Verdict

The call

The clearest difference is monetization model: AI Sonic at freemium against EssAI Pro's subscription. AI Sonic also leads on ratings volume (725 vs 1) and iOS requirement (13.0 vs 15.0). EssAI Pro's advantage is update cadence (monthly vs every 7 months) and rating (5.0 vs 4.7). On price, ads, in-app purchases and device support there is nothing between them.
