# CastOn vs ChatIt AI Assistant

The clearest difference is review sentiment: ChatIt AI Assistant at 87% against CastOn's 36%. ChatIt AI Assistant also leads on rating (4.9 vs 4.5) and update cadence (weekly vs every 4 weeks). CastOn's advantage is ratings volume (5.5K vs 246). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. CastOn sells 11 in-app purchases, starting at $4.99 per 7 days and ChatIt AI Assistant sells 12 in-app purchases, starting at $5.99 per 7 days. Whichever you choose, the download price is not the number that matters.
