About Grammarly
Authorship expands into Blackboard, extending the one product built for the AI-in-classroom problem.
Grammarly's feed is mostly evergreen writing-advice content - salary negotiation emails, follow-ups, email blasts - with occasional product and research posts mixed in. The product thread that matters runs through Grammarly Authorship, which records how a piece of writing was produced so instructors can see what a student actually did. Authorship launched in beta inside Google Docs and now reaches Blackboard, putting it inside a major LMS rather than a document editor.
