AI Email Assistant

BoxieAI started from a simple frustration: important emails get buried across too many inboxes. We built an intelligence layer between the inbox and your attention — it connects several Gmail accounts through secure OAuth, pulls every message into one priority-sorted view, and runs each email through an AI pipeline that classifies it, summarises it and drafts a reply.

Result
3 AI actions on every email

What made it work.

  • 01

    Multi-account Gmail sync over OAuth 2.0, processed in background queues with BullMQ and Redis

  • 02

    GPT-4o pipeline that classifies, summarises and drafts a reply for every incoming email

  • 03

    Daily briefing, custom inbox rules and Paystack-powered subscription billing

The outcome

One dashboard instead of a handful of tabs: what needs action rises to the top, and replying takes seconds instead of reading every thread.
