An Open Source AI addon that won't do your work, but can teach you how.

Designed Around the Way You Learn

Learn Blender while working on your own projects.

Ever get stuck in Blender and wish someone could just show you what to do next?

That's why I built BlenderMentor. It's an AI-powered learning companion that understands the scene you're working on, guides you to the right tools and settings, and explains why each step matters. You stay in control, do the work yourself, and learn something along the way.

VISUAL GUIDANCE

In-Viewport Highlighting Shows You Where to Look

Blender's interface can be overwhelming with hundreds of buttons, tabs, and nested panels. Instead of leaving you to search through menus, BlenderMentor visually highlights the exact modifier, tool, or setting directly inside Blender. Matching icons appear in your guide so your eyes immediately find what you need.

SCENE AWARENESS

Reads Your Scene Directly.

Explaining a Blender scene to an AI in chat can be exhausting. BlenderMentor inspects your scene state automatically; active modifiers, object vs. edit mode, transforms, unapplied scales, materials, and viewport shading. You just ask your question, and it diagnoses your actual scene without you having to write paragraphs describing what is on your screen.

BlenderMentor intentionally does NOT look at your screen. This saves a lot on token usage and makes it relatively faster.

VOICE INPUT

Ask by Voice, While You Work.

Press [Alt + ↑] to summon Voice Input right from your keyboard. Ask questions, receive step-by-step instructions, press [Alt + ←] or [Alt + →] to move through steps and continue without breaking your flow.

LEARNING RATIONALE

Clear Steps That Explain Why Each Action Matters

Following instructions is one thing. Understanding what's happening is what helps you get better at Blender.

BlenderMentor explains the reasoning behind each step, too. And if a step doesn't quite make sense, tap Ask ? to ask a followup question in context. There's no need to feel stuck or pretend you've understood something you haven't.

WORKSPACE COMFORT

Keep Your 3D Viewport Clean with the Companion View

Your 3D viewport is where the magic happens. It shouldn't have to compete with a wall of instructions.

BlenderMentor lets you open the full interactive guide in a separate browser window on a second monitor. Your Blender workspace remains clutter-free, and dedicated to your scene.

BUILT AFTER WORK.
BUILT IN THE OPEN.

BlenderMentor is a personal project, currently being built by one person vibe coding this after work on Weekends. I'm building it because I wanted a better way to learn Blender, and I'd love to make it useful for others, too.

If you're a developer who enjoys tinkering, a writer who loves explaining things, or a 3D artist willing to give the add-on a try and tell me what broke, you're welcome here.

Try it, explore the code, share your ideas, or help make it better. BlenderMentor is fully open source under GPL-3.0, and every bit of feedback helps. Let's build something useful together.

IMPORTANT NOTE

BlenderMentor is an independent open-source hobby project. It is strictly unofficial and is in no way affiliated with, sponsored by, or endorsed by the Blender Foundation or Blender Institute.

The Story Behind BlenderMentor

Why I built this

I built BlenderMentor because I wanted a little help while working on my own Blender projects.

Whenever I got stuck, I'd turn to a general-purpose AI chat tool. But explaining a Blender problem wasn't always easy. I'd have to describe the object I had selected, the modifiers I was using, whether I was in Object or Edit Mode, whether my scale was applied, and sometimes even what my mesh looked like. The back and forth was tiring.

I wanted something that understood the context of my work, so I could spend less time explaining the problem and more time solving it.

I want AI to teach, not take over. Modern AI tools often try to generate 3D models for you, but if software does the work, you never learn Blender. You do not build intuition or muscle memory. I wanted a patient mentor to guide my hands, not replace them.

I also avoided heavy computer vision systems that continuously capture the screen. They burn massive tokens, and risk privacy. Instead, BlenderMentor connects directly to Blender's Python API. It only inspects relevant scene data, and uses minimal tokens.
