# Protagonist vs Grok Bot

The clearest difference is in-app purchases: Protagonist at none against Grok Bot's 3. Protagonist also leads on review sentiment (100% vs 83%) and iOS requirement (15.1 vs 18.0). Grok Bot's advantage is rating (4.9 vs 4.4) and ratings volume (13K vs 7). On price, update cadence, ads and device support there is nothing between them.

Both are free to download. Grok Bot sells 3 in-app purchases, starting at $25.99 per month. Protagonist asks for nothing beyond the download.

Grok Bot holds the better App Store score, 4.9 against 4.4. That said, the two scores are not equally well evidenced: Grok Bot has 13K ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 100% of Protagonist's written reviews are positive against 83% of Grok Bot's, so the app with the better star average is not the one people write more warmly about.

Protagonist ships an update every 5 days, Grok Bot every 4 days. The most recent releases landed on October 11, 2026 and October 20, 2026 respectively.
