SlideBySide is a browser-based presentation tool designed for people to present and follow a deck together without screen sharing or installing meeting software. A presenter uploads a PDF or PowerPoint file, or imports a deck from Google Drive, Google Slides, or OneDrive, then shares a link. People who open it join without signing up and see the same slide as the presenter. The service is free to start, and users can create an account later to keep their slides.
The presenter can advance slides for everyone, while viewers can also browse independently and return to the live presentation. Participants’ cursors appear with their names, and people can annotate slides using a pen, highlighter, or laser pointer; drawings can remain visible or fade away. Controls let the presenter decide who may change slides, draw, browse independently, or download, either for the whole group or individual people. Decks can be kept private, shared with selected people by email, or made accessible to anyone with the link. Presentation mode offers a full-screen view with the option to hide other people’s cursors, and updated deck versions can be uploaded while earlier versions and their drawings are retained.
