    dracxterm

    dracxterm

    An Android terminal that runs Linux without root, with an AI assistant

    dracxterm is a terminal for Android. Open it and a shell is waiting. If you want a full Linux, the app installs Debian 13 or Kali inside its own storage, and you work as you would on a computer. The phone does not need root, and there is no account to create. Version 1.1.0 adds claw, an assistant you chat with in the terminal. It uses free model services that need no account, and you choose what it may touch on the AI (claw) page in xset. Programs like nano and htop look right, UTF-8 and CJK display properly, and you get five workspaces plus an extra key row for Ctrl, Alt, Esc and the arrows. Type xset to open the settings, now in six languages. Inside the distro, sudo, apt and dpkg work as usual, and sudo nmap scans. No ads, no trackers, and nothing is sent to the developer. The app goes online to download what you pick, to set up Python and Scrapling for claw's web browsing (you can turn that off), and to send your messages to a model service when you use claw.
