Collectively, these tweaks made BibiGPT more customizable—and more useful for people juggling different media sources.

ChayaCha Mini-Program: AI Apps Inside WeChat

ChayaCha is an “AI quick app platform” designed for the WeChat ecosystem. The vision: let anyone build and share their own AI apps within minutes.

Highlights:

  1. Template marketplace spanning scenarios like “reply to boss,” “write Xiaohongshu captions,” “name generator,” “weekly report ideas,” and more.
  2. Worker’s toolkit – everyday prompts for softening a “no,” writing polite responses, or brainstorming ideas.
  3. One-click creation and sharing – customize a template (or start from scratch) and share it across WeChat.
  4. Zero-code workflow – no technical background required.

The overarching goal was to lower the barrier to AI adoption in daily life.

OpenGPT: Web-Based AI App Builder

OpenGPT mirrored ChayaCha on the web. Its mission: “Create ChatGPT applications in seconds.”

Core capabilities:

  1. Community app library – explore apps published by other creators.
  2. Quick creation flow – supply a name, description, prompt, and sample input to spin up your own app.
  3. Custom icons – assign emojis for at-a-glance differentiation.
  4. Immediate testing – preview responses before publishing.
  5. Easy sharing – distribute your app with a single link.

Creating an AI app on OpenGPT

Together, ChayaCha and OpenGPT represented our first steps toward an AI app ecosystem.

Mofa.si: A Community for AI Magic

The video also introduced Mofa.si, a community space for learning “AI spells.” Our broader vision: combine BibiGPT, ChayaCha, OpenGPT, and Mofa.si into an ecosystem where everyone can learn, build, and apply AI in their day-to-day work and life.

Looking Back

The “Build AI Apps in One Click” update marked a shift from standalone tool to platform mindset. ChayaCha and OpenGPT were experiments in democratizing AI creation—while the interfaces have changed, the mission remains the same: make AI accessible to everyone.
