ZetaChain Introduces TwoThumbs: AI Chat via iMessage and SMS
Feb 4, 2026
ZetaChain Team
TwoThumbs is an AI chat app for texting AI characters, companions, and assistant bots via iMessage and SMS. Switch models without losing context.
Our mission is to build the universal layer for AI and Web3 so apps can run across chains and models, keep private memory, and monetize without infrastructure.
Following our release of ZetaChain 2.0, we’re excited to share TwoThumbs, a new AI chat experience that lets you text AI characters and AI agents directly through iMessage and SMS with no app install required.
It’s built on the same infrastructure as Anuma’s private chat experience and uses our AI Portal to route across models from one place, so you can get better AI interaction without juggling multiple apps.

What is TwoThumbs?
TwoThumbs is a “text-to-AI” conversational AI experience: you send a message, and the AI replies inside the messaging apps you already use. You don’t need to switch between apps or “start over” every time.
Here’s what you can do with TwoThumbs:
Some people use it for companion-style chats (AI girlfriend / AI boyfriend). Others use it as a personal assistant or coach.
Create an AI agent that helps you plan, research, and make decisions while you’re on the move
Use an assistant bot in group chats to settle debates, plan trips, or generate ideas
Keep a conversation thread that stays useful over time instead of resetting every session
Switch between AI models without losing context

Humanize AI without losing control
Most AI tools still feel like you’re talking to a website. TwoThumbs is built to humanize AI by putting it into the interface you already use every day: texting. The result is faster, more natural AI conversations while keeping you in control of what you share.
Why build this on ZetaChain?
Messaging is one of the most universal interfaces on the internet. But most AI products still force users into separate apps and silos where context gets trapped and portability breaks down.
ZetaChain was built to solve fragmentation first across blockchains, and now across the AI stack. With ZetaChain 2.0, we’re applying the same unification thesis to AI so applications work across models and chains while keeping user memory private and portable.
What’s next?
TwoThumbs is a simple example of an AI product that “just works” over text. We’ll be sharing more soon about how developers can build experiences like this.
