I feel like it's an extremely useful feature, but currently it is out of sight and requires the following knowledge:
- I need to know proofreading exists in Discourse
- I need to know the sparkle represents AI
- I need to know it is an AI feature
New and infrequent users - who are also most likely to benefit from proofreading - are unlikely to know all three of the above pre-requisites.
I wonder if it makes sense to put proofread specifically next to the new topic button:
I would even consider going one further and add a third button "suggest title".
Discuss this on our forum.
