Alexandria is a reading platform built around a simple observation: people read more than ever and remember less than ever. The average person forgets most of what they read within a week. Not because of a memory problem. Because the tools were designed for consumption, not understanding. Alexandria brings articles, podcasts, YouTube videos, books, and PDFs into a single library. It reads content aloud with synchronised word-by-word highlighting so you stay focused. Then it goes further. The platform automatically extracts key concepts from everything you consume, connects related ideas across different sources, and uses spaced repetition to bring knowledge back before you forget it. The project started as FlowRead, a Chrome extension that combined text-to-speech with real-time word highlighting. The founder, Elliott Tong, built it after struggling to read technical documentation post-workout and realising no tool on the market would read with him rather than just at him. The extension worked, but it revealed a deeper problem. Knowledge is scattered across dozens of apps and none of it connects. Read-it-later tools optimise for clearing backlogs. Note-taking apps become graveyards. AI chat tools give answers that vanish into conversation threads you never revisit. Alexandria is named after the ancient library because the mission is the same: one place where understanding can live, be accessed, and be built upon. It is designed for students, professionals, ADHD readers, and anyone who consumes knowledge across multiple formats and wants it to actually compound over time.

FairwAI is building real-time accountability infrastructure to detect bias in the moments that matter most. We’re solving one of the toughest challenges in tech: how to make fairness not just a principle but a system. From healthcare and hiring to hospitality and housing, bias shows up when people are most vulnerable. FairwAI turns those moments into measurable, actionable data—using AI, computer vision, and behavioral science to flag risks and enable institutional change before harm happens. We’re not a DEI tool. We’re compliance infrastructure for a new era—where safety, dignity, and fairness are non-negotiable. Our team includes engineers, policy thinkers, civil rights advocates, and public interest technologists from MIT, Harvard, Stanford, The UN, and beyond. We’re launching high-impact projects and building the backbone of ethical AI adoption across sectors. For interns & fellows, this is not a coffee-run experience. You’ll co-design tools, analyze live scenarios, and help shape the future of bias detection and remediation. Your work will be mentored, respected, and turned into real-world impact. If you care about fairness, ethics, and building tools that actually change lives—FairwAI is where your skills meet purpose. Join us. Let’s build the infrastructure fairness deserves.
