Is there an overall Spell/Grammar check in iOS?

I love, and own, everything Apple has put out (maybe I missed 1 or 2 devices(?))

Does anyone know about either a free, built in service, or at least a 1-Time, purchase fee,

I’m a severe TBI survivor, and little, helpful features like this, are one of the reasons I migrated every Digital Device I’ve purchased to Apple. (New photos appear on all devices (via cloud), passwords remembered on all devices, et al…)

I not can believe that Apple, in my mind, the ‘Everything for Anything’ system(s), does not also have an overall Spell Checker, and Grammar Check, built in.

After my research, all that I’ve been able to find in the App Store, has been Apps that appear to be worth using, are charged with some kind of subscription fees. So, when you stop paying to use these features, you lose it.

If you have any suggestions, or something you may have done, regarding this, and would be willing to share with me, I’d be deeply grateful)

Either way, thank you for any ideas you may share, or even your time spent just thinking about it. I also wish all to stay healthy)

Thank you,
