By The real trade-off here is simple. Diigo is a research notebook with annotations, highlights, and an outliner. not24get.me is a modern bookmark manager that saves links with context and finds them again fast. If your work lives in highlighted paragraphs and sticky notes, Diigo earned its two decades. If your work is collecting links, organizing them, and sharing them with a team, a lighter and newer tool fits better.
This page compares both on the jobs that matter: capturing, finding, sharing, and keeping a research library over time. Prices and limits below are checked against the live Diigo site.
The 60-second version
Diigo launched in 2006 and still does things few tools attempt. Highlights in multiple colors. Sticky notes on any page. Archived copies of what you saved. An outliner for building documents from your research. Group libraries let a whole team annotate the same sources. The free plan is ad-supported and caps you at 1,000 bookmarks and 200 highlights. PDF annotation, full-text search, and bigger groups sit behind paid plans at $40 or $59 per year. The interface shows its age, and that is the honest price of the feature depth. Pick Diigo if annotation is the core of your research workflow, not an occasional extra.
not24get.me is a bookmark manager built around one loop: save with context, find with search, share with your team. You save from the browser extension with a note and tags while the page is open. Paid plans search the full text of archived pages. Shared folders and workspaces hand a team the same structure you built. The free plan is unlimited bookmarks with two workspaces. Pro is 1 EUR per month. Pick not24get.me if you want a fast, modern home for research links instead of a full annotation suite.
Where they differ
Capturing what you find
Diigo captures more than a URL. Its extensions for Chrome, Firefox, and Safari let you bookmark a page, highlight passages in several colors, attach sticky notes, and keep a cached copy. That cached copy matters when a source disappears. Researchers who read closely get real value from this, because the annotation lives next to the link it came from.
not24get.me captures less per page, on purpose. You save the link with a one-line note and a tag or two while the page is open. The note carries the context a highlight would. The habit is faster to keep, which is why it survives past the first week. What you give up is in-page markup. What you keep is a library you actually maintain.
Finding it again later
Diigo's search is strong on paid plans. Standard and Professional search the full text of your cached pages, not just titles and tags. The free plan searches meta info only. For a library of thousands of annotated sources, full-text search is the feature that makes the archive usable.
not24get.me follows the same logic at a lower price. Every plan searches your notes and tags. Pro and Team search the full text of archived pages, so the words you remember from the article lead back to the link. Previews inside the hub let you confirm a result without opening ten tabs, and link checks flag broken URLs before you cite them.
Working with others
Credit where it is due: Diigo's group libraries are genuinely useful for research teams. A group can pool bookmarks around a topic, and members can highlight and comment on the same shared sources. For a literature review or a classroom, that shared annotation layer is the product. The free plan allows one private group with three members. Larger groups require a paid plan, and the Teacher plan gives educators a dedicated free tier.
not24get.me covers the same collaborative research workflow without the annotation layer. You share a folder or a workspace, and recipients get your notes, tags, and structure exactly as you built them. Nobody reconstructs anything. For teams whose research output is a set of links with context, not a marked-up PDF, this is the simpler path. Team plans cost 3 EUR per seat per month for two to seven seats.
Keeping it long-term
Diigo's longevity is a point in its favor. It has survived since 2006 while dozens of similar services shut down, and its own premium page says as much. Cached pages on paid plans protect against link rot. The trade-offs are the dated interface, ads on the free plan, and a pricing structure where PDF highlighting and full-text search require a subscription.
not24get.me is the younger product, so the calculation is different. The paid plans are priced low enough that keeping the library costs less than a coffee per month. Link checks run in the background so dead links surface early. And the API on every plan, including free, means your data is never trapped: 1,000 calls per day on Free, 50,000 per period on Pro.
If you are moving from Diigo
Moving the links is easy. Moving the annotations is not, so set expectations before you start.
- Export your Diigo library. Diigo offers an export of your bookmarks as an HTML file from the library settings, and a CSV export for spreadsheet tools. Group libraries can be exported the same way by a member with access.
- Create a free not24get.me account and install the browser extension.
- Import the bookmarks into a folder. not24get.me imports browser bookmark files, so the standard HTML export drops in cleanly.
- Re-save your most active sources with a fresh note and tags. For the twenty pages you touch every week, two minutes of re-saving beats a bulk import of stale context.
- Recreate shared libraries as shared folders or team workspaces, then invite the group.
What does not transfer: highlights, sticky notes, and outliner documents. Diigo's annotation data does not map onto a bookmark manager, and no import will carry it cleanly. If those annotations are your research record, export or archive them separately before you cancel. If they were occasional extras, the note you write at save time replaces them.

FAQ
What is Diigo?
Diigo is a social bookmarking and research tool launched in 2006. It combines bookmarking with highlights, sticky notes, archived page copies, an outliner, and group libraries for collaborative research. It remains one of the oldest tools in the category still running.
Is Diigo free?
Yes, with limits. The free plan is ad-supported and caps you at 1,000 bookmarks and notes and 200 highlights. PDF annotation, full-text search, multi-color highlights, and larger group libraries require Standard at $40 per year or Professional at $59 per year. Educators can apply for a free Teacher plan.
What is the best Diigo alternative?
It depends on the job. If you annotate PDFs and web pages every day, Diigo's annotation depth is hard to replace and staying may be the right call. If your real need is saving links with context, finding them again with search, and sharing them with a team, not24get.me is a modern Diigo alternative that covers that workflow for 1 EUR per month. Other options in this series include Raindrop.io and Karakeep.
Does not24get.me support annotations and highlighting?
No. not24get.me does not offer page highlighting, sticky notes, or PDF annotation. Instead you save each link with a short note and tags, preview the page inside the hub, and on paid plans search the full text of archived pages. The note replaces the highlight for most recall jobs. If in-page markup is essential to your work, that is a real reason to stay with Diigo.
If the annotation suite is more than you use, a modern bookmark manager is the calmer home for your research links. Compare not24get.me with Matter, Karakeep, or Raindrop.io, check the pricing, and start free.
