Presentations that stay private until you present them.
Prismara Lumen is the presentation app in Prismara Work. Build decks together, add animations that bring points in one at a time, and present with speaker notes in presenter view, while the content stays encrypted on your team's devices. PowerPoint and OpenDocument decks open and save both ways.
What Prismara Lumen does
Build animations
Entrance, emphasis and exit effects that run on click, with the previous or after it, including paragraph-by-paragraph builds.
Animations panel
See and reorder every effect on a slide in one place.
Presenter view
Present with your notes and what comes next on your screen while the audience sees the slide.
Notes pages and handouts
Print speaker notes pages and audience handouts straight from the deck.
PowerPoint and OpenDocument
Decks open and save as .pptx and .odp, so you can take existing presentations with you.
Co-editing
Build a deck together in real time, merged without the server seeing the content.
How it's secured
Prismara Lumen follows the engineering rules shared across the suite, plus these product-specific measures.
Encrypted on your device
Slides, notes and images are encrypted before they leave your device; the server stores ciphertext only.
Signed edits
Every author's changes are signed and chained, so altered or withheld edits are detected.
Post-quantum key exchange
Deck keys are shared with a hybrid X25519 and ML-KEM-768 exchange.
