A plain-English guide to using Gemini's free tier for research — from summarising PDFs to grounded web search, with prompts you can copy today.


NotebookLM turns your own notes and textbooks into a personal AI tutor that only answers from your sources — and even makes an audio recap. Here's how.

From grounded study notes to citation-backed research, these free AI tools genuinely help with exams — used the right way. A student's practical toolkit.

Both are excellent and both have free tiers. Here's an honest, task-by-task breakdown of when to reach for ChatGPT and when Claude wins.
Most people open an AI chatbot, ask one vague question, get a bland answer, and conclude AI "isn't that useful." The truth is that Google Gemini is one of the most capable research tools available for free — you just have to use it like a research assistant, not a search box.
This guide shows you exactly how, using only the free tier (Gemini 2.0 Flash).
Gemini has three things that make it genuinely good for everyday research:
The single biggest upgrade to your results: paste the source material first, then ask your question. If you have a 20-page tender document, paste it in, then ask "What are the eligibility criteria and submission deadline?"
For current facts — fees, rules, prices, news — add a line like:
Search the web and give me current information with sources.
This activates Gemini's live search grounding so you aren't relying on stale data.
Vague questions get vague answers. Tell Gemini the shape you want:
Reply in a table with columns: Topic | Key Point | Action Needed.
AI can still get facts wrong. For research that matters, cross-check with a citation-first tool like Perplexity and confirm important numbers against the original source. Treat Gemini as a brilliant first draft, not the final word.
Used like a research box, Gemini is mediocre. Used like a research assistant — context first, structured output, web grounding on — it does an hour of work in minutes, for free. Want a structured path through Gemini and the rest of the free AI toolkit? Explore the CertifAI programme.
