Both are free to download. Cotomo(コトモ:音声会話型おしゃべりAI) sells 11 one-off in-app purchases and MochiChat sells 8 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
Cotomo(コトモ:音声会話型おしゃべりAI) holds the better App Store score, 4.3 against 4.0.

Written reviews complicate that: 41% of Cotomo(コトモ:音声会話型おしゃべりAI)'s written reviews are positive against 62% of MochiChat's, so the app with the better star average is not the one people write more warmly about.
Cotomo(コトモ:音声会話型おしゃべりAI) ships an update every 6 days, MochiChat weekly. The most recent releases landed on October 21, 2026 and October 19, 2026 respectively.
