# Meta AI vs SIGMA

The clearest difference is ads: SIGMA at none against Meta AI's shown. SIGMA also leads on iOS requirement (13.0 vs 18.4). Meta AI's advantage is update cadence (every 6 days vs monthly) and chart position (#10 vs unranked). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Meta AI ships an update every 6 days, SIGMA monthly. The most recent releases landed on November 1, 2026 and October 28, 2026 respectively.
