Tech-Spookezz/ReachInbox.AI — reverse-engineered prompt

Build me a simple ReachInbox style app that connects to both Gmail and Outlook, reads a user’s emails, understands the email context with AI, and helps send the right reply.

I want users to sign in with Google or Microsoft, see their profile and mailbox, open individual messages, view drafts where available, and send replies. The AI should classify each email into simple labels like interested, not interested, or needs more information, then generate a short reply based on that label and the email content. Add a way to send one reply or send replies to multiple recipients.

Use a Node and Express backend, OpenAI for the email understanding, Google APIs for Gmail, Microsoft Graph for Outlook, Redis and BullMQ for background email sending jobs. TypeScript would be preferred if it fits cleanly. Include a basic frontend so I can test the flow, plus environment variables and clear run instructions. Look up current docs online if needed.
