Co-ment is a Web service for submitting texts to allow comments and annotations. You can upload or create texts on-line, invite designated users to comment on them, and if relevant, accordingly revise the text. Collaborative writing using this type of format enables better revision processes.

The key features of co-ment are:
- interface to create, navigate and process marginal annotations
- simple workspace where you can manage user rights and versions of texts
- can be used for producing texts together, in particular when a few drafters seek feedback from a larger group of commentators
- annotating existing texts, for instance as part of educational, scholarly or legal analysis processes

I had been using the earlier version at http://www.co-ment.com for classes and I have not switched over to the new service. co-ment has gained some traction for text-centered applications in education and in humanities research and in the legislative and legal domains.

There are actually 3 versions:

1. For an immediate work on a single text (without quantitative limitations) through the https://lite.co-ment.com free-of-charge service
2. With a specific workspace where texts and users can be managed in a perennial manner, through the co-ment PRO service at http://www.co-ment.com
3. By installing your own co-ment server thanks to the COMT free software (AGPLv3), available from the community site at http://www.co-ment.org

Thanks to an open API, co-ment functionality can now be integrated into a CMS such as the Drupal client for making the annotation functionality of co-ment directly and transparently available.
