Anyone can make one clean save look good in a demo. The honest test is dumping in a decade of bookmarks and seeing whether the thing still works.
I build Markwise, so I am biased. It takes a bulk import as a background job: each URL fetched, text extracted, summarised, tagged, indexed. Some fraction fail because a site is gone, slow, or blocks scraping. Dead links are a certainty at that age.
The import checkpoints. If it fails partway, it resumes instead of starting over or silently duplicating everything. That is the engineering I am willing to stand behind.
The unsolved half is archaeology. Some of it is worth keeping. A lot of it is a 2019 tab I never opened. I do not have a good answer for helping you decide which is which.
If you moved bookmark tools recently: did you import everything, hand-pick, or declare bankruptcy and start empty?
Markwise is at markwise.app. Free tier. Chrome extension, web app, iOS.
The archaeology problem is probably the more interesting challenge than the import itself. Getting years of bookmarks into a searchable system is useful, but helping people decide what is actually worth keeping could be what makes the product genuinely valuable.
Agreed, and I say that as someone biased since I build Markwise. Import is a solved, boring problem. Archaeology is not solved: a big chunk of an old export is dead links, and for the rest I have no honest signal for "worth keeping" beyond what you saved and never opened again. Right now the most useful thing I can do is show you that, and let you delete. Automatic judgement of value is the part I have not cracked.
