Four ways Qiqqa helps you

Stored and secured

Are your PDFs littered across your desk or PC?

Qiqqa keeps all your PDFs secure and makes them instantly accessible and searchable across all your devices.

Automatic identification, tagging and categorization of your PDFs means you never have to go hunting for that missing paper again.

Annotation report

Do you remember where you made those important highlights?

Capture all your tags, comments, highlights and annotations while you read your PDFs inside Qiqqa, online at your workstation or offline on the go.

Then when you want to review what you have read, use powerful annotation reports so you never again forget those important snippets of information.

Deciding what to read

Qiqqa guides you through your literature by understanding your research niche. It then highlights the most specific and the most influential papers in that niche.

Qiqqa also lets you find what next to read by following citations, authors and keywords.

Writing up

Having trouble pulling your reading together while writing up?

Using Qiqqa's themes and annotation reports, you are literally presented with everything you should cite in each section of your paper.
