A WYSIWYG editor and presenter for decks written in markdown. Nothing is uploaded; everything stays in this browser, and Export always gives you files you own. Source on GitHub — MIT, one file, no dependencies. Built by Pavel Kordík.
Figures are SVG, never bitmaps — a deck has to stay readable to you, to git and
to the AI you ask to redraw something. 237 slides and 180 figures come to a megabyte, where
the same deck as .pptx is 34. The same bet as
pbook,
a book its readers and a model extend together.
To open a whole presentation, pick the one .json file in decks/.
For this keynote that is decks/great-convergence.json — it carries all 237 slides and
every figure in one file.
The AI here runs on capacity from CESNET e-INFRA CZ, with thanks. Nothing on this page needs it — the editor, the presenter and the exports all work without any AI at all. To use it, put your own endpoint under ⋯ → AI usage; there is a one-click preset for e-INFRA, which is free to anyone affiliated at a Czech academic institution.
Also accepted, dropped anywhere on this window: one or more .md files, a whole folder
of them (including a p-book content directory), and .svg files, which join the figure library.
