# Writing & Paraphrase vs 聊书AI

The clearest difference is update cadence: 聊书AI at every 4 days against Writing & Paraphrase's fortnightly. 聊书AI also leads on iOS requirement (13.0 vs 15.5). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Writing & Paraphrase sells 2 in-app purchases, starting at $4.99 per 7 days and 聊书AI sells 3 in-app purchases, starting at $6.99 per month. Whichever you choose, the download price is not the number that matters.

Writing & Paraphrase ships an update fortnightly, 聊书AI every 4 days. The most recent releases landed on November 4, 2026 and October 25, 2026 respectively.
