Ground Control Chat vs Ledge Notebook

Every Claude Code session on your Mac becomes a pixel pilot on your phone. Ground Control shows your AI coding agents as unique little creatures marching on a neon city street. Cyan means working. Lavender means idle. Pink means one of them needs you. Tap a pilot to open its conversation. Read every reply as it streams in. Send new orders from the couch, the train, or the other side of the world, and watch your actual terminal on the Mac update live. SETUP IN ONE MINUTE Run one command on your Mac (npx @clastres/groundcontrol), scan the QR code it prints, done. No account. No signup. PRIVATE BY ARCHITECTURE Your pairing key is generated on your Mac and shared only through the QR code you scan. Everything travels end to end encrypted. Our relay routes sealed bytes and cannot read them. We store nothing. UNIQUE PILOTS Every session hatches its own creature, generated from its identity, with its own walk cycle. It keeps that face forever. Requires a Mac running Claude Code and the Ground Control daemon.

Ledge is a Markdown notebook that runs the code in your notes. Write the commands for a deploy, a fix or a setup once, with the reasoning beside them, and run each block with a tap. The output appears right under the block. On iPhone and iPad, Ledge opens the notes on your own server: a Linux machine or a Mac running the free Ledge server, reached over SSH. Your notes, shells and commands stay on your machine. RUN ANYTHING • Shell, Python, Node, TypeScript, Ruby, PHP and Redis blocks run with the tools on your server • Add SQL or any other language by naming the command that runs it, such as psql or mysql • Prompt blocks hand a request to an AI agent on your server, such as Claude Code, which can read your notes • Answer a running command's prompts by typing into its output, with ^C, ^D, Esc and arrow keys above the keyboard • Each note keeps its own shell, so a cd or an exported variable carries into the next block • Give a note its own working directory, environment and secrets, kept outside the note • Run a note's blocks on another machine over SSH with one line at the top of the note • Mark a risky block to ask before it runs • A command keeps running on the server after you lock the phone, and its output is waiting when you come back WRITE AND ORGANIZE • Markdown with live preview, tables, checklists and images, including photos from the camera • Link notes to each other, with outline, backlinks and tags panels • Workspaces, folders, favorites and full-text search • Use the same notes from Ledge for Mac and from every phone and iPad you pair PRIVATE AND SECURE • You stay in control of your notes: they live on your own machine, not on our servers or anyone else's • No Ledge account, no sign-up and no third party in between • Sign in with a key made in the Secure Enclave that never leaves the device, or with a password kept in the keychain • Each server's host key is confirmed on the first connection and checked on every one after • Lock sensitive notes with a passphrase • Add a server by scanning the QR code it prints WHAT YOU NEED A Mac or a Linux machine you can reach over SSH, with the Ledge server installed. One command installs it, with no root access, no open port and no background service. The guide in the app walks you through it. Ledge is free and open source.
