Verdict on ABU

ABU AI is a bilingual Spanish/English upsell tool targeting Latin American markets. The AI-powered recommendations are a good concept, but with only 1 review it is unproven. The free plan is extremely limited at 1 order/month. Best for Spanish-speaking store owners who want native-language support.
