Digiplot – automatically extract data from chart images with AI

Digiplot is a web-based tool from a small startup (apparently called "Korki" and released in late 2024) that uses computer vision and AI to extract underlying numeric data from static chart images (PNG, JPG, etc.). Users upload a screenshot of a bar chart, line graph, scatter plot, or radar chart, and the system returns the raw data in tabular form. This solves a common pain point: many papers, reports, and dashboards present data only as images with no downloadable table, making it impossible to copy-paste numbers or re-analyze them. The tool offers tiered pricing (free tier capped at 5 extractions/month, then $12–$99/month for higher volumes) and also has an API for automated pipelines. It competes with services like ChartPixel and PlotDigitizer (open-source, desktop-based). The key limitation is accuracy: chart axes can be ambiguous, and busy or low-resolution images often lead to misread values.
