AI Companions

Continuity of character separates this category from ordinary chat. AI Companions hold a persona steady across sessions, retain details shared weeks earlier, and answer in a register the user selects: friendly, mentor-like, playful within stated limits, or the voice of an invented character. Typical features include an editable backstory, memory the user can inspect and correct, voice calls with synthesized speech, generated portraits, and roleplay modes used for fiction drafting or language practice.

People turn to them for low-stakes conversation at odd hours, for rehearsing a difficult exchange before having it, and for practicing a second language without embarrassment. Novelists and game writers test dialogue this way. Apps vary in how durable and editable memory is, how consistent a persona stays after a model change, how strict moderation is, whether history can be exported, and how much intimate conversation sits on a vendor's servers.

Read the retention and deletion policy before sharing anything personal, and check whether history can be exported if the service closes. Look at how the app responds to a user in distress; companion AI tools are no substitute for professional care, and responsible ones say so and point toward help. Known problems include memory that contradicts itself, persona drift and abrupt content-policy changes. Pricing runs to free tiers with message caps, monthly subscriptions, or credits spent on messages, images and voice minutes.
