Animated slide decks in your browser, free and open source
OpenSlides, at openslides.dev, is a presentation studio that runs in your browser tab. Paste your notes or load a Markdown file, check the slide-by-slide plan, and pick one of four looks. A first deck needs no AI model at all. Every slide can move: motion backgrounds, kinetic type, charts that race, maps, diagrams that draw themselves, and widgets the presenter operates, such as sliders, spin wheels and quizzes. The presenter view keeps your notes, the next slide and a timer on your screen. Each slide's notes become its script. Record it in your own voice, use a voice that runs in the browser, or dub it into another language, then export the deck as an MP4 video. You can also import a .pptx, and export a static .pptx or a PDF. AI is optional. Add your own key for Anthropic, OpenAI or OpenRouter, or point it at a local model, and the studio shows an estimate before each turn. Decks, images and recordings stay in your browser, and there is no account. OpenSlides is open source under MIT or Apache-2.0. OpenSlides (openslides.dev) is an AI tool for presentation software, useful for teams comparing focused Productivity apps in a curated AI tools directory.
