I stick with 'Seventh Sanctum' for the bulk of my initial character concepting. Its generators are varied enough to kickstart a backstory—you get a name, a suggested class, a quirk, all in one click. It doesn't produce publish-ready material, but that's not the point; it breaks my own repetitive naming habits.
For more linguistic coherence, especially with worldbuilding, I'll then take a promising root from that list and feed it into 'Fantasy Name Generators' to flesh out surnames and place names that sound like they're from the same culture. The real work begins after generation—tweaking syllables until the name feels like it belongs to the person in my head, not just a random assortment of apostrophes and consonants.
Honestly, the best results come from using these tools as a collaborative prompt, not a final authority.
