Top Sites Like Janitor AI in 2025
You can build a character thatโ€™s gentle, fiery, or downright feral โ€” then switch up the tone mid-conversation. The platform is surprisingly flexible with mood shifts, so if you start with pillow talk and end up deep in existential musings, it wonโ€™t flinch. NSFW is not only allowed โ€” itโ€™s expected. And unlike Character.AI, nothing gets censored behind awkward asterisks.
