Which one is for you
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
Pick Pinboard if
- Fits if you want a text-based bookmark list with no ads or trackers, private by default if you like
- Works for people who want an API and an RSS feed for everything they save
Look elsewhere if
- Not for you if you want to try before paying, as there's no free plan or trial, only a seven-day refund
- Skip it if you want a native phone app, because it's a mobile website plus third-party apps
- Pricey if saved page copies are the point, as those and full-text search need the $39 account, not the $22 one
- Watch out: the archive crawler can't save paywalled pages, and the FAQ says YouTube and Twitter links aren't saved properly
- Watch out: the sign-up page says paying for several years is discounted but doesn't say by how much
How we grade them
| 3.0GPAHypothesisVery good | 2.2GPAPinboardFair | |
|---|---|---|
| Value for money | 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. | B$22 a year is $1.83 a month, inside the cheapest quarter for reading tools here, below the $2.42 line. The archival account, with a stored copy of every page and full-text search, is $39 a year. The sign-up page says paying for several years is steeply discounted, but won't say by how much. |
| Free plan and trial | AFree plan with annotation and private groups, and the listing shows no cap an individual would reach. | FNothing is free. There's no free plan and no free trial. You pay first, and the fee is refundable within seven days of signing up, which is a money-back window and not a trial. |
| Features | CPage annotation, groups, tagging and a Chrome extension. But LMS integration, partner workshops, analytics and auto-grading are not on the free plan. | CIt does one smaller job, bookmarking, and does the basics of it: tags, private bookmarks, read later, notes, tab sets and tag bundles. The gaps are in the listing: stored copies and full-text search need the $39 account, and even then the crawler skips paywalled pages, YouTube and Twitter. |
| Ease of use | BNo rating on record. Add the extension or bookmarklet, sign up and start highlighting, with nothing else to set up. | BNo store rating on record, since there's no app of its own. The listing shows a site with nothing to set up: sign up, add the bookmarklet or a browser extension, and save links. It's plain text and a tag box, so there's not much to learn. |
| Platforms and integrations | 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. | BA website with extensions for Safari, Chrome and Firefox, a full API modelled on Delicious and an RSS feed for every bookmark page, which third-party clients like Reeder use. No native mobile apps, though, so on a phone it's the mobile site or somebody else's app. |
| Best for | annotating web pages and readings in a class | plain, private bookmarks with no ads |

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.
