System Capabilities
Multilingual RAG
Cohere embed-multilingual-v3 — retrieval at embedding level, not via translation. EN / MS / ZH.
Neural Reranking
Cohere rerank-multilingual-v3 cross-encoder re-scores top-k chunks before generation.
Multi-Query Augmentation
Question expanded to ×4 language variants before retrieval to improve cross-lingual recall.
Evidence Guard (anti-hallucination)
Refuses to generate when retrieved evidence is below the confidence threshold.
Faithfulness Scoring
Per-answer grounding score (Cohere reranker: answer vs source chunks). Shown in chat UI.
Section-Aware Chunking
360-word chunks with 45-word overlap; detects section headers to preserve document structure.
Voice I/O
Groq Whisper STT for voice input. ElevenLabs TTS + browser speechSynthesis fallback for audio output.
Multi-Turn Context
Last 3 Q&A turns passed as context so follow-up questions (e.g. 'tell me more') work correctly.
Suggested Follow-ups
After each answer, 3 contextual follow-up questions are suggested and clickable.
PDF Viewer + Citation Linking
Click any source pill → highlights the passage in the in-app PDF panel.
Evaluation Dashboard

Body font designed for low-vision users. Voice I/O for audio-first access.
Offline Fallback Cache
Prior Q&A excerpts cached in localStorage; auto-triggers when network is unavailable.
