Zoom AI Companion 3.0 Just Expanded to Microsoft Teams and Google Meet

The new version doesn't just watch your Zoom meetings. It follows you to your other calls too.

Zoom launched AI Companion 3.0 this month with a feature most people missed: it can now capture and transcribe meetings on Microsoft Teams, Google Meet, and in-person meetings. Not just Zoom. If AI Companion is on your account, Zoom's AI now rides along to every call you take, on every platform.

That changes the game. Millions of people use Teams for internal calls and Zoom for clients, or flip it around. Most assumed those were separate worlds. Now one AI layer sits across all of them, piping summaries and transcripts back to Zoom's servers no matter which app hosted the call.

What AI Companion 3.0 actually does

The full feature set now includes:

• Automated transcription and notes across Zoom, Teams, Google Meet, and in-person meetings
• A "My Notes" feature that merges your handwritten notes with AI-generated transcripts
• Agentic search across your entire meeting history, connected to Google Drive, OneDrive, and other apps
• Tools to convert notes into emails, project updates, and action plans from templates
• AI avatars that can represent you in meetings when you're not there

That last one deserves its own conversation. But the bigger story is the aggregation. AI Companion 3.0 wants to build a running memory of your work life. Every meeting. Every platform. Your documents too.

Where the data goes

Everything AI Companion processes routes through Zoom's cloud. That was always true for Zoom calls. Now it's true for your Teams and Google Meet calls too.

Zoom's current policy says content may be shared with sub-processors. Those are third-party companies that help run the AI features. According to Zoom's own documentation, vendors can hold onto that data for up to 30 days for "trust and safety" purposes.

Zoom says it won't use meeting content to train AI models without explicit consent. That's the policy today. In 2023, Zoom quietly updated its terms of service to language that appeared to allow exactly that, no consent needed. Public backlash forced a reversal. But it happened. And policies change.

The knowledge graph problem

The most important part of AI Companion 3.0 isn't any single feature. It's what happens when you combine them.

A transcript from one meeting is a data point. Summaries from ten meetings reveal patterns. A searchable memory spanning months of conversations, documents, emails, and project updates, one that can draw connections across all of it, is a fundamentally different system.

That's what Zoom is building. Great if you trust every layer of the stack. Less great when you think about a sub-processor getting breached. Or leaving a company that owns the account. Or a legal team pulling records. Or another quiet policy update.

The consent model is thin too. Participants usually see a small badge in the meeting UI saying AI Companion is active. Most people click past it without reading. And if you join someone else's Teams call where they've connected Zoom AI Companion to their account, you might not see any notice at all.

The avatar question

AI Companion 3.0 also ships AI avatars. Photorealistic digital versions of you that can attend meetings on your behalf, with synced expressions and lip movements matched to audio.

Zoom added watermark badges to flag AI avatars. Security researchers have already shown those watermarks can be spoofed in seconds.

The real problem is normalization. Once AI-generated participants become normal in meetings, the visual cues people rely on to gauge trust in video calls stop working. That's a social engineering risk that goes far beyond meeting privacy.

If you want your notes to stay yours

AI Companion's expansion to competing platforms makes the picture clear: in the cloud model, your meeting data flows to whoever owns the AI layer. Doesn't matter which video app you're on.

Local transcription works differently. Audio gets processed on your machine, by a model running locally. Nothing leaves your computer. No cloud to breach. No sub-processor to worry about. No policy update that changes the rules after the fact.

MeetingVault does exactly this. It captures audio from Zoom, Teams, Google Meet, or any other app on your Mac, transcribes it locally, and throws away the audio. What remains is your transcript, on your device, going nowhere.

You can't control what Zoom's AI captures when someone else has it turned on. But your own notes don't have to live in someone else's infrastructure.
