ShowSlide puts your slides on every device in the room, live, via a QR code.
Grounded in available product and source data
PowerPoint and Keynote control exactly one screen — the projector — while the room mostly watches from a distance; ShowSlide is built for live presentations on every device instead, sharing a QR code so each person follows the current slide on their own phone or laptop.
Writing the deck stays simple by design: slides come from an editor or pasted Markdown, and Live Sync reflects every edit or highlight in the shared session the instant it happens, so a presenter circling a key point mid-talk is something every viewer's screen shows immediately, not just the projector.
The audience side carries its own small but specific feature — live reactions let viewers respond with a like, dislike, or raised hand, visible to the presenter in real time, giving a read on the room that a silent video call or a physical audience often doesn't offer as directly.
Sessions extend past the live moment too: presentations can be embedded on a website via iframe or shared as a standing public link, and analytics tracks total sessions, attendance, and average session length afterward. Three tiers scale from a capped Free plan through Starter, which removes the session cap and adds a public link plus PDF export, up to Pro, which adds custom branding, an analytics dashboard, and live reactions on top of Starter.
No — the site states anyone with the session link or QR code can join instantly on any device, with no app download or account required on the viewer's side.
Yes — Live Sync reflects every change and highlight in the shared session the moment it happens, so a presenter editing on the fly doesn't leave viewers looking at an outdated slide.
Google Slides is built for asynchronous viewing of a deck; ShowSlide's own comparison frames itself around live audience sync specifically — every viewer's device follows the presenter's current slide automatically during a live session, which Google Slides doesn't do.
That's specifically the gap live reactions closes on a call where nobody's face is easily visible at once — a raised hand or a dislike from someone lost mid-explanation surfaces instantly, instead of only finding out at the end when someone finally speaks up.
Live presentations on Free are capped at 30 minutes per session with a maximum of 3 presentations total, which is worth checking against expected session length before relying on it for anything longer or more frequent.
