# DupScore vs Grok AI

The clearest difference is update cadence: Grok AI at every 2 days against DupScore's fortnightly. Grok AI also leads on ratings volume (1.5M vs 24) and chart position (#4 vs unranked). DupScore's advantage is review sentiment (87% vs 71%). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. DupScore sells 3 in-app purchases, starting at $7.99 per month and Grok AI sells 12 in-app purchases, starting at $10.00 per month. 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 DupScore against 4.9 for Grok AI. That said, the two scores are not equally well evidenced: Grok AI has 1.5M ratings behind it against 24, so its average is the more settled of the two. Written reviews are what separate them: 87% of DupScore's written reviews are positive against 71% of Grok AI's.

DupScore ships an update fortnightly, Grok AI every 2 days. The most recent releases landed on September 15, 2026 and October 1, 2026 respectively.
