Scored by a Toolio reviewer after real useOur verdict
ZhiNang.ai lets you summon a ChatGPT-powered assistant from any web page through its browser extension, without needing your own API key. Each message spends a virtual GPTCoin that you earn through registration, invites and daily logins, or buy outright, and the site's custom brain tank personas let the community build and share their own assistants. It works well for browsing and trying different community-made assistants for free, but anyone chatting heavily will burn through free coins and need to pay or grind daily logins to keep going.

✕Where it falls short
Pay-per-message currencyEvery chat spends a coin balance, so messaging is not truly unlimited.
Earning coins takes effortFree coins require daily logins, invites or registration, not automatic refills.
Plugin lags the siteThe browser plugin only gets features after the main website, not at the same time.
