Hello everyone,

Bringing lightweight, interactive 3D AI characters to web browsers without heavy game engine builds is now easier than ever! We are excited to release a brand-new tutorial showing you how to build browser-based AI avatars using the Convai Web SDK, Claude Code, Vite, TypeScript, and React Three Fiber (R3F).

In this tutorial, we show how you can leverage AI coding agents like Claude Code to accelerate project scaffolding directly from the Convai Web SDK documentation, render custom 3D GLB avatars in the browser, and hook up real-time lip sync via blendshapes.

:sparkles: What We Cover in This Tutorial

  • :globe_with_meridians: Project Setup with Claude Code: Use Claude Code to quickly generate your web project setup using Vite, React Three Fiber, and TypeScript from the Convai Web SDK docs.

  • :robot: Convai Web SDK Integration: Connect your character using your API key and Character ID, render the 3D avatar, and add the interactive Convai widget.

  • :speaking_head: Real-Time Voice Interaction: Enable fluid, low-latency voice conversations directly inside the browser.

  • :mouth: Custom GLB Avatars & Lip Sync: Bring your own .glb 3D avatar into R3F, inspect blendshapes with a GLTF viewer, and drive precise lip sync using blendshape data provided by the Convai Web SDK.

This workflow is ideal for developers building web-based AI companions, virtual tour guides, interactive real estate walkthroughs, lightweight 3D web applications, and conversational web avatars.
