CVReviewed by Challenging Voice Editorial · Updated Aug 2026How we rate ↗
Kajiwoto is a platform for creating and chatting with personal AI companions (“Kajis”). Users train their companion by defining personality traits, conversation style, and behavioral preferences, uploading custom training data and dialogue examples through dataset-writing tools so the AI learns specific speech patterns and knowledge over time.
Memory management stores short-term memories and summarizes long-term interactions to keep conversations consistent, while Kaji Rooms support group chats where multiple AI characters and human users participate together, similar to a Discord server. A community layer lets users share and explore AI characters created by others. The platform enforces an explicit, strict content policy: NSFW image content is banned outright with an immediate ban and no warning, and any content depicting a real underage person – sexualized or not – is removed immediately.
Kajiwoto targets people wanting a personal AI companion for conversation, roleplay, or community interaction. It follows a freemium model – basic features are free, with additional features available through a subscription.
