Congratulations on the launch!

Although 'synthesise' has broad meaning, I think organising the bookmarks this way helps to fetch our bookmarks when needed e.g. A need gap - 'I forget my web bookmarks quite often'[1] was posted on my problem validation platform which I think this tool can effectively address.

Did you have the intention of solving that problem when creating this tool? Then I would suggest improving the copy in the home page from 'Synthesise' to something on the lines of -

'Don't forget your bookmarks again, get them back when you need it'.

Also, an address bar integration which brings results from Klobie first could serve the purpose better IMO.
