Banana Slides is a Python-based web application for generating presentation slides using AI. The project is primarily documented in Chinese. Its core purpose is to let someone describe a topic or upload reference material and have the system produce a finished, visually coherent slide deck in minutes, without needing design skills or manual layout work.

The tool supports three ways to start: typing a single sentence about your topic, writing out a rough outline, or describing each slide individually. In all cases the AI generates both the structure and the visual content. You can upload documents in formats like PDF, Word, or Markdown, and the system extracts key points and images from them to populate the slides. You can also upload a reference image or template photo to guide the visual style of the output.

One of the design goals is natural-language editing. Rather than clicking through menus, you can tell the system things like "change this chart to a bar graph" or "turn the third slide into a case study" and it will update accordingly. The result can be exported as a standard PowerPoint file that you can open and edit further in any presentation software, or as a PDF ready to present directly. There is also a feature that converts the finished slides into a narrated video with AI voiceover, subtitles, and animated transitions.

Deployment is offered through Docker Compose for self-hosting. Docker is a tool that lets you run software in a self-contained environment without manually installing all its dependencies. A one-click cloud deployment option through a hosting provider is also mentioned for users who prefer not to manage their own server.

The README notes several features still in development at the time of writing, including web search integration, an agent mode, online playback, and slide transition animations.
