Triage lanes
How AI assigns Reply, Schedule, FYI, and Done lanes
The four lanes
Command Inbox organizes mail into four lanes based on a single question: what kind of work does this thread need?
| Lane | Icon color cue | When AI assigns it |
|---|---|---|
| Reply | Action needed | Questions, requests, decisions, follow-ups requiring a written response |
| Schedule | Calendar-centric | Meeting proposals, invite requests, reschedules, availability asks |
| FYI | Low urgency | Newsletters, notifications, receipts, CC-only informational mail |
| Done | Archived | Threads you archived with E — removed from active lanes |
Lanes appear as tabs at the top of the thread list. Only one lane is active at a time.
Priority within lanes
Each thread also has a priority: high, medium, or low. Higher-priority threads sort toward the top within a lane. Priority reflects urgency and sender importance inferred by the classifier.
Scheduling intent
Threads in the Schedule lane often include structured scheduling intent:
- Proposed date/times mentioned in the email
- Attendee email addresses
- Suggested duration
- Confidence score
This data powers the M meeting workflow — you do not need to re-read the thread to find times.
How classification updates
Initial indexing
When you first connect Google, the app runs a two-phase index:
- Immediate — classifies the latest ~50 INBOX threads so lanes are usable quickly
- Background — indexes your full INBOX for semantic search (progress banner)
Advanced search (Mod+Shift+F) queries Gmail via Corsair anytime — no index required.
Realtime webhooks
When new mail arrives (or existing threads change), Gmail push notifies the app:
- Corsair syncs the thread to its cache
- AI re-classifies the thread
- Embedding is updated for semantic search
- Pusher pushes an update to your browser (or polling refreshes within 5s)
You may see a thread move between lanes without refreshing the page.
Manual lane changes
| Action | Effect |
|---|---|
E (archive) | Moves thread to Done lane; archives in Gmail |
| Restore from Done | Command palette or API — pick target lane |
Archiving is the primary way users move mail to Done. The AI does not auto-archive.
Lane filters in search
Advanced search (Mod+Shift+F) accepts an optional lane filter so you can query Gmail history scoped to, for example, all Schedule-lane threads from a specific sender.
Tips for evaluators
- Send yourself a test email with explicit scheduling language — watch it land in Schedule within ~30 seconds
- Send a newsletter-style email — expect FYI
- Send a direct question — expect Reply
- Archive with
E— thread moves to Done
