Use tool ↗About TheirSide
TheirSide lets you have one-on-one conversations with fictional AI characters, run group chats with up to four AI characters at once, and step through scripted story scenes. You can upload reference material to help shape a character before chatting with it, and the service keeps conversation history with account-level memory controls. The free plan limits conversation volume and group rooms; paid tiers remove those caps and add custom character creation, more group rooms per month, and access to saved character memories.

Pros & cons of TheirSide
TheirSide covers a specific niche well: multi-character group roleplay, which most character-chat apps treat as an afterthought. The free tier is workable for casual use, but heavier users will hit conversation and group-room caps quickly and the product itself is still an early-stage, small-team effort.
Pros
- Supports up to four AI characters in one group chat, not just 1:1
- Lets you upload reference material to shape a custom character
- Story-scene mode gives structured scenarios instead of open-ended chat only
Cons
- Free plan caps conversation rounds and limits you to one group room a month
- Company behind the product discloses no country or legal entity
Best for
- People wanting group chats with multiple AI characters at once
- Fans of scripted story-scene roleplay
- Users who want to build a custom character from reference material
Not for
- Anyone under 18 — the service requires an 18+ age confirmation
- Users wanting a single, consistent long-term AI companion rather than multiple characters
Watch out: The 18+ requirement at signup signals the character content can skew into mature territory.
