AI YC interview with Gstack agents - AI specialists that join your Google Meet and gives feedback

Garry Tan's open-sourced gstack specialists — CEO, CSO, QA Lead, a YC-office-hours partner and 15 more — join your real Google Meet as voice bots with 3D avatars. They open in-persona, take turns, critique your shared screen out loud, and drop notes in chat. Free, MIT, and the brain is your own coding-agent session. Built on AgentCall.

Maker here 👋 I built gstack to answer one question: what does a meeting feel like when AI agents are participants, not notetakers? So they join your Google Meet as voice bots. The YC-partner persona opens with "what are you working on, and who actually wants it?" — and honestly it's uncomfortable in the best way. Share your screen and the senior-designer persona scores your page out loud, then posts the points to chat. Three things I care about: 1. Honest open source — the whole platform is MIT (github.com/pattern-ai-labs/gstack-joins-meeting), and the personas are Garry Tan's, credited and MIT. 2. The "brain" is YOUR coding-agent session (Claude Code / Cursor / Codex) on your own laptop — no audio or files leave your machine, just transcripts, only for calls you start. 3. gstack is really a demo of AgentCall (agentcall.dev) — the API that lets any agent take a seat in a meeting. If you build agents, you can put yours in a call too. Try it free, no card: gstack-meeting.com. I'll be here all day — would love your feedback.

Hey all 👋

Quick update: we’re seeing heavy usage and the shared brain pool is currently at capacity.

For now, please clone the repo, create your own brain, and run it locally.

Also, this is a self-learning agent. If you run into problems, just ask it to resolve them and it will work on fixing them.

Cool stuff 🚀, Don't know how you pulled this off but getting gstack agents to join meetings is like a major upgrade to 's gstack. Even though i was stuck in the shared queue for some moment, i still had it running using my own claude code as brain, Had a call with the gstack CEO and I'm already loving it. 😄

Having agents critique a shared screen in real time is a strong idea. Can each persona retain context across multiple meetings, or does every call start fresh?

 Brain is your Claude Code session. If you resume the same session, it will retain all the previous context.

 Nice, very cool product, great work!
