AI Festa 2026: The Day We First Showed Croche to the World

Our Journey is a short, photo-led series about the places the H1R.ai team has been.

In October 2026 we opened the String booth at AI Festa 2026 and showed Croche in public for the first time. Across the booth wall we put one line: "From imagination to launch, one click with Croche." We wanted to say it simply: app makers focus on their app, and Croche takes care of the AI inside it.

Visitors could try apps built with Croche on the spot: character chat, an interactive AI game, an AI tutor. Many stopped at the same point: the cost, quality and security problems that grow as conversations get longer can be handled by a single Croche SDK, at about 10 won for 50 long conversations.

Over three days we met a great many developers, students and companies. Those conversations led to a PoC with a US AI healthcare company, design partners, and talks on IP content and enterprise AX collaborations. It was also where we first announced the AI app hackathon with Seoul National University.

It was Croche's first stage outside the lab, and the questions and feedback we heard that day shaped the Croche of today.
