Sci-bot.ru lets you grab paywalled research papers without a university login. Behind the interface sits a network of automated crawlers that punch through publisher paywalls. Once you paste a DOI or paper title, the site pulls down the PDF from library subscriptions, preprint servers or mirror sites. On testing, it delivered articles from Elsevier, Springer and Wiley within seconds, even for brand-new publications. The project runs on donated server time spread across Europe and Asia, keeping costs near zero. Its codebase, hosted on GitLab, ties into Telegram bots so you can request papers right from a chat window. Traffic stats show about 500,000 downloads in the past month, with users in India, Brazil and Russia making up half of that. Publishers have already sent DMCA takedown notices, but the site simply spins up new mirrors when one goes down.
