SlideBySide - Collaborative slide presentation without screen sharing
Show HN: SlideBySide – Present slides without sharing your screen
SlideBySide revolutionizes presentations by letting you share slides via a link instead of sharing your screen. Upload a PDF or PowerPoint, and your audience joins instantly in any browser—no sign-up needed. Everyone follows the same slide with live cursors, shared control, and drawing tools. You can set permissions for who can change slides, draw, or browse independently. With features like presentation mode, version history, and cloud import from Google Drive or OneDrive, SlideBySide makes collaborative presenting seamless and engaging. Perfect for remote teams, classrooms, and any scenario where you want to present together, side by side.
Don't share your screen. Share your slides.

Just a datapoint but Microsoft Teams (most commonly paired with users of Powerpoint) has an option to share and present just a slide deck where viewers can tag along the presenter or jump forward and back to view the rest of the deck independently from presenter.
But in quite a few cases presenter would want to control when information is presented/revealed to audience.

This looks clever. I've seen PPT to web tools before (https://sparkslides.com/publish/, https://slidehtml5.com/), but I think the slide synchronization idea is new. I can't evaluate more than that as I don't use these.
In the past I have liked marp (https://marp.app/) for technical slides as you write in markdown, can use version control, etc. Powerpoint always felt odd as a developer.
To share public slides I've published to GitHub pages (https://github.com/robalexdev/marp-to-pages). I've seen professors use it for all their slides. But that doesn't synchronize slides, last I checked.
