# Deep ChatAI vs AI Assistant

Deep ChatAI and AI Assistant both sit at 4.2 stars, but that hides the real split: 100% of AI Assistant's written reviews are positive against 0% of Deep ChatAI's. AI Assistant also leads on monetization model (free with in-app purchases vs subscription) and update cadence (every 3 days vs every 3 weeks). Deep ChatAI's advantage is ads (none vs shown) and ratings volume (38 vs 4). On price, rating, in-app purchases and device support there is nothing between them.

Both are free to download. Deep ChatAI sells 3 in-app purchases, starting at $3.99 per 7 days and AI Assistant sells 6 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Deep ChatAI holds the better App Store score, 4.2 against 4.0. That said, the two scores are not equally well evidenced: Deep ChatAI has 38 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 0% of Deep ChatAI's written reviews are positive against 100% of AI Assistant's, so the app with the better star average is not the one people write more warmly about.

Deep ChatAI ships an update every 3 weeks, AI Assistant every 3 days. Both last shipped on October 24, 2026.
