sunset.ai

Sunset is a team messaging app with unlimited AI memory. Each channel remembers its full history forever - powered by Supermemory. No context limits, no cross-channel leaks.

Inspiration

Slack added AI. ChatGPT added group chats. But both have the same problem: AI either loses context over long conversations, or has no personalization in group settings. Sunset solves this by giving each channel its own persistent AI memory built on Supermemory.

What it does

Sunset is a team workspace where AI actually remembers. Create workspaces, invite teammates, and chat in topic-based channels. Each channel has its own isolated AI memory powered by Supermemory - so #marketing discussions don't leak into #engineering. Connect Notion or OneDrive to give the AI even more context about your team's work.

How I built it

Forked supermemory.chat and transformed it from a single-user app into a multi-user workspace platform. Key changes:

  • Schema redesign for workspaces, members, and channels
  • Per-channel memory isolation using Supermemory containerTags
  • Workspace-level Supermemory Connectors for Notion/OneDrive integration
  • Lots of UI polish for smooth multi-user UX

Built with Next.js, Drizzle ORM, Supermemory API, and deployed on Vercel.

Challenges I ran into

  • Massive codebase: Unfamiliar with Next.js, so I learned just enough to make each change, then moved on. Rinse and repeat.
  • Frontend debugging: Not a React expert, so UI bugs ate more time than expected. Worth it though - the final UX is smooth.
  • Life happened: Late final exam, got sick for 2 days, power outage. Ended up working 24 hours straight on the last day to ship.

Accomplishments that I'm proud of

  • Shipped a working, deployed app that anyone can try
  • Built a full-stack product with technologies I'd never used before (Next.js, Drizzle) in 4 days - while sick and dealing with a power outage
  • Pushed through to the end despite everything. This is already a win.

What I learned

  • Always plan for the unplanned
  • Grinding together is way more fun than alone, i loved the DevHouse vibe

What's next for sunset.ai

  • MCP tools support (Calendar, Linear, etc.)
  • Smoother real-time multi-user messaging
  • Better UI/UX polish
  • Team analytics - see what topics your team discusses most, identify knowledge gaps
