I saw that your tool was querying blockchain.info, but it cannot guess
what derivation path was used and if it is a standard one what addresses
were used, and even if successful it works only for bitcoin (so maybe it
should just output the ~1500 possible phrases and/or xprv, and be
completely offline, this is still doable for people)

I forgot to mention that this can help also solving the "what if
something happens to me" case giving to the family the seed and the
parameter(s) for the derivation path, or an easy way to find it (better
than something like: remind this passphrase, take the sha256 of it, then
use some other stuff to find the encryption algo, take n bytes of the
hash, use it to decode my wallet or my seed... and then everybody
looking at you like crazy)
