Problem
HTML presentations are portable, but not easy to polish.
A browser can display the deck, but display mode does not help you make the last-mile edits that a presentation needs.
Single HTML files are easy to share, but hard for non-code editing.
Generated slide sections need page management and visual controls.
A practical editor should keep the file local and export a portable result.
Workflow
The ProductStudio-style structure, focused on deck polish.
A clear sequence replaces the thin demo feel: open the HTML file, make precise slide edits, then export a portable deck.
02
Make visual edits
Use thumbnails, canvas editing, formatting controls, and image tools.
03
Download the result
Export the edited deck as a clean single-file HTML presentation.
Capabilities
The practical controls AI HTML decks need.
The tool stays narrow: final visual polish for a generated HTML deck, not another AI presentation generator.
Click-to-edit text
Select titles, bullets, captions, or labels and adjust copy, font size, emphasis, and color without touching code.
Image insert and positioning
Drop in a local image, keep it embedded in the deck, resize it, and nudge it into place.
Page management
Add, duplicate, delete, and reorder slides directly from the thumbnail rail.
Fit overflowing content
Reduce oversized text on the current slide when an AI-generated layout starts to overflow.
Block image export
Select a slide block and copy or download it as a PNG for reuse in documents, posts, or messages.
Clean HTML export
Export a single-file HTML deck that preserves the edited layout and embedded images.
Example
A browser workspace for portable HTML presentations
The editor treats slide-like sections as pages, so a single HTML file becomes a usable deck workspace instead of a static preview.
Editing path
route-specific proof, not keyword swapping
1
Detect section, article, data-slide, and .slide containers.
2
Use thumbnails to move through the deck.
3
Download the edited HTML without installing a desktop app.
Comparison
Built between AI generation and final delivery.
The product has a narrow job: keep the AI draft intact while a human fixes what needs visual judgment.
Generic HTML editor
Optimized for pages or code, not slide thumbnails and presentation polish.
Presentation software
Great for native decks, but importing HTML can break the design.
HTML slide editor
Keeps the HTML deck as the editing surface.
Use cases
For people who already have an AI-generated HTML deck.
The interface is built for the post-generation workflow: a usable draft exists, and now it needs controlled visual polish.
Open single HTML presentation files.
Edit section-based slides from AI output.
Insert local images and keep them embedded.
Export a clean deck for sharing.
FAQ
Questions before opening a local HTML deck.
Clear boundaries matter: this is a local browser editor for HTML decks, not a cloud storage or PPTX conversion system.
Can I edit text directly?
Yes. Open a sample deck or upload a local HTML file, click into the slide canvas, and edit text in place.
Can I change font size and color?
Yes. The editor includes text size, color, bold, and italic controls for quick final polish.
Can I move inserted images?
Yes. Inserted images can be resized from the canvas and nudged from the formatting panel.
Does it work with Claude-generated HTML?
Yes. Claude decks that use section, article, data-slide, or slide-like containers are split into editable pages.
Does it work with ChatGPT or Codex output?
Yes. The first version focuses on single-file HTML decks from AI tools such as ChatGPT, Codex, Cursor, Gemini, and Claude.
Will the design change after export?
The editor preserves the HTML structure and inline edits. Complex third-party scripts are removed for a safer single-file export.
Can I export to PPTX?
Not in the first version. The product is intentionally positioned as a safer direct HTML editing workflow before any PPTX conversion step.
Is my file uploaded to a server?
No. In this version, files are opened and edited in the browser. The landing page states this as a local-first workflow.
