To conclude: you need tool which will generate keys (wif or hash) for some entry, right?
Do you want to use the list of your exact phrases or you want tool to automatically adjust your input (like change to uppercase or add numbers)?
I entry the string manually because I try different patterns as I try to remember, which I hope one is the right.
So I generate SHA256 manually, but it takes time to manually copy SHA256 and to generate WIF, one by one. I have got pain in my hands. And it is already pain.
