Arx is an AI inbox client for people who want a quieter inbox without handing control to a black box.
It is built around a simple idea: email should feel lighter. The app helps you clear low-signal mail, draft replies faster, and keep the final decision in your hands.
Disclaimer: Arx is an experimental proof-of-concept app, not a production-ready standalone product. This work is intended to be integrated into the Char repository.
- Your inbox should get quieter, not louder.
- AI should suggest work, not silently do work.
- Triage and reply should live in the same place.
- Fast, editable drafts are better than robotic auto-send.
- Local control matters when your email is involved.
Arx is for people who spend too much time sorting, skimming, and rewriting email. Instead of making you bounce between filters, folders, and half-finished drafts, Arx puts the core workflow in one desktop app:
- review what matters
- clear what does not
- generate reply drafts
- confirm every real mailbox action
- Connect a mail account.
- Sync your inbox into Arx.
- Generate an AI review batch.
- Approve the suggestions you actually want.
- Edit or send reply drafts from the built-in composer.
Arx is designed around suggest + confirm. Archive, read/unread changes, stars, move-to-inbox actions, and reply drafts stay explicit. Nothing important should happen behind your back.
- Gmail
- Outlook
- IMAP / SMTP
- AI-assisted inbox cleanup
- AI-assisted reply drafting
- Rich-text email editing
- Local message cache for a fast desktop experience
- Message data is cached locally on your machine.
- Account secrets are stored in your OS credential store.
- AI suggestions are reviewable before they touch your mailbox.
- Draft replies stay editable before send.
Arx is in early preview as an experimental proof-of-concept.
The current build already has the desktop app shell, local cache, AI review queue, and rich-text reply composer. Live Gmail, Outlook, and IMAP syncing are still being finished, so this version should be treated as a product preview rather than a fully production-ready mail client.
Most email software forces a bad tradeoff. You either do everything manually, or you let automation act with too little context and too much confidence.
Arx takes a stricter approach: let AI do the reading, grouping, and drafting, but keep the human in charge of the mailbox.
A lot of the thinking behind Arx was shaped by Horseless Carriages.
