Core Feature
Experience Navigator
Paste a job description, recruiter message, or topic. The system extracts the top semantic concepts from your input and shows you exactly how it plans to interpret your query — before generating a response. Inspect and adjust the concept priorities. Then receive a grounded response drawn exclusively from real experience.
Query Theme Decomposition
Hybrid TF-IDF + semantic scoring extracts the top 8 concepts from your input. No LLM involved in this step.
Semantic Salience Scoring
Each concept is ranked by relevance to your query. You can inspect, reorder, and reweight them before generation.
Grounded Generation
Your adjusted priorities shape which experiences are emphasised. The response cites only what is in the actual CV.
