Aether vs JanitorAI
JanitorAI has the characters. Aether has the model quality.
TL;DR
JanitorAI is the go-to Character.AI alternative with a NSFW toggle and community characters. But the model quality is noticeably weaker, context is limited, and the free tier is often slow or unavailable. Aether has frontier-grade writing, 1M token context, and rock-solid reliability — the tradeoff is building your own characters via Custom Assistants instead of browsing a marketplace.
