CEFRhub vs Hallo AI — Comparison (2026)
Hallo AI and CEFRhub both use artificial intelligence for language learning purposes, but they serve very different goals. Hallo AI is a conversational practice app focused on speaking fluency, while CEFRhub is a formal CEFR assessment tool that analyses your language productions.
This comparison clarifies what each tool does, so you can choose the right one — or use both.
What Each Tool Is Designed For
Hallo AI
Hallo AI is an AI-powered conversation practice app designed to help users improve their English speaking skills. Users engage in spoken dialogues with an AI tutor on various topics. The focus is on building fluency, confidence, and pronunciation through repeated practice. Hallo AI provides real-time feedback on pronunciation and suggests corrections during conversation.
Hallo AI is a practice tool, not a formal assessment platform. It does not produce CEFR-mapped reports or evaluate written language. Its strength lies in providing low-pressure, accessible speaking practice.
CEFRhub
CEFRhub is an AI-powered language assessment platform that analyses written and oral productions against 1,800+ official CEFR 2020 descriptors. Users submit text or audio samples, and the AI produces a detailed competency report with sub-level precision. CEFRhub is designed for assessment — knowing where you stand — rather than practice.

Why Choose CEFRhub
- Formal CEFR assessment: CEFRhub maps your performance to CEFR levels with sub-level precision and references to specific descriptors. This gives you a standardised, comparable measure of your language level.
- Written and oral evaluation: CEFRhub assesses both written and spoken productions, while Hallo AI focuses exclusively on spoken conversation.
- Detailed competency reports: Each assessment produces a breakdown of linguistic range, grammatical accuracy, pragmatic competence, and phonological control — useful for identifying specific areas to improve.
- Organisational use: CEFRhub supports team management, batch assessments, and exportable PDF reports for recruitment, education, and training contexts.
- Recruitment without testing: Evaluate a candidate's real language level from their existing work samples — emails, reports, presentations — without scheduling a separate test.
Why Hallo AI Has Strengths
- Unlimited speaking practice: Hallo AI provides a low-pressure environment to practise speaking as much as you want. CEFRhub is an assessment tool, not a practice partner — it evaluates what you produce but does not engage in conversation.
- Real-time conversational feedback: Hallo AI corrects pronunciation and grammar during the conversation itself, which helps build fluency through immediate reinforcement.
- Accessible and engaging: The conversational format makes Hallo AI approachable for learners who may find formal assessment intimidating. It is designed for daily, casual use.
The Complementary Approach
Testing tells you how someone performs on an exam. Evaluation tells you how someone performs in real life. Hallo AI tests. CEFRhub evaluates.
The most effective language development strategy combines both: use Hallo AI for daily speaking practice to build fluency, then use CEFRhub to formally measure your progress with a detailed CEFR report. Practice, then measure. Repeat.
Is Hallo AI a CEFR assessment tool?
No. Hallo AI is a practice app, not a formal assessment platform. It does not produce CEFR-mapped reports or scores. If you need to know your CEFR level with documentation, CEFRhub is designed for that purpose.
Can I use both Hallo AI and CEFRhub?
Yes, and this is a strong combination. Use Hallo AI for daily speaking practice to build fluency, then use CEFRhub periodically to formally assess your progress and identify specific competency gaps.
Does CEFRhub offer conversation practice?
No. CEFRhub analyses language samples you submit — it does not engage in interactive conversation. For practice, a tool like Hallo AI or a language tutor is more appropriate.
Does Hallo AI assess writing?
No. Hallo AI is speaking-only. CEFRhub can assess both written text and oral recordings.
Which tool is better for a language school?
CEFRhub is better suited for institutional use. It provides formal assessment reports, supports organisation accounts with member management, and produces exportable documentation. Hallo AI is designed for individual practice.
