Four tools. One philosophy.
Local-first tools
for the way you
actually build.
Cortex is a family of native, local-first tools for developers — an AI agent, a code editor, a database client, and persistent memory for Claude Code. Your machine, your data, no token tax.
Cortex Agent
macOS · SwiftUI app

Memory that remembers what matters.

Learn moreBuilt on one idea: your machine first.
Every Cortex tool runs locally by default. No data leaves your machine unless you ask it to, nothing burns API tokens behind your back, and everything stays fast because there's no round trip to a server you don't control.
Local-first
Your data lives on your machine, period.
Zero token tax
Uses your local CLIs and models by default.
Native & fast
Real apps, not Electron wrappers.
One language
