Any data format. Instantly understood.
Paste messy CSV, plain English, raw JSON, a spreadsheet dump, or outright garbage. CloviAI reads your intent, cleans the data, infers the best chart type, and renders it — automatically.
Pattern Detection
CloviAI applies regex + token classifiers to detect dates, currencies, percentages, and categorical labels — even in mixed-format inputs.
Schema Inference
After cleaning, LLM-assisted schema inference maps columns to axes, detects series dimensions, and selects the optimal chart geometry — bar, line, scatter, or heatmap.
Instant Render
The clean schema feeds directly into the chart renderer. From raw paste to finished chart image in under 200ms. One API call, one response, no preprocessing pipeline.
From statistical modeling to business dashboards
These charts were generated from real NIR spectroscopy calibration data and live outreach campaign metrics. CloviCharts handles scientific precision and business analytics with the same API.
All six charts above were generated with a single POST request per chart.
