Edit Banana Introduction and Tutorial: Convert AI Images and Presentations into Fully Editable PPT, XML
Edit Banana is a tool centered on “making uneditable content editable.” It is primarily used to automatically convert static content—such as flowcharts, architecture diagrams, and technical illustrations found in AI-generated images or PDF presentations—into editable DrawIO or PPT files.
The core technology integrates SAM 3 (Segment Anything Model) image segmentation, multimodal large language models (such as GPT-4V and Qwen-VL), and OCR text recognition services. It can identify shapes, arrows, text, and hierarchical relationships in images, and reconstruct the original layout logic and styling as faithfully as possible. In other words, it is not merely image-to-text conversion, but “structural reconstruction,” enabling each element and object to be selected and edited individually.
Edit Banana now offers a web version for online use; after uploading an image or PDF, an editable file is generated within seconds.GitHub This version supports local deployment, making it suitable for users with GPU environments or enterprise needs.
