best AI tools for students (2026)
Hobnob AI is the free AI search built for studying — cited answers you can actually use in essays, instant summaries of dense PDFs, and unlimited questions even on the free plan.
What's broken today
- ×ChatGPT-3.5 free tier is outdated and capped.
- ×Most AI tutors don't show sources, so you can't cite them.
- ×Paid tools cost ₹1,500+/month — out of budget for most students.

Open Hobnob AIFAQ
Is it really free for students?
Yes — unlimited AI search, no card, forever. Upload PDFs and use every tool on the free plan.
Will my teacher detect AI?
Use Hobnob to research and summarise, then write in your own voice. Cited research is fair game; copy-pasting AI output rarely is.
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.
