Which one is for you
Pick Glasp if
- Fits if you collect quotes from articles, PDFs and YouTube and don't mind them being public
- Works for people who send highlights on to Notion, Obsidian or Readwise
Look elsewhere if
- Not for you if your highlights are nobody's business, as they're public unless you pay
- Pricey if you only want privacy, since Pro is $12.50 a month billed yearly, or $15 monthly
- Tight if you lean on the AI for free, with 3 basic YouTube summaries a day and 20 chat credits a month
- Watch out: Pro and Unlimited are marked recurring and non-refundable, and the 40% student discount covers yearly Pro only
- Skip it if you want a desktop app, as it's the web, an extension and phone apps
Pick Hypothesis if
- Fits if you read and mark up web pages alone or in a small private group
- Works for teachers who want students annotating readings inside the LMS
Look elsewhere if
- Skip it if you want paid prices on the page, as none are published for Bronze, Silver or Gold
- Tight if your school has more than 3,000 students, because the paid tiers cap seats at 1,000, 2,000 and 3,000 and larger needs a sales call
- Pricey if you need LMS integration or analytics, which are not on the free plan
- Not for you if you want a phone app, as only a browser extension and a bookmarklet are listed
How we grade them
| 2.4GPAGlaspFair | 3.0GPAHypothesisVery good | |
|---|---|---|
| Value for money | DPro is $12.50 a month billed yearly, nearly four times this category's $3.33 middle and well past the $7.99 where its dearest tenth starts, and keeping your highlights private needs it. Unlimited is $30 a month. Students get 40% off yearly Pro; subscriptions are marked non-refundable. | BThe free plan covers core annotation and private groups. Bronze, Silver and Gold are priced per student per year and no figure is shown, so a school can't compare the cost without asking. |
| Free plan and trial | CUnlimited highlights for free, with exports and the daily Notion sync, but the cap is an unusual one: every highlight is public unless you pay. The AI is rationed too, at 3 basic YouTube summaries a day and 20 chat credits a month. | AFree plan with annotation and private groups, and the listing shows no cap an individual would reach. |
| Features | BIt covers the whole job of collecting what you read: highlights with notes and tags on web pages, PDFs and YouTube transcripts that stay marked on the page, AI summaries, audio transcription, chat with a PDF, imports from Kindle, Readwise, Instapaper and Pocket, and four export formats. | CPage annotation, groups, tagging and a Chrome extension. But LMS integration, partner workshops, analytics and auto-grading are not on the free plan. |
| Ease of use | BNo store rating on record, but there's nothing to set up: install the extension and highlight on the page you're already reading. The phone apps add a reader view and a read-later library on top. | BNo rating on record. Add the extension or bookmarklet, sign up and start highlighting, with nothing else to set up. |
| Platforms and integrations | BWeb, a browser extension and iPhone and Android apps, with highlights flowing out to Notion, Obsidian, Readwise, Roam Research and Logseq and in from Kindle. No desktop app, which is what holds it to a B. | BWeb, a Chrome extension and a bookmarklet, with LMS links to Canvas, Blackboard, Moodle, D2L Brightspace and Sakai. No phone or desktop apps are listed. |
| Best for | highlighting articles and YouTube in the open | annotating web pages and readings in a class |

More comparisons
How this page was made
- The verdict at the top follows a fixed rule. When both tools are in the same category and either is in our top three for it, the verdict follows that ranking: the higher-placed tool is our pick. The top three weigh who each tool suits as well as its grades, so a pick can go against the GPA. Otherwise the page does not pick one and says which grades higher: the higher GPA first; on a tie, the one with a free plan, then the one that starts cheaper in dollars a month, counted the same way for both; if they are still level, what the choice depends on.
- The grades are our own, from each tool’s review or report card. The GPA is their average.
- Prices, plans and platforms come from each tool’s listing. The table above says where each price was read and when.
- The differences and the answers to the questions are worked out from those listings.
