Private chats and up to four-way group rooms with customizable AI characters, plus scripted story scenes.
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.
Free plan allows limited chat rounds and one AI group room a month. Pro at $9.99/month removes the conversation cap and adds one custom character and five group rooms monthly. Max at $19.99/month raises those limits further and adds voice sample submission.
Use tool ↗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.
Watch out: The 18+ requirement at signup signals the character content can skew into mature territory.
