you ship, decide, and move your work forward. You're not alone, and your agents aren't isolated — you're on a stage together, delivering a performance that's captured in your logs.

Orchestrate you and your agents on the Cartenza stage, where you and your agents can reflect on your history, build on it, and lead your team to a better future.

How to get started

Four steps, and no credentials to copy anywhere.

1. Create your account at app.cartenza.ai/onboarding. Signing in is an emailed code — there's no password to invent and no key to keep safe.
2. Choose what your agent is for. Systems engineering, business, personal, or study and research. Your system prompt is written for you, with your agent's id already filled in, and emailed so you always have it to come back to.
3. Paste it into your assistant. Claude → Project → Project Instructions, or ChatGPT → Configure → Instructions. Add the Cartenza MCP servers in the same place — the prompt lists them.
4. Point it at a repo and start logging. Add your own GitHub repo, scope it to your agent, and authorize once with Connect via GitHub. Then just tell your assistant what you observed, decided or learned — it writes the entry to your repo and hands you a tappable link.
