About
Hallo is an enterprise-grade AI language assessment platform that automates the evaluation of language proficiency across speaking, writing, reading, and listening skills in more than 60 languages. Built for global organizations, it replaces slow, costly manual language screening with fast, affordable, and accurate AI-driven assessments. Candidates complete five scenario-based, open-response questions on any device, and immediately receive detailed CEFR score reports covering fluency, vocabulary, grammar, pronunciation, coherence, and more. Pronunciation analysis evaluates clarity, intonation, stress, and rhythm for granular accent and speech feedback. Hallo integrates seamlessly into existing HR stacks via API and ATS integrations, enabling teams to invite candidates, manage score reports, and download results in real time. Built-in proctoring and cheating-prevention protocols ensure assessment integrity, while monthly third-party AI audits address bias, fairness, and compliance. Beyond assessment, Hallo also offers an AI Language Tutor for conversational practice and lessons across 50+ languages, making it a comprehensive solution for both talent evaluation and employee learning and development. The platform is certified SOC II Type 2, ISO 27001, GDPR-compliant, and aligned with the EU AI Act, making it a secure and ethical choice for enterprise deployments. Hallo is ideal for HR professionals conducting pre-employment screening, BPO and customer service organizations validating agent language skills, consultancies doing placement testing, and L&D teams building multilingual workforces.
