History Timeline vs Scrivium

History Timeline is desktop software for creating and exploring interactive timelines about history. Its time-zoom interface ranges from very long historical spans to events measured in yoctoseconds. Users can begin with an Excel template, import data as CSV, and add events, icons, hyperlinks, styles, and event hierarchies. Timeline items can link to online articles and original documents. The site provides timelines covering world and United States history, geology, science and technology, biographies, and art history. Finished timelines can be saved as JPG or PNG images, or printed across multiple pages with configurable paper size, orientation, and margins. Online display and website embedding, including customized timelines, are available by request. The software runs on Windows 11, 10, or 8 and macOS 10.15 or later, with at least 2 GB RAM and 400 MB free storage. A free version has limited features and content; Personal costs $24.50 a year, Professional $49.50 a year, and Perpetual 119.50 USD one-time.

Scrivium offers study guides and interactive lessons in history and literature, with guided paths through the material. Lessons pair brief readings with questions and activities; learners can read or listen at their own pace. The app listing describes daily lessons of 5 to 10 minutes, three-week guided journeys featuring historical figures, and practice sessions based on methods associated with those figures. A personal commonplace book holds saved lines, reflections, and practices. Study guides are free to read, and opening lessons from released courses are available without signing up. Users can unlock titles with credits purchased once or through a yearly Early Believer plan; unlocking provides lifetime access and updates. Credits generally expire 12 months after they are granted, and unused membership credits expire at the end of the billing period after cancellation. Scrivium is available on Android, iOS, and macOS. Individual account holders must be at least 13 unless a parent, guardian, or authorized school arrangement applies. Its terms say user inputs and outputs may be used to provide and improve the service, with an email opt-out for improvement use.
