Join existing or new meetings
Paste a Google Meet link or start a new meeting, then dispatch a specialist into it. The site says this flow also works with Zoom and Teams.
gstack
gstack adds Garry Tan’s open-source specialist personas to live meetings as voice bots. It supports Google Meet, with support also mentioned for Zoom and Teams, and runs through a bring-your-own-brain workflow using a local coding-agent session.
What gstack is
gstack joins live meetings as a voice bot version of Garry Tan’s open-source gstack specialists. The product lets you paste a meeting link or create a meeting, then choose a specialist or preset team to participate in the call.
According to the site, each specialist joins in character with a voice and 3D avatar, can listen and respond in real time, and can be recalled when no longer needed. The product is aimed at meetings where opinionated specialist feedback is useful, such as pair programming, standups, design reviews, office hours, and other team discussions.
The site also describes a bring-your-own-brain model: the specialist is powered by a coding-agent session on your own machine, such as Claude Code, Codex, or Cursor. The site says that keeps the repo, context, and conversation on your side while the agent handles the reply logic for the call.
Core capabilities
Specialist roster and team presets
Choose an individual specialist or one of six team presets. The roster includes 19 specialists, such as CEO, CSO, QA Lead, and Release Engineer.
Voice, avatar, and recall behavior
Each specialist shows up with its own 3D avatar and voice, and can listen, respond, and leave when recalled.
Bring your own brain
Specialists are powered by a coding-agent session on your machine, using tools such as Claude Code, Codex, or Cursor as the “brain.”
Local-session data handling
The site says the bot only sees what you dispatch through the session, and that your repo, context, and conversation stay on your side rather than on the vendor’s servers.
AgentCall meeting transport
The product is wired through AgentCall, which provides the meeting plumbing for live voice, barge-in, interrupts, and a live 3D avatar tile.
Where it fits
Individual expert review
Use a single specialist when you want one focused perspective in a live discussion, such as a CEO, CSO, QA Lead, or DX role.
Multi-role feedback sessions
Use a preset team when a meeting needs several perspectives at once, such as Founding, Design, QA & Ship, or DX.
Product and engineering meetings
Bring the bot into standups, design reviews, pair programming, or office hours where a real-time participant can question assumptions and push the discussion forward.
Local-agent workflows
Use the local brain model when you want the reply logic to come from your own coding-agent session rather than a hosted remote agent.
Temporary live participation
Choose gstack when you need a meeting participant that can join, respond, and then be recalled without leaving the call open indefinitely.
Pros and Cons
Pros
- Supports live meeting participation rather than text-only prompts.
- Covers Google Meet, Zoom, and Teams in the published site copy.
- Offers both single specialists and curated team presets, which gives some flexibility in how feedback is delivered.
- Uses the user’s own coding-agent session as the brain, which the site says keeps repo and conversation data on the user’s side.
- Includes voice, avatar, barge-in, and recall behavior for a meeting-native interaction model.
Cons
- The public pricing page was unavailable in the collected sources, so the pricing model is not clear from the site.
- The source material is light on setup, output formats, and team administration details beyond the basic join-and-dispatch flow.
- The product depends on a local coding-agent session as the brain, which may not fit users who want a fully hosted setup.
FAQ
How does gstack work in a meeting?
gstack is presented as a way to bring Garry Tan’s gstack specialists into live meetings. You paste a Meet URL or start a new meeting, then choose a specialist or a preset team and dispatch it through your coding-agent session.
Which meeting platforms and coding agents does it support?
The site says it works with Google Meet, Zoom, and Teams. It also says the specialists are powered by a coding-agent session such as Claude Code, Codex, or Cursor running on your machine.
What does “bring your own brain” mean?
The byob page says a brain is a coding-agent session on your laptop. It only sees what you dispatch through it, and when you close it, it stops; nothing persists on the server beyond the dispatch history shown in the dashboard.
Can I use a single specialist or a team preset?
The home page describes solo use or curated teams such as Founding, Design, QA & Ship, and DX. That suggests the product is meant both for single specialists and for grouped meeting roles.
Is pricing available on the site?
The pricing URL currently returns a 404/offline page, so the public site does not show active pricing details in the collected sources.
