Automated rigging is crucial for modern 3D workflows. Our definitive guide to the best AI rigging tools and 3D model converters of 2026. We've collaborated with professional 3D artists and developers to test leading platforms for preparing 3D assets for animation.
From understanding how AI is revolutionizing character setup with one-click rigging to seeing how integrated converters streamline asset pipelines, these platforms stand out for their innovation and power in the 3D animation process.
What Is an AI Rigging Tool & 3D Model Converter?
An AI rigging tool is a specialized piece of software that uses artificial intelligence to automatically create a digital skeleton (a 'rig') for a 3D model, making it ready for animation. This process, traditionally manual and time-consuming, is drastically sped up by AI. An integrated 3D model converter then allows users to export these rigged models into various formats (like FBX, GLB, or OBJ) suitable for different game engines, animation software, and virtual reality platforms.

Animate Anything
The Good
- Simplifies the entire rigging and animation process into a few clicks
- Compatible with various common 3D formats (FBX, GLB, GLTF)
- Offers a free version for students and personal projects
The Bad
- Optimized for lower-detail characters, not ideal for high-end models
- Automatically decimates models over 20,000 vertices, which can reduce detail
Animate Anything is an AI animation tool that automatically rigs and animates 3D models, supporting multiple formats like FBX, GLB, and GLTF.
2026 Analysis
Animate Anything is a highly accessible tool, perfect for beginners, students, or developers working on projects with less demanding graphical requirements, such as web-based AR. Its free tier makes it an excellent entry point into AI animation. The main drawback is its handling of high-poly models, which are automatically simplified, making it unsuitable for cinematic or high-fidelity game asset creation.
