Build for Chat

Build for Chat

Every generation has a dominant platform:

🌐 Browsers unlocked the web.

📱 App Stores unlocked mobile.

🖼 Mini-apps cracked open embedded experiences.

Now we’re at the start of the next cycle: Agents in Chat.

For the first time, chat is not just about blue or green bubbles:

💳 Agents have the ability to transact

🧩 Every message is programmable.

👥 Every group is a distribution channel.

🪪 Every identity is flexible and composable.

The largest surface area on the planet — chat — is now open.

The App Store moment is happening again, but this time inside DMs and Groups.

Why this matters:

This isn’t about making better bots. It’s about creating new behaviors that never existed before.


UX Best Practices for Building in Chat

1. Messages Are the UI

2. Design for Groups First

3. Keep It Frictionless

4. Be Reactive in Real Time

5. Make Identity Playful

6. Invisible Money Flows
