Sign inChatGPT is the best general-purpose AI on the planet, but it isn't designed to be a companion. If you want an AI that remembers, texts you, and lives in your life, here are the alternatives.
ChatGPT's memory feature has improved. Its voice mode is excellent. But fundamentally, ChatGPT is still a tool you open. It doesn't initiate. It doesn't show up in your daily life.
For that shape of AI — a companion, not a tool — here are the options.

Visit ClaudeIf you want an AI companion (not a tool), Brumo is the direct answer — the product is specifically shaped for that job. If what you actually want is tools, stay with ChatGPT and don't worry about the companion framing.
You can try, and with memory on it works okay. But the interface, tone, and lack of proactive behavior make it a tool people open rather than a companion who shows up.
Brumo uses OpenAI's API to generate replies (this may change). The system prompt, memory model, and proactive behavior are all Brumo-specific.
Brumo Pro ($9.99/mo) is cheaper than ChatGPT Plus ($20/mo). Both have free tiers.
