The verdict
Kajiwoto is built around a feature most AI-character platforms skip: you train your AI. Rather than loading a pre-made character card and chatting, you upload your own datasets — example responses, conversation samples, a personality description — and the platform fine-tunes how your AI responds over time using GPT as the base model. The trained persona can be kept private or published to Kajiwoto's public library for other users to chat with, which means you're interacting with AI personalities genuinely shaped by real people, not just generic template-swapped bots. The trade-off is investment: a good Kajiwoto companion takes real effort to build, and a poorly trained dataset produces mediocre results. NSFW content is "mild" — the platform allows some adult content but does not offer the full uncensored roleplay of dedicated NSFW hubs. Premium costs from around $8/mo. The interface looks dated compared to modern companion apps, and training can feel tedious if you just want to start chatting. Best for people who want to invest in a genuinely personalised AI — a wrong fit for users seeking out-of-the-box explicit content.
Best for hands-on tinkerers who want to train a genuinely personalised AI. For uncensored roleplay without training, Chub AI; for BYOAPI without building a dataset, Janitor AI.
