# LumenAI vs Slim AI

The clearest difference is rating: LumenAI at 5.0 against Slim AI's 3.8. LumenAI also leads on ads (none vs shown). Slim AI's advantage is ratings volume (6 vs 1). On price, review sentiment, in-app purchases and monetization model there is nothing between them.

Both are free to download. LumenAI sells 2 in-app purchases, starting at $4.99 per month and Slim AI sells 4 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.

LumenAI holds the better App Store score, 5.0 against 3.8. That said, the two scores are not equally well evidenced: Slim AI has 6 ratings behind it against 1, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.
