IELTS Prep (BandReady) is an offline-first Electron + Python sidecar application that provides full IELTS exam simulation across Speaking, Writing, Reading, and Listening, using local or user-chosen cloud AI models for scoring and live voice interaction. It includes a rich content bank, FSRS vocabulary review, pronunciation drills, and a privacy-preserving architecture with loopback-only server and encrypted keys. The project is a substantial integration of WebRTC, TTS, and LLM scoring, though it remains tied to a specific exam niche.

Target audience: IELTS test takers and language learners seeking offline, self-hosted exam practice; also useful for educators and developers interested in AI-assisted assessment.
