Kanna Mobile vs Ledge Notebook

Kanna Mobile is a companion for the Kanna desktop app for macOS. It lets you follow and steer coding-agent tasks from your iPhone while the work runs on your Mac. Kanna Mobile requires a Mac running the Kanna desktop app. It is not a standalone coding-agent host, and it does not run agents on your phone. WHAT YOU CAN DO • See every task across your repositories, grouped by status and activity • Open a task and watch its terminal and agent output stream live • Send follow-up instructions when an agent stops and asks a question • Start new tasks against a repository and agent of your choosing • Review diffs and file contents an agent has touched • Get a notification when a task needs you TWO WAYS TO CONNECT On your local network, pair directly with your Mac by scanning a QR code. No account, no sign-up, nothing leaves your network. Away from home, cloud access relays the connection between your phone and your Mac. Cloud access needs a Kanna account and is currently invite-only — request one at kanna.build/support. BUILT FOR PEOPLE RUNNING SEVERAL AGENTS Kanna gives every task its own git worktree, branch, and agent session, then moves it through a workflow: implement, review, pull request. Kanna Mobile is the window into that from wherever you ff before lunch, an agent stuck on a question, a reviewyou want to read on the train. Kanna works with the coding-agent CLIs you already have installed on your Mac. A NOTE ON WHAT YOU'LL SEE Kanna is a developer tool. It displays repository names, branch names, task prompts, and raw terminal output from your own machine. Requires the Kanna desktop app for macOS, available at kanna.build.

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.
