MEZ Pipeline · for Mac

Your agents write the code. Up to four reviewers read it.

Four independent seats — Mnemo, Echo, Zen and Obsidian — read what changed. None of them wrote it.

The panel

Four seats. One question each.

The author never grades itself.

  • MnemoMemory Does this undo or contradict something we already decided?
  • EchoThe ask Does it do what was actually asked?
  • ZenThe code Is it correct?
  • ObsidianOutside the frame The defect nobody was looking for.

Every review, one of four

“Nobody looked” is not “nothing’s wrong.”

  • Never openedNobody has looked yet — never painted green.
  • Partially reviewedIt names the seat that missed part of it.
  • Complete and cleanThe whole change was read. Nothing raised.
  • Complete with findingsEvery finding, signed by its seat.

Kai

A voice for what they found.

The headline, the whole finding, or nothing at all. Silent is the default.

More about Kai

Pick a voice and a personality, and ask Kai how a project is doing.

Kai runs on this Mac. No project leaves it unless you switch a provider on for that project yourself.

Coming — a name you choose. Kai is only the default.

Works with

Every agent you already run.

It sits beside your coding agent. Verified connectors for seven today:

  • Claude Code
  • Codex
  • Cursor
  • Gemini CLI
  • Qwen Code
  • Grok Build
  • Kiro CLI
And the rest

More are catalogued — VS Code-family editors, JetBrains IDEs, Xcode, Zed, OpenCode and others. Their connectors are not built yet, and the app says so instead of guessing.

Being built

Next, and marked as next.

Coming

The Vault

Everything the panel ever found, as plain linked notes you can browse. It is not in this version.

Coming

iPhone

The verdicts and Kai’s voice, in your pocket. Designed now; it gets a date when it is ready.

Zero-knowledge cloud

We can’t read a word.

  • Every review is kept on your Mac
  • The code goes only to the model you choose — or nowhere, with a local one
  • Sealed before it leaves · stored as ciphertext
  • No cookies, no trackers on this page
How the cloud is built

Today every review is kept on your Mac. When findings sync arrives, it rides the same zero-knowledge cloud as Control Tower: sealed on your Mac with AES-256-GCM before it leaves, kept on our servers as ciphertext — and a test on every build fails if the server ever gains a way to decrypt it.

The fine print

Prices are per person. Annual is twelve months for the price of ten: $170 or $530 per person per year.

Pro's 14-day trial starts when checkout opens — until then, request access. Studio has no trial.

Checkout is not open yet, so nothing is charged. The seats and project counts above begin when it opens.
