ChangTu AI

Built by the Mockplus team, ChangTu AI is designed for knowledge workers who need to visualize ideas quickly. It accepts multimodal inputs—text, PDFs, PPTs, Word files, images, web URLs, and spreadsheets—and uses AI to parse content logic, generate structured diagrams, and even fill in missing steps. Users can switch between mind maps, flowcharts, kanban boards, and Gantt charts in one click, saving hours of re‑drawing. In tests, a 800‑word product document produced a 4‑level mind map in about 12 seconds with high accuracy.

Pros: No design skills required; context‑aware multi‑turn conversation helps refine diagrams; smart layout algorithms ensure professional outputs; likely supports exports to common formats such as PDF and long‑image. Cons/Limitations: Offline use is not mentioned, so an internet connection is required; deeply customized styling or extremely large and fine‑grained diagrams may stretch its capabilities; pricing (free tier availability, subscription model) is not disclosed in available evidence—potential users need to verify on the official website.
