Our verdict

Highlight GPT explains any selected passage using the surrounding context, translates across multiple languages for non-native speakers, and lets users choose between simple definitions and more detailed analysis. Students, researchers and professionals working through dense or foreign-language material get quick clarification without switching tools. It only explains text, not images, audio or other media on the page, and explanations sometimes lack the nuance needed to avoid occasional misunderstandings.
