Sherpa vs SketchUp Diffusion: which one when
Two AI tools that both work from SketchUp yet solve different problems. Full transparency: Sherpa is our own product, so we also tell you exactly when SketchUp's own AI Render is the better pick.
The short answer
Pick SketchUp AI Render (Diffusion) for quick style exploration inside your SketchUp AI subscription: prompt in, moods out, ideal early in the design. Pick Sherpa once the image needs to face a client: prompt-free, faithful to your own model, with controls for light, people and materials and European privacy terms. Many users combine both.

The real difference: prompts versus controls
With a prompt-driven tool you describe in text what you want to see, and the model interprets that text. That makes SketchUp AI Render strong at exploration: "Scandinavian, lots of wood, morning light" delivers a mood in seconds that you had not thought of yourself. The flip side is that the model interprets, so the result can drift from what you drew.
Sherpa turns everything that would normally go into a prompt into buttons: luminosity, time of day, colour temperature, artificial light, people, styling level and materials per surface. There is nothing to phrase and nothing to misinterpret. AEC Magazine called this approach "prompt-free AI rendering".
Exploration wants freedom, presentation wants predictability. That is the whole comparison in one sentence.
Frequently asked questions
What is the difference between Sherpa and SketchUp Diffusion?
SketchUp AI Render (formerly Diffusion) is SketchUp's built-in AI feature: you combine your model view with a text prompt, preset style or reference image, mainly for quick style exploration. Sherpa is a separate tool that turns your viewport or export into a presentation-ready client image, without prompts: light, people, styling and materials are controls.
Can I use both side by side?
Yes, and that is often the best setup. SketchUp AI Render for free-form style exploration early in the design, Sherpa once the image needs to go to a client or pitch and your design has to stay recognisable.
Do I need a SketchUp AI subscription for Sherpa?
No. Sherpa is independent of the SketchUp subscription: you use the free Sherpa Render extension from the Extension Warehouse or upload an export in the browser. A free Sherpa account includes 5 renders, no credit card.
Does my design stay recognisable with both tools?
With Sherpa that is the whole point: image-to-image on your own picture, what you drew stays put. With prompt-driven generation the result can drift further from your model, which can be exactly what you want during exploration.
What about privacy?
Sherpa never trains AI models on your images, deletes files automatically after 30 days and provides a GDPR data processing agreement on request. For SketchUp AI Render, check Trimble's terms; they vary by subscription and region.
