Mohit Agrawal (Princeton)
"#qiqqa is absolutely amazing. Who knew that thesis work could be this much fun?"
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."
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."
Nat

Ellie Carter-Silk

Preston
"You're awesome. This is awesome. Thanks so much. I have no one to blame but myself if this dissertation doesn't get written!"
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)

"I love this software. It not only automates tasks I used to do by hand (annotation report!!) but does things I didn't know I wanted to do (expedition). Thank you thank you thank you. --A grateful assistant professor"
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
"... love your software! I have sent your download link to all my Master/PhD fellow students and I know a few are already using it."

The program is so clever that I keep expecting to find a 'Create my PhD' button somewhere!"

Henriette

Kim
"Qiqqa has absolutely redefined my academic experience...thank you. I have shared it with many of my friends and acquaintances and they have started to share it with their friends. All the reports back have been positive. Well done and thanks again."
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!"

"...Ok, I've been using Qiqqa for about 3 days. I'm a doctoral student, in the field of Management Information Systems. I think Qiqqa is the BEST tool I've found for managing my PDF documents. 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. However, I have been rewarded for the long search I've made in finding Qiqqa..."

"I have been researching into and trying different references managers and Android capable reference managers, and Qiqqa by far and away is the best program out there. The software is well written, it's easy to use, and you can tell the people designing it actually know what the users are looking for."
