FAQ

Is it free for students?

Yes — the free tier covers cited search, PDF chat (small files), and all writing tools.

Is it considered cheating?

Cited research and summarisation is no different from using Google Scholar. Generating final essay text without disclosure is plagiarism — don't do that.

Why does Hobnob AI show ads?

Because we keep search free and unlimited for everyone — no paywall, no credit card, 20 free searches a day. Running real-time web crawls, large language models, and TrustScore checks costs real money on every single query. A few non-intrusive ads are what let a tiny indie team keep the lights on so a student in Delhi, a researcher in Lagos, or a developer in São Paulo can use the same powerful AI search a Silicon Valley engineer uses — for free, forever. If ads bother you, upgrading to Starter, Pro, or Business removes them instantly and directly funds the people building this for you. Either way, you're helping keep open AI search alive.
