+## TUI
+
+Launch with `axp tui`. The terminal UI provides a full interactive experience with five tabs:
+
+| Tab | Key | Description |
+|-----|-----|-------------|
+| **Daily** | `1` | Browse personalized papers with detail panel |
+| **Search** | `2` | Search arXiv interactively |
+| **Lists** | `3` | Manage reading lists and track status |
+| **Notes** | `4` | Browse and filter paper notes |
+| **Prefs** | `5` | Manage categories, keywords, and AI settings |
+
+**Key bindings**: `Enter` open detail / `l` like / `d` dislike / `s` summarize / `t` translate / `n` note / `a` add to list / `r` refresh / `q` quit

-**Recommendation Algorithm** — Papers are scored using a weighted combination of:
-- Content similarity (50%) — TF-IDF cosine similarity to liked papers
-- Category matching (20%) — Priority-weighted category overlap
-- Keyword matching (10%) — Weighted keyword presence
-- Recency bonus (5%) — Papers published within the last 30 days

 ## AI Providers
 
-AI features (summarization and translation) work by calling external CLI tools via subprocess. No API keys are stored in the application — each tool manages its own authentication.

-### How it works
+## Architecture
 
-1. The active provider receives a structured prompt requesting JSON output
-2. The CLI tool processes the prompt using its own API key / local model
-3. arXiv Explorer parses the JSON response and caches the result in SQLite
-4. Subsequent requests for the same paper return instantly from cache

-Summarization and translation are available in both CLI (`axp show -s`, `axp translate`) and TUI (`s` / `t` keys in paper detail).
