Write a presentation as plain text and present it from the browser. Split slides with ---,
get a live thumbnail rail, speaker notes, a run timer and full-screen mode, then export a single
self-contained HTML file you can email or host anywhere. No account, no upload, no £12/month slide app.
While presenting: → / Space next, ← previous, Home/End first and last, S speaker notes, F full screen, Esc exit.
The format is deliberately small: # title, ## subtitle, - or
1. lists (indent two spaces to nest), > quote, triple backticks for code,
**bold**, *italic*, `code` and [text](https://…) links.
A line beginning Note: is a speaker note: it never appears on the slide. The exported HTML is
one file with no external requests, so it works on a plane and on a conference laptop with no network.
