Is there any Grammar-check module or Gui-Extension available? CME has only spell check option. One of our client asked for it. Has anybody integrated some third-party grammar check module?
Good question. It's great to see clients trying to improve their content & editorial processes.
Acrolinx (http://www.acrolinx.com/) is 'content optimisation software' that provides the following four features:
Spell checking (incl. custom / domain specific dictionaries)
Phrase / terminology checking
Checking against custom (content) style guides
I've never used it (I did chat to one of their sales team at SDL Innovate for quite a while), but they are an SDL technology partner, so there should be a direct/easy integration with the Content Management Explorer (CME) available.
They are also technology partners with other big CMS & Document Management Systems (incl. Sharepoint), so your client may be able to use Acrolinx across more than just their Tridion content.
I think that they also do a SAAS version, but there may be some limitations (as well as benefits) to this.
SDL SafeGuard is a tool for quality control - http://www.sdl.com/products/safeguard/
I am not 100% sure if it does grammar, but I know it does spelling.
You can also setup custom compliance rules, for example
coca a cola must fail the compliance test as it should always appear
