Text.ai

Text.ai is a San Francisco consumer AI company building Alfi, an assistant designed to operate inside group conversations rather than as a one-to-one chatbot. The company's original product was an AI that lived inside existing messaging channels — SMS, iMessage, WhatsApp and Telegram — and the team states it drew on more than 10 million messages exchanged across 150+ countries in its first few months. That usage led to a pivot toward a dedicated messaging application: Alfi, described in the company's Y Combinator launch as live on iOS and Android and available in 10+ languages.

Alfi's stated feature set includes in-chat restaurant booking with Yelp integration, collaborative ("multiplayer") image generation and editing, a shared social calendar for upcoming plans, group reminders, per-group memory of preferences and habits, a "Group Wrapped" recap of chat activity and inside jokes, customizable assistant behavior per chat, and multilingual conversation handling. A solo (one-to-one) mode is also offered alongside group chats. The company describes a proprietary framework that determines when the assistant should respond and when it should stay silent, without requiring @mentions or slash commands.

Text.ai participated in Y Combinator's Spring 2025 batch and is categorized there under artificial intelligence, consumer, social and social network. Its public site states support from Y Combinator and SV Angel. Marketing figures on the site are internally inconsistent (variously citing 500,000 people, "thousands of users," and 10M, 20M and 60M+ messages), so quantitative traction claims should be treated as unverified.

Business model

Consumer messaging product distributed as a free-to-try assistant inside group chats and, more recently, as a standalone mobile app; no pricing, subscription or monetization mechanism is disclosed in the available sources.

Traction

Self-reported figures: 10M+ messages across 150+ countries and tens of thousands of users on the original messaging-platform product; the website separately cites "trusted by over 500,000 people," "thousands of users," 20M+ and 60M+ messages exchanged, and 100,000+ images created and edited "in just weeks." These numbers conflict across placements on the same site and are not independently verified.

Latest developments

Launch of Alfi as a standalone chat app on iOS and Android in 10+ languages, with a Yelp-powered in-chat reservation feature, multiplayer image generation, a shared social calendar, Group Wrapped and per-chat customization.
