Verdict
The clearest difference is rating: Vanish at 4.7 against Kagi Assistant's 4.5. Vanish also leads on ratings volume (201 vs 45) and iOS requirement (15.1 vs 18.0). On price, review sentiment, update cadence and ads 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. Vanish sells 3 in-app purchases, starting at $5.99 per 7 days and Kagi Assistant sells 1 in-app purchase, starting at $28.99 per month. Whichever you choose, the download price is not the number that matters.
Vanish holds the better App Store score, 4.7 against 4.5. Both are backed by a comparable volume of ratings — 201 and 45 respectively. Written reviews complicate that: 50% of Vanish's written reviews are positive against 56% of Kagi Assistant's, so the app with the better star average is not the one people write more warmly about.
Vanish ships an update weekly, Kagi Assistant every 10 days. The most recent releases landed on November 5, 2026 and November 9, 2026 respectively.
