Desktop AI, explained
Pay for the app once.
Use AI your way.
“Bring your own API key” means you connect an AI account you control. The key is a private access code that lets LUC send requests to your chosen provider. No coding needed.
The US$69.99 app price does not include AI usage. Your provider charges you directly for the requests you make. LUC adds no AI usage charge.
Paste it once.
In Desktop, open Settings → AI Provider. Paste and save your key. A supported model is already selected. Your key stays protected on that computer.
Try one sample.
Start with a made-up example, then review the result. AI needs internet, and even a connection test may incur a small provider charge.
AI is optional. Keep entering marks, taking attendance and grading manually without a key or provider bill. A ChatGPT or other chat subscription can have separate API billing. Provider budget alerts are not always hard spending caps. Read the full setup guide.
Your Desktop purchase
From checkout to your classroom.
Buy & save your licence.
Pay securely through Stripe. On the confirmation page, save your licence and private recovery file for later access.
Choose your Mac download.
Pick Apple silicon or Intel, then the installed or portable edition. Internet is needed to activate each computer, up to three at a time.
Teach offline. Connect as needed.
Manual tools keep working offline indefinitely after activation. Google Classroom, optional AI and updates need internet. Future Desktop updates are included.
A few differences that matter.
| Your choice | Online | Offline Desktop |
|---|---|---|
| Where records live | In LUC’s hosted service, accessed through your account. | In your local workspace. You manage backups and move data between computers; there is no automatic cloud sync. |
| AI billing | LUC plan credits and plan limits. | Optional provider account, your own key and separate usage bill. |
| Student access | Student and parent portals and connected classroom features. | Teacher tools. Print or export reports and leaderboards; no LUC student or parent portal. |
| Google Classroom | Available on supported Online plans. | Optional internet connection: link a course, sync LUC-created assignments and reviewed grades, and select submitted files for local review. |
| Portable use | Open the Online app in a supported browser. | Portable Mac edition included. School rules may still prevent running apps from a USB drive. |
Full app refund when requested within 14 days.
Separate AI-provider charges are not refunded by LUC.
