Many people here talk about Overleaf as if it was the 'dumb' editor without any of these capabilities. It had them for some time via Writefull integration (https://www.writefull.com/writefull-for-overleaf). Who's going to win will probably be decided by brand recognition with Overleaf having a better starting position in this field, but money obviously being on OAI's side. With some of Writefull's features being dependent on ChatGPT's API, it's clear they are set to be priced-out unless they do something smart.
