# Only Markdown vs Polar AI

The clearest difference is in-app purchases: Only Markdown at none against Polar AI's 1. Only Markdown also leads on device support (3 vs 1) and iOS requirement (11.0 vs 17.0). On price and ads there is nothing between them.

Both are free to download. Polar AI sells 1 in-app purchase, starting at $9.99 per month. Only Markdown asks for nothing beyond the download.
