ChartLint

ChartLint is a web app (with a lightweight Figma/Google Slides add-on) that audits charts and infographics for clarity, accessibility, and statistical integrity. Users upload an image/PDF or paste a link, and the app flags common information-design failures: truncated axes, inconsistent scales, color contrast issues, illegible labels, missing units, misleading dual axes, cherry-picked ranges, and chart-type mismatches. It outputs a prioritized checklist with fixes, plus auto-generated alternative chart suggestions and an accessibility report (WCAG contrast, color-blind safe palette, font sizing). It’s an AI app combined with traditional rules: deterministic heuristics catch the obvious issues, while a vision-language model explains why something is misleading and proposes better encodings. It also generates a “design rationale” snippet teams can paste into PRDs or review comments. Realistically, it won’t replace a skilled designer, but it can prevent embarrassing mistakes and speed up review cycles.
