Learn About AI Companions
Plain-language guides to help you understand how AI companions work, what risks to be aware of, and how to choose the right app for your needs.
- What Is an AI Companion?
AI companions are conversational applications powered by large language models that engage users in ongoing, personalised dialogue. Unlike traditional chatbots, they maintain a consistent persona and, in many cases, memory across sessions.
- Are AI Companions Safe?
Safety varies significantly across apps. Key risks include emotional over-reliance, exposure to adult content, and dark-pattern engagement mechanics. California SB 243 (in force since 2026-01-01) mandates specific safeguards for platforms targeting minors.
- How AI Companion Memory Works
AI companions combine two distinct memory mechanisms: the context window (everything visible to the model in a single conversation) and long-term memory (a separate database of stored facts retrieved at the start of each new session). Understanding the difference is key to evaluating any companion app.
