About future feature expansions

As we ship new modules, the free plan's daily ad count may be adjusted dynamically by our team. Annual and Lifetime subscribers are unaffected — always ad-free, no matter how many features we add.

All three plans unlock the same features. The difference is only ads and how you pay. All AI runs locally.
