DeepSeek Harness sprouts a visual editor for real design files
It turns DeepSeek's chat interface into a studio for generating, refining, and exporting actual editable designs and slides.

What it does
DeepSeek Design is a set of three plugins—deepseek-idesign, deepseek-ippt, and deepseek-ivideo—that add a native visual studio to DeepSeek Harness. You describe a website, poster, presentation, or video in chat; the AI generates HTML, CSS, and project files in your workspace; then you open a Design, PPT, or Video view to tweak the result visually or ask the AI to edit a selected element. The output stays as real, editable workspace files rather than static screenshots.
The interesting bit
The workflow treats Harness as the brain and iPolloWork Studio as the hands: AI moves from intent to artifact, you move from artifact to detail, and the loop repeats. A “selection-aware Ask AI” feature lets you click a single heading or image and draft a targeted change without rewriting the whole project.
Key highlights
- Three isolated plugins for design, slides, and video that share a protocol but keep project directories separate
- Native Harness integration reusing the current conversation, model, and workspace permissions
- Real workspace files with undo, conflict detection, and atomic template replacement
- Dedicated template markets for each format; PPT exports to PDF and PPTX
- Video plugin uses a HyperFrames timeline with 28 templates and auto-validation
Caveats
- DeepSeek Harness is still in developer preview, so compatibility may shift
- Requires Node.js
^22.19.0or>=24.0.0 - Licensed under iPolloWork Source Available License, not a standard OSI-approved open-source license
Verdict
Worth exploring if you want DeepSeek to produce deliverable designs and decks you can edit later. Skip it if you need a standalone tool—this is strictly a Harness plugin.
