Everything you need to manage your AI context

A native macOS workspace for the Markdown files your AI agents create. Edit, preview, organize, and bundle — all in one app.

Open any folder as a workspace

Point ContextLoom at any directory on your Mac. Your files stay where they are — local-first, no imports, no lock-in.

Three view modes: Edit, Split, Read

Write in a focused editor, preview side-by-side, or read rendered Markdown full-width. Switch modes instantly to match your workflow.

Live preview with Mermaid & syntax highlighting

Full GitHub Flavored Markdown rendering with Mermaid diagrams, syntax highlighting for 100+ languages, and clickable links — all in real time.

ContextDB taxonomy for LLMs

Organize files into a structured taxonomy that LLMs can traverse quickly. Specs, architecture, decisions, prompts — all in the right place.

Token-optimized Context Bundles

Select only the files you need and export them as a single context bundle. Less noise, fewer tokens, better answers from any AI tool.

Watch changes on disk in real time

Your AI writes a file and ContextLoom sees it instantly. No refresh needed — your workspace stays in sync as agents work.

iCloud Sync across Macs

Optionally sync workspaces across your Macs with iCloud Drive. Your data stays in your iCloud account — we never see it.

Open from the terminal with ctxtl

Use the ctxtl CLI tool to open files and workspaces in ContextLoom directly from your terminal. Fits right into your dev workflow.

Automate with contextloom:// URLs

Trigger ContextLoom actions from scripts, documentation, or other apps using the contextloom:// URL scheme.

Built for how you actually work

ContextLoom fits into your existing workflow. No new protocols, no cloud, no lock-in.

Built for AI workflows

The missing piece between your AI agents and your project knowledge. Write docs, organize context, and bundle exactly what your AI needs — all in one native app.

Native macOS performance

Built with SwiftUI and AppKit. Universal binary for Apple Silicon and Intel. Fast, lightweight, and feels right at home on your Mac — no Electron.

Plain files, full control

Just Markdown files on disk. Fully Git-compatible. No proprietary formats, no database, no lock-in. Your files are yours.
