We will offer browser extensionswhich individuals can optionally install. These extensions will retain (if desired) local query data and also sync data down from our servers that can expedite queries.
One of the salient examples of how this could expedite searches is by using past searches. We can cache the results of past searches on your local computer and when you make the same query again return the results without unnecessary network traffic. In addition, we can provide a regular checking mechanism that updates the results with the latest results on a regular basis to ensure your local results are not inferior to those on our servers.
In addition, these extensions will (optionally) provide advanced bookmarking, highlighting, annotation, and save for later functionality.
If users are willing to share some or all of this data with us we believe it also can help us improve our search results.
All extensions would have a strong emphasis on ensuring the security of user data and of using the minimum permissions possible to run.
