QuillBot

$10/mo

Built-in summarizer + citation generator
Free tier covers most use cases
Chrome + Word extensions

Trade-offs

Not a generative writer — purely transformation

Both are worth trying — most teams who switch land on whichever they evaluated second, because the first one set the comparison they didn't know they needed.
