The ranking
How we decided #1. We rank on the 2 checks that decide whether a tool does this job: Structural & Tabular Formatting, Summary Output Quality. A check only carries a score when we recorded a finding for it, and a tool has to be measured on all of them to take the top spot. We also checked Active Recall Support (Quiz/Flashcards), Study Material Handling, Workflow & Revision Flexibility — compared for you, but not part of the ranking.

The tool handles YouTube lecture URLs, but it is limited to video-only input and does not support PDFs, images, multi-source integration, or other file-based academic documents, so its study-material handling is narrow rather than flexible.
▸Summary Output Quality2/51 struggled1 finding
Produces a summary, but it is paragraph-heavy and transcript-like rather than clear, revision-focused exam notes.
The generated output is paragraph-heavy and transcript-like instead of revision-focused notes, and the report says long lectures produce lengthy, cognitively heavy summaries that are hard to revise quickly.
▸Workflow & Revision FlexibilityCapability check1/51 failed1 finding
Offers no editing, highlighting, export, or offline-saving options, so revising the notes later is inconvenient.
This is a capability we checked per tool — whether (and how well) it supports this — so it shows a support verdict and what we found, rather than media or an input→output pair.
The tool provides no editing, highlighting, bookmarking, customization, or content-restructuring features, and it has no download option, no PDF export, or offline saving feature, so users cannot easily revise or personalize the notes in place and must return to the platform whenever they want to review the generated summary again.
