Extra Thursday

An AI-native inbox that drafts, tracks and clears your Gmail

Instant inbox discovery

Extracts insights from thousands of emails at once so you can find the one thread that matters without scrolling or building search queries by hand.

Open-loop tracking

Treats email as a database of decisions, tracking unfinished threads, surfacing action items and holding context across many conversations.

AI drafting in your voice

Generates replies and follow-ups that match how you write, from detailed technical answers to brief, courteous nudges.

One-click review and send

Drafts land ready for you to read, edit and dispatch, so responding stays a fast, human-approved step rather than an auto-send.

Strengths & Pros

+Focuses on open loops and action items rather than just summarising mail
+Drafts in your own voice and keeps you in the loop with one-click review before sending
+Careful prompt on getting started free removes the barrier to trying it
+Works with Gmail, so there is no migration of your existing mailbox
