Very easy to mark sites, and then create an outline is amazinf

Excellent!

Top notch tool for managing a lot of dissimilar information. Helps me track things and respond intelligently.

This is the web storage system that I have wanted for many years. Annotate webpages (like Edge wishes it could). Easy to use. Good system for adding tags, searching, organizing links. Access it from any browser. The add-on for Firefox seems to work perfectly. I would give it 6 stars if I could.

There are annoyances, such as excessively poups but it is interesting to try. I have all my bookmarks there, so I cant to change.

Wonderful library tool, practical, and great support

Amazing help with learning and organizing research!

I use Diigo since 2009, to have on hand all the bookmarks of pages I want to keep, for future revisions. Indisputably Diigo is the best.

Fantastic!!

Just awesome!

Excelente por donde lo mires.
Muy útil cuando necesitas sacar notas o apuntes de varios sitios web y no te interesa andar copiando o resumiendo dicha información.
Lo uso en el ámbito académico y profesional. Me da mucho resultado.
Sería muy positivo mejorar la integración con Safari de MAC OS, eso no funciona del todo bien.

I have used it for over 10 years and it is perfect for keeping and organising information on the web.

easy, fast, useful, clean. Great tool to organize informations.
