VizFlow is a web-based application designed to assist educators in creating visual STEM content. Its primary function is to convert text-based inputs, such as lesson notes, typed topics, or uploaded documents in PDF and DOCX formats, into narrated teaching videos or interactive animation pages. The tool is built for use in classrooms, tutoring sessions, and online course development. The platform automates video creation through a structured workflow. Users describe a topic or upload materials, and the AI extracts key concepts, writes a script, and generates the visual sequence. The output can be downloaded as an MP4 file or accessed as an editable HTML page, allowing for further customization of text, visuals, and timing. The tool supports multiple languages, including English, Chinese, Japanese, Korean, German, and French, with auto-generated voiceovers matching the selected language. Generation times vary, with HTML animations taking approximately two minutes and full AI teaching videos taking three to eight minutes. VizFlow is intended for a range of educational subjects, including physics, calculus, biology, engineering, and chemistry. It can be used to create short visual lessons for standardized test preparation, such as SAT, AP, and ACT exams, as well as for general classroom instruction and self-paced learning modules. The service does not require a credit card to begin use and is designed to be operated without prior technical expertise in video editing or animation.
