Show HN: Playground for AI email triage with a dynamic interface and chatbot

After a week off, I came back to hundreds of unread emails.
I wanted a way to figure out what actually mattered without spending hours.
So I built a small AI prototype that: - Finds urgent and important messages - Summarizes long threads - Lets you interact with your inbox in a more visual way
Right now, it’s just a playground using a realistic sample inbox (hardcoded data). You can try it here: https://catchupinbox.com/playground
It has: - A dynamic email/thread interface - An AI chatbot that works directly within that interface
Stack: Next.js, hexagonal architecture, OpenAI (LLM-agnostic). Privacy-first — no real emails are used in this demo.
I’m curious: - Does this approach make sense to you? - What would make this genuinely useful? - Any edge cases or workflows I should consider before adding Gmail/Outlook support?

The is what the AI produces: a small set of urgent items + short summaries.
This demo runs entirely on hardcoded data — nothing from your real inbox.
Gmail and Outlook support are definitely the next big step — the main challenge is figuring out the best way to process everything while keeping privacy intact.
If you use Gmail/Outlook heavily, I’d love to hear: - What kind of “important” criteria you’d want it to detect automatically - Any edge cases where a tool like this might get it wrong
That input will help me shape the integration roadmap.
Do you think you’d want to configure those “important” rules yourself, or would you prefer the AI to just learn your habits over time?
