The Norn Terminal UI provides an interactive pull-request review workspace in the terminal.

Launch modes
From a supported Git repository, run either command:
norn
norn-tui
Norn resolves the current repository from its Git remote and opens its pull requests. To start from the configured repository list instead, use:
norn-tui --workspace
The TUI runs a readiness preflight before opening. Use norn doctor to inspect
and resolve failures rather than routinely skipping the preflight.
Main workflow
The interface is divided into repository, pull-request, and detail areas. The detail view can show pull-request information, AI review output, or the diff.
Common keys:
j/kor arrow keys: move through the active list;Tab: move focus between panes;Enter: open the selected pull request;g: open or close the diff view;u: switch between unified and side-by-side diffs;i: switch the image side for supported image changes;v: toggle pull-request and AI-review detail;a: start an AI review;y: copy AI review output;c: compose a local comment draft;p: publish drafts;x: discard drafts;f: cycle the pull-request filter;r: refresh the active view;s: open AI provider settings;qorEsc: quit.
AI settings
The settings screen lets you select Claude or Codex and choose the model and
reasoning effort used by TUI reviews. Use j / k to select a setting, arrow
keys to change it, Enter to save, and Esc to cancel.
Credentials
The TUI resolves provider credentials from the OS keychain first, then from
environment-variable references in ~/.config/norn/config.toml, and finally
from the standard provider environment variables.
