Make the deck a living system.
Vessica Studio connects ordinary HTML and Markdown files to a visual editor, reusable style templates, audience insights, repeatable Codex workflows, and a voice agent that can listen, navigate, edit, and help you present.
One presentation, four ways to work
Start in the browser, continue in Codex, refine from the CLI, and present with Vessica. Every surface writes back to the same understandable content model.
- Visual editing with frequent automatic saves
- Reusable workspace and built-in style templates
- Companion files for evidence and talk track
- Local-first creation with hosted projection
- Voice-aware presenting and editing
Choose your starting point
Use the web editor
Create from a template, edit slide objects, work with companions, share, present, and export.
Choose a visual system
Start with an included style or teach your workspace a visual language from Markdown, PowerPoint, or a website.
Understand your audience
See which registered viewers returned to a shared or public presentation and when.
Install the tools
Install the vstd CLI and the Vessica Studio plugin for Codex.
Build with Codex
Use six purpose-built skills for new decks, edits, reviews, forks, additions, and market refreshes.
Present with Vessica
Let the voice copilot follow your talk track, move through the deck, highlight ideas, and make edits on request.
What stays under your control
The source of truth is a content repository. Each slide is an HTML fragment paired with a Markdown companion that records intent, evidence, sources, visual direction, talk track, and edit history. Git makes the deck diffable; the CLI makes it buildable; the browser makes it tactile; Codex makes the workflow agent-ready.
The hosted Railway instance is a projection of that repository. Presenter-only saves can be synchronized back to Git, while audience links remain signed, deck-scoped, and read-only.
A quick first run
go install github.com/vessica-labs/vessica-studio/cmd/vstd@latest
vstd init my-studio
cd my-studio
vstd new product-story --title "Our Product Story"
vstd serve product-storyOpen http://localhost:4400/d/product-story/, then use the editor yourself or ask Codex to build the narrative with the deck-new skill.
