What our research says

Eightify

A narrow tool that does one job well: decide whether an hour-long video is worth an hour before you spend it. The timestamped key points are the real feature, because they let you jump straight to the section you actually needed. The catch is that it is subscription-only for a job several free extensions and general assistants now also do.

Pros

Key points come with clickable timestamps, so the summary doubles as navigation
Handles very long recordings rather than capping at a few minutes
Output available in roughly 40 languages, including summarising an English video into another language
Works inline on the YouTube page instead of asking you to paste URLs elsewhere

Cons

No permanent free tier — after the trial it is pay or nothing
Summary quality is bounded by YouTube's auto-captions, which are poor on accented or technical speech
The vendor blocks automated access to its own site, so pricing and terms are hard to verify independently

Glasp

Glasp fits students, researchers and writers who read a lot online and want every quote kept with its source and searchable later. People who want their reading private by default, or who mostly need a full note editor rather than a highlighter, should look elsewhere.

Pros

Free plan keeps unlimited highlighting plus exports and Notion sync
Works across Chrome, Safari, Edge, Brave, Firefox, Opera and mobile
Each highlight keeps its source metadata, so quotes stay cited
MCP connector and API make the library usable from other AI tools

Cons

Highlights are public by default; privacy is a paid feature
Free AI allowances are small, especially video summaries
Social feed is of limited use to people who read alone
