The most generous free tier in spreadsheet AI
Many competing AI add-ons require paid subscriptions or impose tight monthly limits. LunaRabbit Office offers a generous free tier with monthly AI credits, no credit card, no watermarks, and all 17 custom AI functions unlocked from day one. Returning users get even more value: repeated tasks are cached free for 30 days.

Pricing Questions

Yes. The Free plan includes monthly AI credits at no cost, with access to all 17 AI custom functions and the Sprinter AI mode. No credit card required, no watermarks, no hidden fees. Advanced AI modes (Solver, Operator, Commander) will be available with paid plans when they launch.

Paid plans are coming soon. We are finalizing our billing integration to ensure a secure, smooth checkout experience. Click "Get Notified" on any paid plan above to be the first to hear when it launches. Early adopters will get preferential pricing.

Your credits reset on the first day of each month. You can wait for the reset, or upgrade to a paid plan for a larger monthly allowance once paid plans launch. Previously completed tasks with the same inputs stay cached for 30 days and run free — so you keep getting value even with a smaller allowance.

The plans differ in two ways: (1) which AI modes are unlocked — Free gives you Sprinter, Lite adds Solver & Operator, Basic adds Commander, and Pro/Max keep all modes with larger credit pools; (2) how much monthly AI work you can do. Higher-tier modes produce higher-quality results but also consume credits faster — your selection interface shows clear usage hints for each mode.

No. Monthly credits reset on the first day of each month and do not roll over. However, results from completed AI tasks are cached for 30 days — so if you repeat the same task within that window, it runs free of charge.

Once paid plans launch, consumers in the EEA and the UK have a 14-day cooling-off period, consumers in South Korea have a 7-day cooling-off period for unused credits, and customers in the United States and other regions are eligible for a 14-day goodwill refund window. Already-consumed credits are not refundable. See our Refund Policy for full details and request instructions.
