Open-source voice agents — CEO, YC partner, QA lead and more — that join your Google Meet, critique your screen, and drop notes in chat.
gstack-meeting.com is a demo of AgentCall that puts specialist AI voice agents — a CEO, CSO, QA lead, a Y Combinator-office-hours partner and roughly 15 more personas — into a live Google Meet as 3D-avatar participants. The agents open in-persona, take turns, critique whatever you share on screen out loud, and post structured notes in the meeting chat; the YC partner opens with 'what are you working on, and who actually wants it?', while the senior-designer persona scores your page and drops points in chat. The platform is MIT-licensed and the personas are Garry Tan's open-source set, credited under MIT. Crucially, the 'brain' of each agent is your own local coding-agent session — Claude Code, Cursor, or Codex on your laptop — so audio and files never leave your machine; only transcripts of calls you start are used.

Gstack Meeting Agents are open-source voice agents designed to enhance Google Meet experiences. They include roles such as CEO, YC partner, and QA lead, which join your meetings, provide critiques on shared screens, and deliver insightful notes directly in the chat for improved collaboration.
Gstack Meeting Agents utilize advanced AI technology to participate in Google Meet sessions. These agents can take on roles such as a CEO, YC partner, or QA lead, enabling them to provide relevant feedback based on their simulated expertise. For instance, a QA lead agent can analyze a software demo and deliver constructive critiques about the application’s functionality.
Gstack Meeting Agents function by integrating multiple AI specialist personas into Google Meet calls, providing real-time critique, structured notes, and domain-specific expertise. This innovative tool enhances meetings by simulating expert feedback, aiding in preparations like YC interviews, product reviews, and startup demos.
Gstack Meeting Agents revolutionizes virtual meetings by introducing AI-driven personas that mimic real-life experts. These personas—such as a CEO, designer, or YC partner—join Google Meet calls as 3D avatars. They actively engage in discussions, offering critiques based on shared screens and providing feedback as if they were actual participants.
For instance, during a YC Interview Prep session, you can practice your pitch with a YC-partner persona. This agent will ask real questions that venture capitalists typically pose, allowing you to refine your pitch effectively. Similarly, if you're conducting a Product & Design Review, the designer persona can assess your UI or landing page in real time, offering valuable insights on user experience and design elements.
Additionally, Gstack facilitates Startup Feedback Sessions, where a simulated executive team reviews your demo before you present it to real stakeholders. This practice helps you anticipate questions and refine your presentation. The tool also features Async Meeting Notes, where each persona contributes written notes and scores in the chat, ensuring that all feedback is documented without needing a dedicated notetaker.
The use of a Local Brain ensures that sensitive audio and files remain on your own machine, enhancing privacy and security during meetings. Users can even create Custom Agents tailored to their specific needs, leveraging the flexibility of AgentCall to build personas with domain-specific expertise.

Gstack Meeting Agents transform virtual meetings by incorporating AI specialists that mimic real-life professionals. Each persona has expertise tailored to various meeting needs, such as a Chief Executive Officer (CEO) offering strategic insights or a Quality Assurance (QA) lead evaluating product demos. This diversity in specialist personas ensures that discussions are robust and informed.
Gstack seamlessly integrates with Google Meet, allowing these AI agents to participate as 3D avatars. This integration enhances user experience by making virtual meetings more interactive and engaging. For instance, during a brainstorming session, a designer persona can visually represent ideas, making complex concepts easier to understand.
One standout feature is the agents' ability to critique shared screens during meetings. They analyze presentations or documents and provide constructive feedback in real-time. This capability helps teams refine their ideas instantly, promoting a collaborative environment similar to in-person discussions.
Each Specialist Persona contributes to the meeting chat by leaving written notes and scores, ensuring that valuable insights are captured. This feature is particularly useful for participants who may miss verbal feedback, allowing them to review detailed notes post-meeting for clarity and follow-up actions.
