Your AI forgets
You Differ

Capture every conversation with Claude Code. The intent, the reasoning, the principles behind your decisions — stored automatically, searchable instantly.

Differ

Git is history
Differ is context

A lightweight Mac app that watches your Claude Code sessions — preserving not just what you built, but the reasoning behind it. The tradeoffs you weighed. The principles you followed.

Install and forget

Install and forget

Differ runs in the background, watching your Claude Code sessions and project files. No workflows to learn. No habits to build. You choose which projects — and everything stays local.

Differ Command

Ask anything

Search in Differ, ask Claude, or let Differ's subagent surface exactly what you need, when you need it.

Intent, preserved

Every conversation is stored, indexed, and linked to your codebase. Decisions don't disappear when the chat window closes.

Your codebase has a source of truth. Now your decisions do too.

Never re-solve the same problem

Your past conversations become a searchable knowledge base. Stop repeating yourself to your AI.

Onboard in minutes

Returning to a project or adding an engineer? The full decision history is right there.

Stay in flow

No copying prompts to docs. No bookmarking conversations. No "I should really organize this later." It just happens.

Differ is the first product from Sky Valley. We're building toward a future where software stays as adaptive after deployment as it was during creation. Where intent flows from prompt → code → runtime.

That future needs a new kind of system of record. Not version control for static code, but a living history of decisions and intent.

Differ is the foundation.
