Free Canvas
An AI canvas that combines Wenku, Netdisk, and multimodal inputs to help students, office workers, and research-heavy users produce PPTs, long-form writing, and organized material faster.
Tool overview
Based on the available evidence, Free Canvas is best understood as a material-centric AI creation canvas, not a simple chat assistant or a standard online whiteboard. The stronger evidence comes from multiple Zhihu hands-on posts: its core value is not fully autonomous agent behavior, but placing documents, PDFs, PPTs, web links, audio/video, and Baidu Netdisk files into one shared context, then using selection, grouping, and prompting to generate the next output. A more accurate analogy is an AI research-and-writing workspace with multimodal grounding, not a design collaboration board like Figma or Miro.
In practical use, the evidence consistently points to three outputs: generating PPTs from mixed materials, writing summaries/outlines/articles from selected passages, and organizing research reports, financial reports, study notes, or evidence files. Several posts highlight “select specific content, then generate from it” plus Wenku-Netdisk integration as the real differentiators. That suggests it is most useful for people who already have a lot of source material but lack a unified interface for synthesis and repurposing.
