# KarmaBuilder vs Codex AI

The clearest difference is update cadence: Codex AI at weekly against KarmaBuilder's every 5 weeks. Codex AI also leads on ratings volume (74 vs 2). KarmaBuilder's advantage is rating (5.0 vs 4.7) and review sentiment (100% vs 80%). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. KarmaBuilder sells 3 in-app purchases, starting at $4.99 per month and Codex AI sells 12 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.
