A Spell Checker

I have a spell checker
It came with my PC
It plane lee marks four my revue
Miss steaks aye can knot see

Eye ran this poem threw it
Your sure real glad two no
Its very polished in its own weigh
My chequer tolled me sew

A cheek or is a blessing
It freeze yew lodes of thyme
It helps me right awl stiles two reed
And aides me when aye rime

Now spilling does not phase me
It does knot bring a tier
My pay purrs awl due glad den
With wrapped words fare as hear

To rite with care is quite a feet
Of witch won should be proud
And wee mussed dew the best wee can
Sew flaws are knot aloud

So ewe can sea why aye dew prays
Such soft wear four pea seas
And why eye brake in two averse
Buy righting want to please
