The honest brief
Nomi
Layered short/medium/long-term memory plus group chat with multiple companions at once — depth most companion apps lack.
- One sub covers multiple companions
- Group chat with several at once
- Unlimited voice calls on paid tiers
- Daily AI image generation on paid tiers
- Smaller community than Character.AI
- Best features behind paywall
- Companion realism still uneven
SillyTavern
The most configurable roleplay frontend — lorebooks, extensions, and any backend, where rivals lock you to one model.
- Free, open-source (AGPL-3.0), no paid tier
- Deep prompt control, lorebooks, group chats
- Connects to many backends (cloud or local)
- Portable PNG character cards
- Steep learning curve; DIY hosting
- Pure frontend — you supply the model/backend
- Dense panels are awkward on mobile
- No built-in moderation or safety rails
