Pros

+ 20 million stories across 100+ genres from 440,000 creators, the library dwarfs every competitor
+ Kink intensity sliders let you calibrate exactly how far each scene goes
+ Character builder with 15,000+ user-created characters available to remix or use directly
+ Audio conversion handles stories up to 17,000 words for listening sessions

Cons

- Premium starts at $12.69/month, pricier than SmutWriter's $7 casual tier
- Free tier daily generation is restrictive, you'll hit the wall within a few stories

Pros

+ Group chats run multiple characters in one room, closer to Character.AI's scene format than another single-thread companion, built for scenarios that would get shut down over there
+ Persona system lets you switch how you present without wiping what each Solmate remembers about you
+ Conversation memory persists across sessions so characters pick up where you left off instead of cold-starting every reopen
+ Openly built for adult roleplay from the store listing to the character library, no wholesome-companion veneer to see through

Cons

- Ads, coin packs, and subscriptions all stacked at once, with ad prompts that cut into scenes right when momentum builds
- Phone only, no browser version or desktop client, so anyone who prefers a real keyboard is stuck thumb-typing
- Rougher on some Android devices than apps with bigger install bases, input bugs and layout glitches still surface
