Zo vs Cluely

Cluely is an AI assistant that provides real-time prompts during virtual meetings, sales calls, and interviews. It runs as an invisible overlay, feeding you suggestions that others can't see, even during screen sharing.

It's a fascinating product with a controversial origin. But it represents a fundamentally different philosophy from Zo.

Different Philosophies

Cluely's thesis: "Help me perform better in this conversation, invisibly."

Zo's thesis: "Give me a computer where I can prepare, build, and own my work."

These lead to completely different products. Cluely optimizes for a single high-stakes moment. Zo optimizes for the weeks of work that surround that moment, from research and preparation to follow-up and long-term knowledge building.

How Zo Approaches This

Zo doesn't provide invisible real-time prompts. Instead, it gives you infrastructure to prepare thoroughly and build systems that compound over time:

Before a meeting

• Research attendees and companies with AI, pulling LinkedIn profiles, recent news, and past interactions from your Gmail history
• Build briefing documents that persist on your server and get richer with every meeting
• Set up a scheduled agent that pulls your Google Calendar events each morning and assembles prep notes automatically
• Draft talking points based on past email threads with the attendees and open items from Linear

After a meeting

• Store notes on your server in your own space where they accumulate into a searchable knowledge base
• Have an agent send follow-up emails through Gmail based on your notes, personalized for each attendee
• Update Linear tickets or Notion pages with action items so nothing slips through the cracks
• Build knowledge that carries into the next meeting with the same person, including what was discussed, what was promised, and what still needs resolution

The work you do on Zo persists and compounds. Each meeting creates artifacts that make the next one better.

The Transparency Question

Cluely's core value proposition is being undetectable. The AI assistance is invisible to the other party. This works well for some scenarios, like navigating a tough interview question or handling objections on a sales call, but it introduces a dependency on real-time prompts that disappears the moment you're in a room without a screen.

Zo takes a different approach: transparent augmentation. You use AI to prepare better, research more thoroughly, and build better systems. The knowledge becomes yours. When you walk into a meeting well-prepared because your Zo agent briefed you that morning, that preparation is genuine and it shows whether or not you have a screen in front of you.

This isn't a judgment on which approach is more ethical. It's a practical difference in what you're left with after six months of use: Cluely leaves you with better conversations. Zo leaves you with a computer full of accumulated knowledge, running automations, and deployed tools.

Beyond Meetings

Cluely solves one problem well: performing better in live conversations. But meetings are a fraction of your working day.

Zo covers the full surface area of your digital workflow. Meetings are one part. The rest includes:

• Hosting websites and APIs on zo.space, from client-facing dashboards to internal tools
• Running scheduled agents that automate recurring tasks like weekly reporting, inbox triage, and data syncing
• Connecting to Gmail, Calendar, Drive, Linear, and Notion to act through the tools your work depends on
• Storing and processing files on a persistent server that remembers everything you've built
• Building custom tools and workflows for use cases that Cluely was never designed to address

For someone whose bottleneck is performing in high-stakes conversations, Cluely addresses that directly. For someone whose bottleneck is managing the entire workflow around those conversations, Zo is the more complete solution.
