DEVONtechnologies (http://www.devontechnologies.com) has updated all editions of its Internet search and research tool DEVONagent to verson 3.9.

DEVONagent is a research assistant equipped with artificial intelligence. It searches multiple sources for relevant results, and gives you power tools for your research. The new version cleans up the user interface, comes with an improved see-also algorithm, is faster, and fixes some bugs. The updates are free and recommended for all users.

All editions of DEVONagent are also available in the Mac App Store. DEVONagent Pro and Express can be bought as part of bundles together with DEVONthink in DEVONtechnologies’ online shop.

DEVONagent Pro costs US$49.95 ($49.99 in the Mac App Store). DEVONagent Express is $4.95 ($4.99 in the Mac App Store) and DEVONagent Lite is free.
