Glossary FAQ
What does NSFW mean in AI chat?
Not safe for work: sexual or explicit content; SFW is the opposite. Lazys is 18+, and its Community Guidelines set the limits.
What is the difference between a persona and a character?
The character is who she is: name, age and look. The persona is how she plays it: her voice, background and the way she treats you.
What does token pricing mean in AI girlfriend apps?
Paying per message or image from a bought balance. Lazys chat is free; coins pay for chat photos (1 coin), clips (3), Short Drama episodes after the first (2), tips (1–50) and private packs (5, or with Premium).
What does persona memory mean?
What a character keeps about you between messages, such as your name or a running joke. On Lazys each thread is saved and reopens where you left it, and she keeps a summary of it (a longer one with Premium).
