# Go vs Go AI

The clearest difference is in-app purchases: Go at none against Go AI's 1. Go AI's advantage is update cadence (every 4 days vs monthly). On price, review sentiment, ads and device support there is nothing between them.

Go ships an update monthly, Go AI every 4 days. The most recent releases landed on October 30, 2026 and October 31, 2026 respectively.
