Data analysis that reads your Excel or CSV, produces an interactive HTML report in one of 5 editorial styles, and exports to a HTML deck on request. Three-layer protocol: WHAT the data shows, WHY it's happening, and SO WHAT to act on — output as interactive HTML report (5 editorial styles). Unlike tools that stop at charts, this verifies assumptions before analyzing, explains causes, and produces recommendations with mechanism, evidence, and estimated impact.
Markets do not move for one clean reason. Name any stock, index, sector, crypto asset, or macro market, and get a structured force-field report that shows the bearish and bullish drivers, their intensity, their time horizon, and the causal chain behind the move. The output is a self-contained HTML report with vector cards, net pressure by weekly/monthly/quarterly/annual horizon, key inflection points, and three scenarios. Open it in a browser or print it to PDF.
Paste AI-drafted text and get a genre-aware rewrite that lowers detection risk while keeping your voice. Students worry essays get flagged, creators worry articles sound templated, SEO pros worry rankings, marketers worry copy reads robotic — this fixes it. First pass uses general rules; share your detector's score and AI/human markings for precise reduction — it learns that detector's pattern and adapts each round. Five intensity levels; citations and technical terms protected.
