Verdict

The call

The clearest difference is monetization model: Zenith Agent at freemium against ChatLLM's subscription. Zenith Agent also leads on review sentiment (100% vs 64%). ChatLLM's advantage is ratings volume (3.8K vs 2) and update cadence (every 4 days vs fortnightly). On price, rating, ads and in-app purchases there is nothing between them.
