jredville/tui-canvas

tui-canvas is a persistent, per-session markdown canvas that integrates with Claude Code. It packages a daemon (owns sessions and broadcasts state over a Unix socket), a Bubbletea TUI client (live-synced views; suitable for tmux/split panes), and a Claude Code plugin (auto-registers sessions and lets Claude push content via skills). Intended for developers using Claude Code in terminals who want notes, summaries and code snippets kept alongside sessions. Key features: per-session tabs, live synchronization across multiple TUI instances, push skills (/tui-canvas:tui-canvas and /tui-canvas:tui-clear), CLI for append/clear/list/restart, keyboard search/navigation, and a newline-delimited JSON socket protocol at ~/.local/share/tui-canvas/tui.sock. Supports Linux and macOS (amd64/arm64); install via the Claude plugin marketplace and run tui-canvas to open the UI.
