Shapes Wants to Put AI Characters in Your Group Chats, Not Replace Your Friends

There’s a new app called Shapes that’s trying to solve a problem I didn’t know I had: group chats that go silent because nobody wants to send the first message. The solution? AI characters that just jump in and keep things moving.

Shapes is emerging from stealth mode with $8 million in seed funding, led by Lightspeed. The pitch is straightforward—imagine Discord, but some of the participants are AI. These aren’t the passive bots you summon with a slash command. They’re labeled as “Shapes,” have their own personalities, and can decide when to speak up.

Founders Anushk Mittal and Noorie Dhingra started the company back in 2022. They’ve already grown to over 400,000 monthly active users, with three million user-created Shapes floating around in group chats. That’s a lot of AI personalities.

Why group chats need AI nannies

Mittal makes a fair point: most of our online communication happens in group chats, not one-on-one. Yet every AI interaction we have is private and isolated. “That’s not really how humans collaborate,” he told TechCrunch. So why not just let AI into the group chat where it already has context?

The app tries to tackle what they call “AI Psychosis”—the idea that prolonged one-on-one chats with AI companions can make people paranoid or delusional. By keeping the AI in a social context with real humans, the theory goes, you avoid that spiral. I’m not entirely convinced this solves the deeper problem, but it’s a more interesting approach than just slapping a chatbot on a website.

How it actually works

When you sign up, you pick your interests and get recommended group chats. Many of the existing chats are built around fandom—people deep-diving into subcultures and meeting others who share their obsessions. The AI characters act as conversation starters and facilitators.

The key differentiator here is that Shapes have “free will.” They don’t need to be summoned. They can message whenever, which means you never have to worry about getting left on read. That’s both clever and slightly unsettling.

ChatGPT already lets you add AI to group chats, but those are mostly for planning or brainstorming. Shapes is purely social—it’s about hanging out, not getting work done. That’s a meaningful distinction.

The numbers and what they mean

Shapes has seen a sixfold increase in users since the start of 2026, driven entirely by word of mouth. Thousands of users spend two to four hours a day in the app. That’s serious engagement, but it raises questions about whether this is healthy or just another dopamine trap.

The $8 million round also includes AI Capital Partners, AI Grant, and some angels. The money will go toward development and user acquisition. That’s standard startup speak, but the real test will be whether Shapes can grow beyond the “obsessively online” demographic Mittal describes.

My take

I’ve seen a lot of AI social experiments come and go. What makes Shapes different is that it’s not trying to replace human interaction—it’s trying to augment it. Whether that actually works or just creates more noise in already crowded chat apps remains to be seen.

The “AI Psychosis” angle feels a bit like marketing spin, but the underlying insight is solid: one-on-one AI companions are isolating by design. Group chats are inherently social. Putting AI in that context might actually be healthier than the alternatives.

Still, I wonder about the long-term effects. If AI characters are always the ones keeping conversations alive, do people stop learning how to initiate? Is the AI doing the social heavy lifting while humans just coast? Those are questions the founders will need to answer as the app scales.

For now, Shapes is an interesting experiment in blending AI and human social dynamics. It’s not for everyone, but if you spend hours in group chats already, you might find the AI participants more helpful than annoying. Or you might just mute them. That’s the beauty of free will—even for the bots.
