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
- Stack
- Next.js, NestJS, OpenAI GPT-4o

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.
