Presentations
A deck that is a link.
A presentation sent as an attachment gets opened on a phone, in the wrong app, with the fonts replaced. A presentation built as a website opens as you made it, on whatever it is opened on, and the version they see is the one you fixed at midnight rather than the one you sent at six.
Slides are blocks.
Each slide is a full-screen block: a title slide, a problem, three numbers, a quote, a timeline, a close. Components decide how each type of slide looks; the block's form holds its words and images. Reorder slides by moving blocks up and down, hide the one you are not sure about, and keep a switcher where the same slide needs a different version for a different room.
Anchors on each block give every slide its own address, so "jump to the pricing slide" is a link, not a scroll. AI generation will draft a first deck from an outline; the menu window can build a table of contents from the anchors.
One deck,
several audiences.
Clone the page for the board, the investors and the team, then change what each needs: numbers for one, roadmap for another. Clone and translate a page when the next audience reads another language, with DeepL for speed or an LLM.
Share it on a hidden preview with a preview code while it is still being argued about, then publish to cstmui.com when it is ready to be forwarded.
Give the project a Web App Manifest and the presentation can be installed like an app. Turn on the service worker and it opens without a connection — useful in exactly the conference room where the Wi-Fi password is on a card nobody can find.

Worth knowing
What the website format adds.
Images and video
From the media library, AI-generated or from royalty-free stock, with the licence question already answered.
A proper share card
OpenGraph title, description and image, so the forwarded link previews as a deck and not as a bare address.
Installable, offline
Web App Manifest in project settings, service worker as an output switch. See publishing.
Which plan
Regular, €100 a month, covers blocks, clones, translation, preview codes and publishing. The service worker and the other advanced output switches are part of PRO at €300, so offline decks need PRO. Compare plans.
Questions
Can people see it without an account?
Yes. A preview code link or a published cstmui.com address opens in any browser.
Can I keep one slide private?
Hide the block. It stays in the editor and is left out of the page until you show it again.
Can it be printed or exported to PowerPoint?
castomUI publishes websites; it does not claim a PowerPoint export. The browser's own print is the route to paper.
Field note: the question at the end is always about the slide you hid. That is why hidden is not the same as deleted.
Your website next.
Start it today.
Open the editor, describe the website, and publish the first version to a cstmui.com address.
