Cool Tool | imageFrom the founders of, a visual collaboration platform, comes a presentation tool for teachers to present their documents, slides, etc., live to the class synced across iPads, mobile devices and laptops. Students can make their own personal notes to slides and the whole class and teachers can discuss the presentation topic in a real-time chat. When the presenter changes the slide, it automatically changes on everyone’s device instantly. “It’s a valuable tool to make students more engaged in class and to be able to discuss the topics further after the class is over,” says Cathrine. “It’s also great for long-distance presentations — students who are ill will be able to view the presentation synced to their own device at home.” They introduced a synced presentation mode inside CanvasDropr but a lot of users and customers requested it as a separate product, and that’s how came along, explains Cathrine Andersen, 25, a co-founder with Christian Rasmussen, 28. They founded the company in late 2011 and now have users and customers in 140 countries; recently, PCMag named them one of the best Web Apps of 2013. “We’re excited about our newest release, and look forward to making presentations more engaging all over the world,” says Cathrine. is being used at MIT, Harvard, Stanford and other prominent universities as well as in K-12 education. Presenters can upload presentations for free but the standard free accounts will disable presentations after 48 hours. To keep presentations, comments and notes available forever, presenters can upgrade for $14 per month. Tell them you saw it here and you’ll get a 50 percent discount on a Pro account.
