Presentations, from a conversation
An agent writes the presentation with you, in words; this server makes the file, keeps the shared ones and lets people edit them together. A presentation is a link: whoever has it opens it.
Nothing to sign up for here. The links come from the conversation — a deck to open, a source to download, an edit link to share, a drop box for your pictures.
The format behind it, .jmd, is open: Markdown with blocks, rendered on-brand by a self-contained runtime. It lives at github.com/Jamespot/jamespot-jmd.
