+A full-screen TUI opens and shows each backend's status in a table — **unavailable** (red, name dimmed: not installed and no server running), **installed** (orange), or **running** (green, when an external server is already accepting connections on its configured port). From the menu you can:
 
-- **Convert books…** — process the `input/` directory with a ready backend (it reads the backend's `server.json` / `voices.json` so you pick the model and voice from menus), or
+- **Convert books…** — process the `input/` directory with a ready/running backend (it reads the backend's `server.json` / `voices.json` so you pick the model and voice from menus), or
 - **Set up a backend…** — clone, build, and configure a backend end-to-end (audio.cpp, qwen, faster), or
-- **Modify a backend…** — regenerate its config (a new `server.json`, rebuild `voices.json`, change ports/speaker).
+- **Configure a backend…** — regenerate its config (a new `server.json`, rebuild `voices.json`, change ports/speaker).

 Everything the TUI does can also be scripted with flags: `python audiobook.py --backend audiocpp --model higgs --voice narrator`, or `python -m backends.audiocpp --families higgs_audio_tts --clone --build-backend cuda`.
