DeArrow is a browser extension designed for YouTube, aiming to enhance the accuracy of video titles and thumbnails by leveraging crowdsourcing. Users can submit and vote on better titles and thumbnails, with the goal of reducing sensationalism and clickbait. The extension allows customization options where users can specify formatting preferences for titles and thumbnail display settings.

Unlike its counterpart, Clickbait Remover, DeArrow focuses on crowdsourcing improvements for titles and thumbnails. It offers sophisticated formatting options like "Title Case" and "Sentence case" when auto-generating titles, preserving the capitalization of acronyms and proper names. Additionally, DeArrow uses truly random timestamps for thumbnails to avoid biased selection, cross-checking with the SponsorBlock database to ensure thumbnails are not from sponsor segments.
