Open GurujiAstroFAQ
Can I cite Hobnob in my paper?
Cite the underlying sources Hobnob returns, not Hobnob itself — same way you'd cite Google Scholar's results, not Google Scholar.
Is my data private?
Yes. Hobnob runs in Incognito mode by default — your queries are not used to train any AI model, and Pro/Business plans get zero ad tracking.
Do I need a credit card?
No. The free plan gives you unlimited AI search forever, no card required. Upgrade only when you want Pro Search, Deep Research or larger file uploads.
