About Text.ai
Summary
Text.ai builds Alfi, an AI agent that lives inside group chats on SMS, WhatsApp, and iMessage. Alfi learns each member's preferences, humor, and history to help the group plan events, find places to eat, set reminders, and create images, replacing the back-and-forth coordination that normally falls on individual people. It requires no download or setup, operating as a persistent presence in existing conversations.
Go-to-market
Consumer friend groups adopt Alfi by adding it directly to an existing chat thread on platforms they already use, making onboarding entirely self-serve with no app install required.

AI in your group chats
We're building the first AI agent that thinks like a group. While everyone else is stuck with boring individual chatbots, we've cracked the impossible: AI that reads the room, understands each person, and creates custom intelligence for every group chat. text.ai doesn't just answer questions - it lives in your conversations, silently learns what makes each friend tick, and becomes the perfect agentic AI for YOUR specific crew. Jump in right now: Works instantly in SMS, WhatsApp, and Telegram. Zero downloads. Zero setup. Just pure ambient group genius. 🍕 "Find pizza spots we'll ALL actually like" (remembers Sarah's gluten-free, Jake's spice tolerance, everyone's budget) 🎉 "Plan something epic for Saturday" (knows the group's energy, who's free, what you actually enjoy) 🔥 "Roast my terrible movie suggestion" (adapts to your group's humor style and inside jokes) Every group chat gets its own brain. Every friend gets understood. Every plan actually works. The future isn't prompt → response. It's presence → understanding → creation. Try it now. Your friends will thank you.
