i-net Doqua is an Eclipse plug-in that helps documentation writers and developers to keep track of inconsistencies between style guides and the actual documentation. The system integrates into the Eclipse IDE and introduces a new perspective and several views. Since i-net Doqua uses standard JUnit testcases to check the documentation, you can trigger checks using Hudson or similar Ant based systems.
CI-Eye is a powerful continuous integration build radiator requiring no installation and almost no set-up. CI-Eye talks to many different CI servers through their REST APIs (so no plug-ins are required). Currently, support is offered for Hudson, Jenkins, and TeamCity. CI-Eye runs as a standalone Web application.
