PersonaChat.gg — characters with live expressions, long-term memory, and Rooms with 3–4 characters (solo dev, free tier)
Solo dev, so this is self-promo. PersonaChat.gg is interactive fiction: characters' sprites can change expression with every reply, they remember what happened weeks ago, and they can text you between chats. Rooms put 3–4 characters in one scene. SillyTavern cards and lorebooks import. 10 messages work without an account. New characters and new outfits for existing ones land every week.

NSFW: SFW by default; signed-in adults can opt in to 18+ after a self-attested date-of-birth check, and it's per character (On / Auto / Off)
Image gen: none (you upload art)
Legal: personachat.gg/legal/terms · personachat.gg/legal/privacy · you own what you create
Retention: chats live in your browser; if you turn on sync (publishing a character does too), the server copy stays until you delete your account; server logs only as long as needed
Models: Ling 3.0 Flash via OpenRouter on every plan (Llama 3.3 70B as the backup), separate models for 18+ chats, or bring your own OpenRouter key; each reply gets the last 16 lines plus the 6 most relevant memories
Pricing: free = unlimited messages, 50 memories per character; paid = Torch $5, Lantern $10, Aurora $20/mo (300 / 600 / 1,500 memories, longer scrollback, watch-together)
Access: web, phone or desktop browser (no app)
Updates: new characters and new outfits every week
Experience: IT student; PersonaChat is the biggest thing I've built. Live since September with a small Discord of playtesters
Testing: strict TypeScript checks, ~75 automated checks before every deploy, a memory test suite, Discord playtesters
Security: Discord/Google sign-in only (no passwords stored), hashed session tokens, Stripe handles cards, chats stay in your browser unless you turn on sync; messages that sexualize minors are blocked server-side and flagged to me; every character, message, room line and text can be reported
