# LingXi vs Viki AI

Both are free to download. LingXi sells 7 one-off in-app purchases and Viki AI sells 15 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

LingXi ships an update every 4 days, Viki AI fortnightly. The most recent releases landed on November 12, 2026 and October 30, 2026 respectively.
