  • Charlotte Munoz
    "@laurapasquini @qiqqa I've got Mac friends buying pcs or running in parallels JUST for #qiqqa. Makes sharing papers for classes a breeze, 2."
  • Hyod
    "I personally want to thank you for coming up with this mind-blowing idea. I just started my PhD a little over two months ago and my library is a mess. I've used Excel to manage my articles and i thought it was cool enough.  Your Qiqqa made my Excel idea look like a toddler's painting next to Michelangelo's."
  • E.M. Matthews
    "I think Qiqqa rocks - Thanks to Qiqqa I was able to organize and search through hundreds of PDF journals and extract the information I needed to complete my PhD! I wish I had stumbled upon it sooner, but now that I have, and found success, I'll be sharing Qiqq with everyone I come in contact with."
  • Kleber Neves
    "Awesome piece of software. I'm recommending it to everyone. The best thing is how it took me only a couple hours to set up, get the metadata and organize all my PDFs, with little to no effort on my part. Amazing. I'm still finding out new features I like."
  • E.M. Matthews
    "I think Qiqqa rocks - Thanks to Qiqqa I was able to organize and search through hundreds of PDF journals and extract the information I needed to complete my PhD!"
  • Matthew Hicks
    "I have over 600 articles index and searchable. I could not have done this with our QiQQA. Keep up the good work. QIQQA saved me this summer."
  • Bill A.
    "Great software! Been using it since January 2011! Been very helpful with my research."
  • Mete Akcaoglu (Michigan State)
    "awesome FREE pdf reader/annotator! There is an annotation generator, built-in!!!"
  • Jill W
    "I love it. LOVE IT! This is making my lit review so, so much easier. It's intuitive--like it was built by people who actually do research. Bravo. I'm not one to push product recommendations, but I'm going to enthusiastically recommend Qiqqa to the other research students I know."
  • RazorShultzor
    "Qiqqa is an incredible piece of software. I am SO glad I found it. It does everything better than all the big qualitative research programs like NVivo and Atlas"
  • rschuet
    "Just bought my 1-year premium membership to Qiqqa. Had to support this program, because it pretty much rocks. All the organization tools for my PDF library are absolutely amazing."
  • Elzbieta Jaskulska

  • Jarl
    "Qiqqa is a fantastic tool and I will use it more and gather constructive feedback to share with you when I have it. What I can already say is that I've got a large collection of PDFs that just sat on a server for a long time until I found Qiqqa and was able to make heads and tails of them. Fantastic tool, fantastic work!"
  • luis.manso
    "I would like to thank the people from Qiqqa for their support. They sent me a patched version that fixed the problem in less than 24h. The day I can autonomously work with my Android tablet (which would involve adding documents and highlighting) I would get a Qiqqa tatoo (just kidding :P). Good job! Thank you!"
  • Malavikat
    "I found qiqqa just a month or so before I wrote my comprehensive/qualifying exams for my PhD. The ability to tag/search/annotate and organize all of my documents went a long, long way to helping me stay on top of papers as I wrote them. After a bit of a break I'm now back to work on my research proposal and can't wait to dive head first into all of the updates you've made in my few weeks off. :) Thanks for developing fantastic software and for being so responsive to your users' requests."
  • University Ninja (Website)

  • ga385
    "I love Qiqqa. I've spent the last few days installing and playing around with Endnote x4 and x5, Mendeley, and Qiqqa. While I have not tried actually writing and citing yet, all the other features make Qiqqa a stand out tool. The passion behind the product is obvious and while I know it is still a work-in-progress, it is setting the standard."
  • Valerie

  • Jess
    "Qiqqa is awesome. I spent a bit of time trying to decide which reference software to use before beginning my phd this fall. I had tried citeulike for my master's dissertation and explored endnote, mendeley and others, but none of them did everything I wanted. Qiqqa is far superior to anything else out there. Thank you so much for making it!"

It provides excellent organization, tagging, and annotation features. A friend of mine said that it is just procrastinating to go looking for the 'perfect' tool rather than just diving in.
