How to choose the right multilingual AI tool
Nearly half of global execs say their companies lose €8–11 million annually due to language issues (Moveworks study). Picking the ideal multilingual support AI tool is essential. Here’s what matters most:
- Translation accuracy: Poor translation can damage your brand as much as it confuses customers. Look for tools that “think” in context—like Neople, DeepL, or Helpshift’s Language AI.
- Language coverage: Plan for future growth! Insurance? 67% of customers demand native language when dealing with sensitive topics.
- Integration capabilities: Choose solutions offering native connections for your CRM, live chat, or messaging stack—especially if you’re tracking KPIs like CSAT, FCR, AHT, or ARR.
- Data protection and compliance: In the EU, GDPR isn’t a suggestion—it’s law. Also check for ISO 27001, SOC 2, or HIPAA where relevant.
- Cost-effectiveness: Smart AI can cut localization costs by 60% and reduce time to market by 80%.
- Analytics and reporting: Pick tools that measure your team’s success—look for dashboards featuring Escalation Rate, translation quality, and customer sentiment.
Pro tip: Assign weight to different criteria (accuracy, features, price) when comparing options, and use external resources like Zendesk’s localization research for benchmarks.
