Summary

A founder achieved 13 weeks of inbox zero by building a custom AI agent app in Codex that autonomously processes emails, schedules meetings, and handles routine tasks. The system learns from user decisions over time, compounding productivity gains while freeing up time for creative work.

Key Takeaways

  1. Build AI agents that maintain decision history and feedback loops. The system records every action taken (archive, reply, delegate) to improve future filtering and next-action suggestions automatically over time.
  2. Use feed-based architecture to organize work streams. Separate threads for inbox, company updates, and other information flows allow parallel processing and reduce cognitive load when triaging high-volume information.
  3. Implement card-based UI patterns for AI-assisted triage. Each card shows email summary, auto-drafted reply, and proposed next action, reducing decision friction and allowing rapid batch processing of 30+ daily emails.
  4. Give AI agents browser and calendar access for end-to-end task execution. Real-time calendar visibility enables agents to propose meeting times directly and research documents needed for replies without context switching.
  5. Make AI systems that learn from user intent patterns. By watching which emails users mark as interesting vs. archive, systems can refine prompts and filtering logic automatically, creating compounding productivity gains.

I want to show you how I do it. So basically what happens is I have a long running thread called inbox and what people don't really know about codeex is it has an inapp browser in it and what that allows you to do is do all of your work. Any work that you would do in a browser you…
