The curly quotes converter switches your text between straight quotes and curly (smart) quotes in both directions. Turn straight quotes into polished typographer's quotes for publishing, or strip curly quotes back to straight to clean AI text and stop them breaking code, CSV, and JSON. It runs in your browser, nothing is uploaded.
Straight to curly adds typographer's quotes for polished writing. Curly to straight is the AI-cleanup direction: it strips smart quotes that break code and signal machine writing.
Curly quotes (also called smart or typographer's quotes) are the angled left and right quotation marks used in print. Straight quotes are the plain vertical ones on your keyboard. AI tools and word processors insert curly quotes automatically, which looks nice in prose but breaks code and is a machine-writing tell. This tool converts either way, curling straight quotes correctly by context, or flattening curly ones back to straight.
