  • Platform Performance Issues
    Some users report occasional performance issues such as slow loading times or glitches during peak usage times, which can be frustrating during practice or contests.

    The best research tool

    Qiqqa is by far the strongest solution for research and managing pdf's. Zotero, named as a comparison is weak as it does not allow pdf;s to be loaded into its interface - you need to use a pdf reader, which defeats its whole purpose. With Qiqqa documents in a library can be searched together. It has excellent maps of your libraries. It is not prefect, having a few glitches, but still is the only one of its kind.

    ๐Ÿ‘ Pros:    Excellent ocr and search|Multiple libraries|Search within a library|Still supported
    ๐Ÿ‘Ž Cons:    Can be a bit glitchy|Can slow down of stop responding|Appears to need a lot of memory|Support can be a bit slow / technical
