ChatGPTDiigo is built for a particular kind of person. You find a paper, you highlight the important paragraphs, you leave a sticky note explaining why it matters, and you file it in a list. Six months later that page is worth more than when you found it.
If that is genuinely you, Diigo is doing something real. Most people who say they work like that have about eleven annotated pages and four thousand unannotated saves. ContextBolt is built for the four thousand. It catches them, tags them and finds them again without you having marked anything.
The free tier runs out sooner than you think
This is worth stating plainly because it is easy to miss. Diigo’s free plan is 500 bookmarks and 100 highlights, and those are lifetime totals rather than monthly allowances. It also carries ads.
Five hundred sounds like a lot until you count what a year of ordinary saving looks like. Then you are choosing between deleting old material and paying $40 a year for Standard or $59 for Professional, both annual only.
ContextBolt Basic is free up to 150 bookmarks, and Pro at $6 a month removes the cap. The bookmark manager pricing guide sets both against the rest of the category.
Annotating is a decision you make at the wrong moment
Marking up a page requires you to know, right then, what will matter later. Sometimes you do. Usually you are three tabs deep in something else and you save it because it looked useful.
ContextBolt is built for that second case. Save the page in one click and it keeps the article text. AI tags it by topic as it arrives. Later you search “leading questions” and get the piece back whether or not past-you highlighted the relevant paragraph.
The same applies to everything you save on X, Reddit and LinkedIn. Those arrive on their own, because ContextBolt captures the save as you make it. Diigo needs each one added by hand, which is the step people stop doing by week three.
Then ask your agent for it
On Pro, the library is exposed over MCP, so Claude or Codex can search it while you are writing the thing you needed it for. Ask for what you saved about recruiting interview participants and it comes back with the sources, by meaning rather than by keyword.
Unless your agent has its own route into Diigo, getting Diigo material into it means copying and pasting.
Where Diigo still fits
Diigo is for marking up a small set of documents you work through carefully, and for group research projects where several people annotate the same material. Highlights, sticky notes, PDF annotation, the outliner and shared groups are all real, and they are all Diigo’s job.
That is not the job most saving is. ContextBolt is not a markup tool and runs in desktop Chrome, and it is built for the wide net, every page and every social save, tagged on arrival and findable without a single highlight. Keep Diigo for the deep work if you do it, and let ContextBolt catch everything else, starting free on your next save.
The test
Save the way you already save for one week, across web pages and your social accounts, and annotate nothing.
Then search for something you half-remember. That is the workflow most saving actually is, and it is the one ContextBolt is built for. Start free with ContextBolt Bookmarks.
