How to choose
If what you want is a Japanese voice companion you can chat with as casually as a friend, Cotomo's voice experience is very smooth. If you want a world that keeps you company, remembers you, proactively gets things done, and leaves your data fully in your hands, Enclave is the better fit — its interface and AI replies support Japanese, and once self-hosted, your data lives only on your own machine.
FAQ
Does Enclave support multiple languages?
Yes. Enclave's interface comes in Simplified Chinese, English, Japanese, and Korean, and the AI residents can converse with you in the corresponding language too.Does Enclave's AI really have long-term memory?
Yes. Enclave uses a structured long-term memory system rather than a simple context window, so experts can still cite specific things you said months ago — not a vague "I think you mentioned that." Every memory is yours to view, edit, or delete at any time.Is my conversation data safe? Will it be used for training?
In self-hosted mode, your conversations live only on your own drive — they never leave your machine and are never used by any third party for training. The model layer can connect to cloud APIs like OpenAI and Anthropic, or be swapped for local Ollama / vLLM to run fully offline; you decide which kind of conversation goes to which model.
