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 Raindrop.io if
- Fits if you want one bookmark library on every browser, laptop and phone you own
- Works for people who share link collections or highlight passages in web pages, PDFs and EPUBs
Look elsewhere if
- Skip it if you want full-text search or saved copies of pages without paying, as both are Pro
- Not for you if you want a desktop app on Linux, since the download page lists macOS and Windows only
- Not for you if you'd rather not build collections and tags, because sorting is the work it asks of you
- Tight if you annotate a lot, as notes on highlights need Pro and each bookmark holds at most 100 highlights
- Watch out: Pro's $28 a year is before tax, and the AI assistant is still in beta
How we grade them
| 3.0GPAHypothesisVery good | 3.2GPARaindrop.ioVery good | |
|---|---|---|
| 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. | BPro is $28 a year, which is $2.33 a month, inside the cheapest quarter for reading tools here. For that you get full-text search, a saved copy of every page, reminders, daily backups, the AI assistant and 10 GB of uploads a month. |
| Free plan and trial | AFree plan with annotation and private groups, and the listing shows no cap an individual would reach. | AUnlimited bookmarks, collections, highlights and devices, with sharing and collaboration thrown in. The caps are 100 MB of file uploads a month and 100 highlights per bookmark, and most people will never touch either. Plenty stay free for years. |
| Features | CPage annotation, groups, tagging and a Chrome extension. But LMS integration, partner workshops, analytics and auto-grading are not on the free plan. | BIt covers the whole bookmarking job: collections, tags and filters, four views, highlights in web pages, PDFs and EPUBs, shared collections and public pages that need no sign-up. Pro adds full-text search including YouTube transcripts, a web archive and a beta AI assistant. |
| Ease of use | BNo rating on record. Add the extension or bookmarklet, sign up and start highlighting, with nothing else to set up. | C4.49 from 416 App Store ratings, which falls just under the 4.5 we want for a B, so middling it is. The work is yours as well: collections to build, tags to pick and a view to choose before the library looks like anything. |
| 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. | AThe full set: web, Mac, Windows, iPhone, Android and browser extensions, with an API and hooks into Zapier, IFTTT, Make, n8n, Notion and Readwise. The one gap is Linux, as the download page lists macOS and Windows only. |
| Best for | annotating web pages and readings in a class | all-round bookmarking on every device |

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.
