From a busy inbox to a clearer day
A small routine.
A lot less checking.
Understand it. Then decide.
AI prepares important updates and proposed tasks. Open the original message beside the summary, and approve changes yourself.
Give your day some breathing room.
Keep one-time tasks and repeating classes separate. Plan focused work in Today and see your saved schedule across the month.
Built around your day
Useful structure.
Without the clutter.
- A daily overview
- A few important updates up front, with the full briefing a click away.
- Tasks that fit real life
- One-time work, repeating schedules, completion checklists, and a shared timeline.
- Messages with context
- Go from a summary to its source, instead of wondering where a suggestion came from.
- A choice of AI
- Local Ollama, or optional Claude and OpenAI using your own key. API use sends message content to the selected provider and may incur charges.
REI OS · 0.1.0 Beta 2
Make a little room
on your desktop.
The real desktop app, with your own messages and saved plans. These are early beta builds; the browser demo above stays separate and uses sample data.
Windows is unsigned; the Mac beta is ad-hoc signed and not Apple-notarized. Your system may block the first opening. Release notes and checksums ↗
For AI, choose local Ollama with an installed model, or configure your own supported API key in Settings. Accounts and models are not included in the download.

An honest preview
Still growing. Already worth exploring.
REI is a desktop app in development. This browser demo demonstrates its planning workflow using sample data and prewritten summaries; it does not run the desktop backend or a live AI model.
Email supports HIZ, secure provider discovery, and Google/Microsoft browser sign-in. Google sign-in is currently limited to invited beta testers, and university account policies may require approval. Teams, cloud sync, and a full conversational assistant with searchable memory are not available in this preview. Windows and Apple Silicon Mac opening and email sign-in have been tested by the creator; wider device testing is ongoing.
