Which should you pick?

If your top criterion is price: Grammarly. If you care most about brand voice training that actually holds across long runs, pick Jasper. If works in every text field across every app matters more to you, Grammarly is the better fit.

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.
