There is software that allows you to brute-force this kind of manipulation. I've never tried it, for fear of a virus, but even if they are surely "safe", is it possible that a software finds my seed?
It depends on how much you remember from your seed. If only few words are missing (like 3 or 4 words) and you know their exact position, then recovering the seed using a good tool is possible. The more you remember the faster the tool will find your seed. Once it finds it, you can use it to recover your wallet and you will have full access to your coins.
I've seen many reputable members recommending
BTCRecover, so I believe it's safe.
