Download Chat Companion v1.5.2 for Blender on Windows and Mac, a revolutionary addon that integrates advanced Large Language Model (LLM) capabilities directly into your 3D viewport. With context-aware scene analysis, instant Python script generation, and intelligent troubleshooting, Chat Companion transforms how you solve problems and automate tasks, eliminating the need to switch between Blender, documentation, and external AI chatbots.

Key Features of Chat Companion v1.5.2:

Context-Aware Scene Analysis: The AI “sees” your current selection, active object, and modifier stack, allowing it to give specific advice like “Your normal map is flipped because the scale is negative” or “Try adding a Subdivision Surface modifier here.”

Instant Python Script Generation: Describe a tool you need in plain English (e.g., “Create a script to randomize vertex colors on selected faces”), and the addon generates, explains, and executes the code instantly within Blender.

Smart Error Troubleshooting: Paste an error log from the console, and Chat Companion analyzes the stack trace to provide a clear, step-by-step solution tailored to your specific Blender version and setup.

Interactive Learning & Documentation: Ask questions like “How do I rig a mechanical arm?” or “Explain Geometry Nodes instance on points,” and receive concise, illustrated tutorials without leaving the software.

Custom Prompt Library: Save and organize your most useful AI prompts (e.g., “Optimize for VRChat,” “Cleanup UVs,” “Batch Rename”) for one-click access during repetitive workflows.

Multi-Model Support: Connect to various LLM backends including local models (via Ollama/LM Studio for privacy) or cloud APIs (OpenAI, Anthropic), giving you full control over cost and data security.

Voice Command Integration (Beta): Speak your commands to generate scripts or ask questions hands-free, perfect for when your hands are busy sculpting or painting.

Enhanced Privacy v1.5.2: New “Local-First” mode ensures sensitive project data never leaves your machine when using local models, along with improved token management to reduce API costs.

Cross-Platform Support: Works flawlessly on both Windows and Mac systems including Apple Silicon M1/M2/M3 chips

Technical artists needing quick custom tools without deep Python knowledge

Beginners struggling with Blender’s steep learning curve and complex menus
