Need vBSEO alternative for hot linking keywords

[J4CKT]

Is there an alternative to vBSEO out there that can hotlink keywords in threads? I'd like to upgrade to vBulletin5 but I'm stuck on vBulletin3 as I need this keyword hotlinking feature maintained to move forward. Any help would be appreciated. This is an example what the hot linked words look like in a thread.
