The basic citeKeeper product is free, and we don't expect that to change. If you are a free user, enjoy the system. We only ask that you recommend it to others if you find it useful. We also welcome your suggestions as to how citeKeeper could be more useful to you.
citeKeepr contains additional features for law firms. Currently, these firm-specific features are also free. We expect to begin charging an annual subscription fee for the firm-specific features in Q2 2015.
