Causolith

Make decisions. Keep the reasons.

Your code remembers what changed. Causolith remembers why. A native Mac workspace for the decisions, standards, evidence, and work behind your next great app.

Great apps have a why. Keep work, decisions, and reasons together.

Coming soon to the Mac App Store. Built for solo developers and small teams working with coding agents, Causolith keeps the reasoning close to the work — long after the original conversation has ended.

What it does

Make decisions that last

Capture the choice, the alternatives, and the reason. Find the thinking behind a feature when it is time to change it.

Keep the final say

Agents can search, gather evidence, and propose changes. You decide which proposals become accepted decisions and active standards in the native Judgment view.

Give your agents context

Connect compatible MCP clients, including Codex and Claude, to shared project memory. Check proposed work against your standards before implementation begins.

Keep the proof close

Attach screenshots, documents, and references. Compare visual evidence and add annotations while preserving the originals.

See the whole project

Explore the product map and follow the links between work, decisions, evidence, and history.

Take your memory with you

New projects keep portable .canon files in a folder you choose. Git is optional. Work in a native Mac app with search, keyboard shortcuts, and light and dark appearances.
