lectureStudio vs Stream

lectureStudio is a free, open-source tool for presenting PDF-based lectures. It supports dual-screen presentations using a tablet, computer, or laptop with a projector, and presenters can mark slides with digital ink or highlights. The software records audio and video, then provides post-processing tools to correct slide errors without making a new recording. Students can participate in real-time quizzes and chat through smartphone browsers. Slides must be converted to PDF before use; the FAQ describes workflows for PowerPoint and LibreOffice Impress. Recordings can be exported as MP4 videos or lectureStudio .plr files for sharing through an LMS or file-sharing service. Institutions can host the software on-premise, and the maker says it can integrate with institution-wide Single Sign-On facilities. The maker labels lectureStudio GDPR compliant and says on-premise hosting can help address data-protection concerns tied to external services. It supports Windows, macOS, Linux, web, and self-hosted use, with live streaming listed. The project is on GitHub under GPLv3, and contributions are welcome. A FAQ and technical support contact are available.

Stream is a video platform for institutions creating and delivering learning content through an LMS. It synchronizes recordings from Zoom, Teams and Webex, processes them and publishes them to matching courses. AI features include transcription, captions and translation in 98 languages, meeting-level answers, searchable transcripts with timestamp jumps, topic chapters and automatically created highlights; the site reports 98% transcription accuracy. Its media library provides browser editing, trimming, role-based permissions, controlled sharing and analytics. Listed LMS workflows cover Moodle, Canvas, Blackboard, LTI and H5P, with dedicated Moodle plugins and automatic course matching. Stream is listed for web, API and self-hosted use, while deployment is described as cloud. There is no free plan, but a three-month Moodle pilot is offered without a credit card or commitment. Plans range from $29/month billed annually to custom enterprise pricing, with storage, integration, transcription and support differences.
