Character.AI is built for personas. AiMixup is built to ship work.

Character.AI is a roleplay and companion-chat platform — since late 2025 it has also restricted open-ended conversations for under-18 accounts, replacing them with a limited, age-verified experience. AiMixup solves a different problem: a multi-model workspace where teams chat, plan and ship real work.
