About DeArrow

DeArrow is a browser extension that replaces titles and thumbnails on YouTube with versions submitted by the community. Its stated goal is to make titles more accurate and reduce sensationalism. Thumbnails are screenshots taken from specific timestamps in a video, and users submit and vote on both titles and thumbnails.

When a video has no submissions, DeArrow formats the original title to a user-specified format and sets a screenshot from a random timestamp as the thumbnail. Users can change these defaults in the options, including turning off title formatting or showing the original thumbnail by default. The project is available as a browser extension, on iOS, and on the web, and it provides a public API with documentation.
