# Offline AI vs Surface Tech AI

The clearest difference is rating: Surface Tech AI at 5.0 against Offline AI's 3.8. Surface Tech AI also leads on in-app purchases (none vs 6) and update cadence (every 3 weeks vs every 2 months). Offline AI's advantage is ratings volume (9 vs 1). On price, ads and device support there is nothing between them.

Both are free to download. Offline AI sells 6 in-app purchases, starting at $4.99 per month. Surface Tech AI asks for nothing beyond the download.

Surface Tech AI holds the better App Store score, 5.0 against 3.8. That said, the two scores are not equally well evidenced: Offline AI has 9 ratings behind it against 1, so its average is the more settled of the two.

Offline AI ships an update every 2 months, Surface Tech AI every 3 weeks. The most recent releases landed on November 8, 2026 and October 30, 2026 respectively.
