Sylly scans a college or high school syllabus and uses AI to pull out the course name and the assignment titles, types, and due dates. To test without a physical syllabus: open the Scan tab, choose "Photo Library," and pick any image of a syllabus. "Import PDF" works the same way with a PDF file. An example syllabus is attached to this submission. No account or login is required. This version has no user-facing changes. Syllabus text is sent to a server we operate, which forwards it to Anthropic's Claude API and returns the result. This is described in the privacy policy.

Verdict
The clearest difference is ads: Sylly at none against Course Sync's shown. Sylly also leads on ratings volume (51 vs 3) and monetization model (free vs ad-supported). Course Sync's advantage is review sentiment (67% vs 50%) and update cadence (every 4 days vs every 2 weeks). On price, rating and in-app purchases there is nothing between them.
