# Gauth vs Question.AI

Gauth and Question.AI both sit at 4.8 stars, but that hides the real split: 77% of Gauth's written reviews are positive against 61% of Question.AI's. Gauth also leads on ratings volume (1.5M vs 164K) and chart position (#12 vs #47). On price, rating, update cadence and ads there is nothing between them.

Both are free to download. Gauth sells 10 in-app purchases, starting at $11.99 per month and Question.AI sells 7 in-app purchases, starting at $6.99 per 7 days. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.8 for Gauth against 4.7 for Question.AI. That said, the two scores are not equally well evidenced: Gauth has 1.5M ratings behind it against 164K, so its average is the more settled of the two. Written reviews are what separate them: 77% of Gauth's written reviews are positive against 61% of Question.AI's.

Gauth ships an update every 2 weeks, Question.AI fortnightly. Both last shipped on November 8, 2026.
