Host slides that always stay current
Upload a single HTML file, ZIP, or folder. Every upload becomes a new revision, so your audience always opens the latest version — and you can roll back anytime.

Welcome everyone. Today we'll walk through how Prezzly turns any HTML deck into a professional, live presentation experience.
Everything you need to present HTML decks
One platform to host your slides, deliver them live, and share them securely — so you can focus on the talk, not the tooling.
A presenter view that has your back
Speaker notes, slide thumbnails, a talk timer, laser pointer, and pen. Everything you need to deliver a confident talk lives on one screen.
Keep every viewer in sync, live
Your slides, laser, and pen strokes stream to the audience in real time — whether they're in the room or joining from the other side of the world.
Share securely, stay in control
Send view-only links or invite collaborators by email. You decide exactly who can see each deck — no accidental edits, no leaked slides.
Turn Q&A into real engagement
Let viewers pin questions directly on your slides. Reveal and answer them when the moment is right, and close the loop before you move on.
Create decks with AI, publish in one step
Connect your AI tools and generate, upload, and update presentations without copy-paste. From prompt to published deck in seconds.
From HTML file to live presentation in three steps
No setup wizard. No desktop app to install. Just upload your deck and present.
01
Upload your deck
Drag in an HTML file, ZIP, or folder. Prezzly hosts it instantly and versions every upload, so iterating is effortless and nothing gets lost.
02
Present with control
Open presenter view and take the stage. Notes, timer, laser, and pen keep you on track and make every talk feel rehearsed — even when it wasn't.
03
Share and go live
Send a secure view-only link or start a live session. Your audience follows every slide and annotation in real time, wherever they are.
AI workflows
Let AI build the deck. Prezzly hosts and delivers it.
Connect your AI tools once, then create, upload, and update presentations without ever leaving your workflow. Reusable brand templates keep every deck on-message.
Publish straight from your AI assistant
List, create, and upload presentations directly from the AI tools you already use. Your assistant becomes a one-command publishing pipeline.
Programmatic access when you need it
Generate API keys for full, secure access to your presentations, revisions, and speaker notes — perfect for automation and custom workflows.
On-brand decks, every single time
Generate presentations from a template package with your styling and brand guidelines built in. Consistent, professional output without the manual work.
Reusable brand templates
Upload style packages once and every deck your team ships looks like it came from the same design system. Brand consistency on autopilot.

Audience engagement
Presentations that spark a conversation
Don't just broadcast slides — engage the room. Live sync and slide-level Q&A keep your audience involved from the first slide to the last.
Real-time slide sync
Every slide change, laser stroke, and pen mark reaches your audience the instant it happens — in the room or joining remotely by link.
Questions pinned to your slides
Viewers drop questions exactly where they matter. You choose when to reveal and resolve them, so you stay in charge of the flow.
Q&A you can revisit later
Every talk keeps its own question session. Follow up after the event or answer live from the presenter panel — nothing slips through the cracks.
Enterprise-ready. Zero friction.
The security your IT team expects, without the setup your team dreads.
Single sign-on
Log in with your existing work account. No new passwords, no credential sprawl — access stays managed by your organization.
Fast and reliable everywhere
Your decks load instantly for audiences anywhere, with data hosted in the EU. Built to stay online exactly when it matters most.
Access on your terms
Share decks through secure view-only links. Viewers watch without an account, and you stay in full control of who sees what.
