About AirCaps
Summary
AirCaps builds smart glasses that display real-time captions, translations across 60-plus languages, and AI-generated meeting notes directly in the wearer's field of view during face-to-face conversations. The product serves deaf and hard-of-hearing users, international travelers, and professionals such as sales reps, doctors, and lawyers. It replaces manual note-taking, human interpreters, and the post-meeting summarization tools that only work after a conversation ends.

The AI copilot for in-person conversations.
AirCaps is bringing AI assistance to in-person conversations. Our AI-copilot provides live captions, translations, AI meeting notes and insights for in-person conversations in real-time. It's deployed as an app for lightweight AR glasses so you can see visual information overlaid onto your field of vision. You can think of it like a Zoom AI meeting assistant or Granola, but for in-person conversations, and with the ability to proactively help you in real-time, not just after the conversation. We’re building the capture and intelligence layer for the 216 billion daily conversations that happen face-to-face. We’ve already processed 16,500 hours of real-world conversations and counting. Today, AirCaps assists with 11% of our users’ in-person conversations. We did $93K in revenue in October and grew 6.5x from September while spending <$3K on marketing (and hit $70K in revenue in the first 2 weeks of November). Our power users average 6h+ daily usage and our day-30 retention is 91%. We previously went viral (75M+ views on TikTok, 150K+ followers) and have been featured by The New Yorker, WIRED, and Forbes. Madhav (CEO, Yale CS) has been building in audio and AR since age 13, starting with Google Glass apps and voice assistants for Raspberry Pis. He researched audio AI at the MIT Media Lab. Nirbhay (CTO, Cornell CS) built voice AI on smart glasses in high school and built conversational AI products as the first engineer at 2 YC startups.
