To buy more AI credits in SketchUp, you don’t purchase credits one‑by‑one—instead, you add an AI subscription (add‑on) to your account.
- Open SketchUp AI (AI Render or AI Assistant).
- Click Credits in the interface.
- Click Increase Balance.
- This opens Trimble’s checkout page in your browser.
- Complete the purchase.
👉 This flow is described here: SketchUp AI Subscription [help.sketchup.com]
Important things to know
1) You’re buying a subscription, not individual credits
- The add‑on gives you +1500 AI credits per month [help.sketchup.com], [help.sketchup.com]
- It auto‑renews monthly until you cancel [help.sketchup.com]
2) You already get some credits with your plan
Your base SketchUp subscription includes monthly credits:
- Go → 100 credits/month
- Pro → 150 credits/month
- Studio → 200 credits/month [help.sketchup.com]
3) Credits reset monthly
- Your balance resets every billing cycle
- Unused credits don’t roll over [help.sketchup.com]
4) You can only buy it inside SketchUp
- The AI add‑on cannot be purchased separately on a website
- You must use the in‑app “Increase Balance” button [help.sketchup.com]
⚙️ Quick example
If you’re using AI Render or Generate Object heavily:
- Run out of credits → SketchUp prompts you to upgrade
or - Pre‑emptively go to Credits → Increase Balance
👍 Pro tip (to save credits)
- AI Render typically costs ~10 credits per generation
- Generate Object costs ~30 credits per object [help.sketchup.com]
So refining your prompts before hitting “Generate” can stretch your credits further.
