Show HN: SlideBySide – Present slides without sharing your screen

SlideBySide is a platform that allows users to present slides without sharing their screen, enabling co-hosts to control the current page in real-time. The platform supports various file types, including PDF, PPT, and PPTX, and allows users to upload files from Google Drive or OneDrive. Key features include live cursors, shared control, drawing tools, and the ability to decide who can change slides or download the presentation. The platform is user-friendly, with no need for installations, meeting software, or accounts for the audience. Users can share the link with anyone, and new versions of the presentation can be uploaded while keeping old ones with their drawings.
