A fast, native desktop RSS reader with a resizable 3-panel layout, built-in Reddit comments, AI summaries, text-to-speech, and a collapsible bar mode. Built with Tauri 2 and React 19.
The interface is split into three independently resizable columns with drag handles between them:
| Panel | Default Width | Content |
|---|---|---|
| Sources (left) | 18% | Feed tree organized by type, folders with drag-and-drop, unread counts, favorites, read later |
| Feed (center) | 32% | Article list with pagination, time grouping, 3 view modes (normal, compact, cards) |
| Reader (right) | 50% | Full article reader, AI summary, TTS, highlights, web view toggle, Reddit comments |
Each panel can be closed individually -- it collapses into a thin clickable strip. Toggle panels with keyboard shortcuts 1, 2, 3. Panels resize freely by dragging the handles between them.
Click the collapse button in the title bar and the entire app shrinks into a slim floating bar that stays on your desktop. The bar displays:
- Unread count, favorites and read-later badges
- Live weather with auto-detected geolocation (temperature + weather icon)
- Live clock with date
- Pin button to keep the bar always on top of other windows
One click expands back to the full 3-panel layout.
Add any subreddit by typing r/subredditname in the add feed dialog. SuperFlux:
- Shows comment count on each post in the feed list
- Fetches live comments from Reddit's API when reading a post (sorted by best, up to 30 comments)
- Displays author, score, and relative timestamp for each comment inline
- Falls back to cached comment data if the API is unavailable
