Verdict
The clearest difference is ratings volume: OpenCat at 852 against AIトーク Chat Bot's 25. OpenCat also leads on rating (4.6 vs 4.4). AIトーク Chat Bot's advantage is update cadence (every 2 days vs weekly) and iOS requirement (15.0 vs 17.0). On price, ads, in-app purchases and monetization model there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. AIトーク Chat Bot sells 5 in-app purchases, starting at $1.99 per 7 days and OpenCat sells 4 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.
OpenCat holds the better App Store score, 4.6 against 4.4. That said, the two scores are not equally well evidenced: OpenCat has 852 ratings behind it against 25, so its average is the more settled of the two.
AIトーク Chat Bot ships an update every 2 days, OpenCat weekly. The most recent releases landed on October 30, 2026 and November 3, 2026 respectively.
