Please keep in mind that even though both Grammarly and CELUM may offer a reliable array of features every service may be created for a different company size. If you are comparing features you may want to pay attention to a business size they are meant for. Certain functionalities may scale up efficiently for large enterprises but if you run a small or mid-sized business it’s frequently more sensible to stay away from paying for customized features that you may never actually use.
