FAQ
Student recordings are transcribed using Whisper AI, then scored against the official IELTS criteria by Claude AI. Each session receives four sub-scores (Fluency, Lexical Resource, Grammatical Range, Pronunciation) and an overall band estimate.
MP3, WAV, M4A, and OGG for audio. TXT for pre-written transcripts. DOCX and PDF for written responses. Maximum file size: 50MB per recording.
Audio files are deleted immediately after transcription. Transcripts and scores are stored securely. We never share or sell student data. Your data is processed across trusted AI providers (Anthropic, Whisper) under strict data processing agreements.
