Claude Code for your notes, not just your repo

Plenty of people already point Claude Code at an Obsidian vault from the terminal. Cortext gives that workflow a home: a native macOS Markdown workspace where Claude Code is one of two agent runtimes, surrounded by an editor, document history, approvals, and long-term memory.

Why not just the terminal?

Claude Code in a terminal is powerful, but notes need things a repo doesn't: a real Markdown editor, a way to review what the agent changed in prose, and a knowledge structure that outlives each session. Git diffs of paragraphs are hard to read, and every session starts without what the last one learned.

What Cortext adds around Claude Code

  • Editor and agent side by side: write in a rich Markdown editor while Thoughts, the agent panel, works on the same files.
  • Document history for every edit, with diff and restore, independent of git.
  • An approval gate for risky Bash, unknown tools, and writes outside the workspace, plus a sandbox for shell commands.
  • Local memory: preferences and saved views carry across sessions, and the chat tells you when something was remembered.
  • An LLM-maintained wiki in .cortext/wiki/ that the agent can search alongside your notes.
  • @ file references and / skills. Skills are plain SKILL.md files the agent can write for you.

How the Claude Code runtime works

Cortext drives the Claude Code CLI installed on your Mac and uses its existing sign-in. Provider settings such as custom endpoints and model mappings are read from ~/.claude/settings.json through an allow-list.

Inside Cortext, the system prompt, tools, MCP servers, and permissions are managed by Cortext, so your global hooks and project-level Claude Code settings don't change how the agent behaves in your notes.

Or use another model

Prefer something else? Switch to the native Cortext runtime and connect Anthropic, OpenAI, Google, OpenRouter, DeepSeek, Moonshot, Z.AI, or any OpenAI-compatible endpoint with your own keys.
