 ## Why difi?
 
-- ⚡️ **Blazing Fast** — Built in Go. Starts instantly.
-- 🎨 **Semantic UI** — Split-pane layout with syntax highlighting and Nerd Font icons.
-- 🧠 **Context Aware** — Opens your editor (nvim/vim) at the exact line you are reviewing.
-- ⌨️ **Vim Native** — Navigate with `h j k l`. Zero mouse required.
+- ⚡️ **Instant startup** — Built in Go, no background daemon.
+- 🎨 **Structured review** — Tree view + side-by-side diffs.
+- 🧠 **Editor-aware** — Jump to the exact line in `nvim` / `vim`.
+- ⌨️ **Keyboard-first** — Designed for `h j k l`, no mouse.
+
+## Why not `git diff`?
+
+- `git diff` is powerful, but it’s optimized for output — not review.
+- difi is designed for the *moment before you push or open a PR*:
