Verdict
The clearest difference is review sentiment: AI Writer at 54% against AI Chat Assistant's 0%. AI Writer also leads on rating (4.3 vs 3.0) and update cadence (every 8 days vs every 10 months). 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 Chat Assistant sells 3 in-app purchases, starting at $4.99 per 7 days and AI Writer sells 3 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.
AI Writer holds the better App Store score, 4.3 against 3.0. That said, the two scores are not equally well evidenced: AI Writer has 125 ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 0% of AI Chat Assistant's written reviews are positive against 54% of AI Writer's.
AI Chat Assistant ships an update every 10 months, AI Writer every 8 days. The most recent releases landed on November 3, 2026 and November 7, 2026 respectively.
