Flash Papers Turns Academic Papers Into Interactive Explainers

Summary

Flash Papers is a web service that turns academic papers into interactive explainer sites generated from a PDF link. Users can paste an arXiv or ChinaRxiv URL and receive a page that presents the paper’s central idea, method, and quantitative details through charts, scrub-able diagrams, sliders, animated explanations, and small live demonstrations. The service says it already has more than 100 interactive papers available to browse, including examples covering LoRA, diffusion models, and reinforcement learning with verifiable rewards. Its stated workflow is designed to consider the whole paper, including methods, figures, and appendices, rather than relying only on a short abstract. Flash Papers streams the selected model’s generated page as it is written and describes the process as taking seconds rather than waiting for a completed render. Users can sign in with Google and bring an API key from Google AI Studio, Anthropic, or OpenRouter. Provider charges depend on the selected model, paper length, and generated output, including reasoning tokens, so users are directed to check current provider pricing and limits. The site identifies Gemini, Claude, and GPT as the models powering its interactive explainers.
