LLM-structured news metadata with sentiment labels, history to 2000
Zanista AI's NewsWitch product applies large language models to around one million news articles a day, converting them into structured, sentiment-tagged metadata with history from 2000. Traders, hedge funds and quantitative researchers access it via API or dashboards; the London company also sells AI exam-grading tools.
