# Lorea > Lorea is an AI course platform. For learners, it transforms PDFs into interactive study materials — games, quizzes, videos, songs, podcasts, summaries. For teams and companies, it turns SOPs, handbooks and policies into employee training courses with knowledge checks and completion tracking. Free plan available. ## For Teams (employee training) Lorea for Teams is an AI training platform for teams: you upload existing company documentation (SOPs, employee handbooks, policies, product manuals, slide decks or a URL) and Lorea generates a structured course with lessons, summaries and knowledge checks, gives you one link to share, and tracks who completed it. It is built for teams of roughly 2–200 people that have no dedicated L&D or enablement function. It does not provide SCORM/xAPI export, certification-with-expiry workflows, or org charts. Pricing: free plan available; the Lorea for Teams plan is USD 99 per month for 5 seats with unlimited course generation and unlimited file uploads.
