SubShort

SubShort is a courses tool that turns any topic or course file into a video quiz in minutes. SubShort generates interactive video quizzes, AI video stories and styled subtitles from a topic description or an uploaded PDF or Word course file, aimed at short form creators and students who want revision material in a watchable format.

SubShort is a browser based content generator built around short form video. It targets two audiences that rarely share a tool: creators who need a steady stream of watchable clips for TikTok, YouTube Shorts and Instagram Reels, and learners who want revision material in a format that does not feel like a textbook. The homepage states that more than 10,000 creators already use the product, and the central promise is a finished quiz or story in roughly three minutes. The video side of the product comes in several formats. Users can build multiple choice quizzes, true or false sets, riddles, would you rather comparisons and language vocabulary checks, each rendered as an interactive video rather than a static worksheet. A separate AI Video Story mode produces narrative clips instead. On top of the quiz output sits a subtitle engine: subtitles are generated automatically, can be translated into more than 10 languages while keeping their original timing, and can be restyled with custom fonts, colors and animations. A live preview shows every change as it is made, so styling is adjusted on the fly rather than exported and re-checked. The study workflow is the most distinctive part. Users upload course material as a PDF or Word file, or simply describe a topic in text. SubShort then generates a personalized revision quiz in video form, with questions presented in an interactive format the learner progresses through. This puts the tool in the same conversation as flashcard and quiz generators, but with the output wrapped in motion and narration rather than plain cards. Creator oriented alternatives tend to focus on captions or clipping alone, while education tools rarely produce anything designed to be watched. Anyone comfortable uploading a document and choosing a template can operate it, and the automated subtitle and quiz generation removes most manual editing. Customization is offered but not mandatory. The product is web only, and the homepage does not publish pricing figures, integration details or a support structure beyond a plan selector, so buyers should check the app directly before committing.
