Live presentation software: design the deck, then present it live

What is live presentation software?

Live presentation software has two jobs, and most products only do one. The first is authoring: building the slides and, ideally, the motion on them. The second is running the room: getting an audience onto that exact deck at the same moment and giving them a way to respond. A tool that does only the first is a design app; a tool that does only the second is a meeting app. Live presentation software is the pair, held together on one deck.

That is the line the two incumbent camps fall on either side of. Authoring tools — PowerPoint, Google Slides, Canva — produce a beautiful file and then leave you to find an audience for it; there is no roster, no raised-hand queue and no moderator role anywhere in them. Meeting tools — Zoom, Livestorm, Webex — run the room but have nothing to author with, so a file built somewhere else gets pushed through their screen-share and the audience watches a compressed picture of your monitor.

One thing here is deliberate and worth stating before you invest a deck in it: a deck can never leave the product as a file or a link. There is no export — no PNG, PDF, MP4 or PPTX — and no project download. A published deck does have its own URL and an embed code; what never exists is a file. The only way a second person ever sees your deck is by joining a live session, so the single distribution channel is the join code itself.

How live presentation software differs from a slide tool or a meeting tool

Most tools sit in one of two camps, and the row that matters is whichever one you are leaving.

	Slide tool (PowerPoint, Google Slides, Canva)	Meeting tool (Zoom, Webex, Livestorm)	DeckSlide
Builds the animation	Yes, within fade and fly-in	No	Yes — keyframes, motion paths, true shape morphs
Gets an audience in	No	Yes, by meeting link	Yes, by 8-character code, link or QR — no account
What attendees see	A file you sent them	A compressed video of your screen	The real deck, rendered in their own browser
Audience response	None	Chat, reactions	Chat, private 1:1s, hand queue, polls and quizzes, captions
Recording / replay	n/a	Yes	No — nothing is captured to video
Export as a file	Yes	n/a	No — a deck never leaves as a file or link

The last two rows are the trade. Everything above them is why the trade can be worth making, and if either bold cell is disqualifying for you, this is the wrong tool and better to know now.

How do people join a live presentation?

Getting an audience in is the part most tools make heavy, so this one keeps it to a code. Schedule a talk and you get three interchangeable ways in: an eight-character code, a join link for that session, and a QR code you can drop on a poster, a slide or a message. An attendee types the code or scans the QR, enters a display name, and they are in the room. There is nothing to install and no account to create — for them, or, to try it out, for you.

Early arrivals do not stare at a dead page. They land in a lobby that shows a live countdown to showtime and how many other people are already waiting, and it moves everyone into the talk automatically the moment you begin.

Be clear about the other half of this, because it is a real constraint: the product never sends anything to anybody. There is no confirmation, no reminder and no go-live alert, because there is no mail transport of any kind. Handing out the code, link or QR is a manual step you take through whatever channel you already use, and it will stay that way until that changes.

What does the presenter see while presenting?

The presenter console is a control surface, not a teleprompter. Two clocks run while you talk: one for how long you have been on the current slide, one for how long the whole talk has run. Both survive a reload of the console, so refreshing the page mid-session does not reset your total back to zero.

Beside the clocks is a live attendee list with presence, so you can see who has actually joined and who is connected right now rather than guessing at a silent room. You drive the deck with the keyboard or an on-screen dock — play, pause, forward and back — and you can point and draw straight on the live slide: a laser for a moving reference, a pen for a mark you want to keep, a highlighter over text, all wiped with one click when the slide turns. Those marks land at the correct spot on every attendee’s screen whatever size their display is, so a phone viewer sees the circle around the same figure a laptop viewer does.

What the console does not give you is a script. Speaker notes sit on the console for the slide you are on, and the audience view is built from the document with them stripped out, so they cannot reach the room by accident.

Do you have to screen-share to present live?

This is the structural difference, and it is the strongest single reason to present here rather than over a meeting tool. Nobody screen-shares. Your audience is not watching a compressed video of your monitor; each attendee’s own browser renders the actual deck, synced slide by slide from your controls. The animation survives the trip intact — keyframed motion on curved paths, true shape morphs, clipping masks, blend modes and frosted-glass effects all play at full fidelity on their screen, not as the smeared artifacts a video pipe leaves behind. Click-advance holds are preserved too, so a slide set to wait for you genuinely waits.

There is a quiet benefit in this: because no screen is being shared, your console is never on anyone else’s screen. The audience sees the deck and only the deck — never your notes, your other windows or a stray notification.

Say the flip side plainly, though, because it catches people out. Screen sharing is available as an opt-in stage source rather than the default. You cannot share your desktop, and you cannot demonstrate another application, a website or a document during the talk. The only thing the room can see is the deck you built here, playing live.

Can the audience respond during a live presentation?

Your microphone and webcam run alongside the deck, not instead of it, and a participant strip highlights whoever is speaking. Each viewer independently balances your voice against the deck’s own soundtrack, so someone on headphones and someone on laptop speakers can each get a mix that works. You can also hand attendees a microphone and a camera of their own, which is the switch that turns a broadcast into a conversation.

Around the deck sits the rest of the room. Everyone talks in a public chat; any attendee can also open a private one-to-one thread with you or a colleague, and every one of those threads collects in a single staff inbox so your team can pick them up together. Raised hands form an ordered queue you work through and mark handled. One button turns on live captions for the whole audience and keeps a searchable transcript of the talk afterwards. Host A/V controls let you mute everyone, stop all audience video, or hide attendees from each other in a single click, and anyone who joins later arrives under the same rules.

Know the edges before you are mid-talk. There is no recording and no replay — the session is not captured to video at all. Live polls, quizzes, ratings and word clouds do run, but the question has to be authored onto a slide in the studio beforehand — there is no box for writing a new one mid-talk. There are no emoji reactions and no upvoted Q&A queue. And the text room has no moderation: you cannot delete a message, mute one individual or remove anyone from chat. The host controls are blunt instruments — they act on everybody at once — so you set the tone by talking, not by policing.

Can someone else help you run the talk?

When you want help running a talk, you send a colleague a per-talk invite link. There are two kinds, and the difference is the point. A cohost link lets someone drive the slides and work the chat alongside you. A moderator link is narrower: chat and the raised-hand queue only, with no control over the deck.

That split is not a UI convenience a determined person could click around — it is enforced on the server. A moderator provably cannot advance your slides, because the limit lives behind the scenes and not just in what the interface chooses to show. Each link is scoped to one talk, so the grant ends when that session does.

Two honest caveats. The links have to be copied and pasted by hand into your own message to that colleague; nothing is sent for you, because the product has no mail transport. And there is no standing team you can build once and reuse across every talk — the invite is per-session, every time, until that lands.

What happens when the talk ends?

Ending a talk actually ends it. The room closes for good and you are left with an honest attendance list, rather than a session that stays nominally open forever with a roster nobody trusts. If you had captions on, the transcript is kept and stays searchable inside the product.

Be clear about what you are not left with. There is no recording and no on-demand replay — nothing was captured to video, so there is nothing to re-watch. There is no analytics or engagement dashboard, no CSV of who attended, and no way to send anyone anything after the fact, because the product has no mail transport. What happens in the room stays in the room, and once the room is closed that is the end of it.

One rough edge to plan around honestly: when you end, the audience is currently left looking at your last slide rather than being told the talk is over. So make your last slide the goodbye — a thank-you, a next step, a where-to-find-you — and end on it deliberately.

For the arguments behind all of this, the browser-only case explains why nothing installs, the no-signup studio lets you build before you commit, the QR join page covers getting a room in fast, and the webinar walkthrough runs the whole thing end to end.
