AI tools can save students a serious amount of time, but most comparisons assume you're happy to pay $20 a month for every tool. This one doesn't. Almost everything listed here is free, and the few that have paid plans work well enough on the free tier for student use.
These are tools that Indian students are actually using, not just tools that look good on a list.
ChatGPT (free tier)
ChatGPT's free plan gives you access to GPT-4o, which is one of the best general-purpose AI models available. The free tier has usage limits, and during busy hours you might get switched to an older model, but for most student tasks it's fine.
What it's useful for: explaining concepts you didn't fully understand in class, helping you structure an essay or report, summarizing long reading material, drafting emails to professors, and working through problems step by step.
One thing worth knowing: ChatGPT can confidently give you wrong information, especially on factual questions. Don't use it as your only source for anything you're going to submit. Use it to understand, then verify.
Free plan: GPT-4o with daily limits. No credit card required.
Google Gemini (free)
Gemini is Google's AI assistant and it's fully free. What makes it worth using alongside ChatGPT is Google integration. If you're on Google Docs, Gmail, or Google Drive, Gemini works inside those tools. Summarizing a document in Drive, drafting an email reply, generating an outline inside Docs. It's convenient when you're already in the Google ecosystem.
The AI quality is comparable to ChatGPT for most tasks. Some students prefer one, some prefer the other. Worth trying both and seeing which one's responses feel more useful to you.
Claude (free tier)
Claude is made by Anthropic and is worth knowing about even though it's less talked about than ChatGPT in India right now.
Claude's free tier is genuinely good. The context window (how much text it can process at once) is large, which means you can paste a full research paper or a long document and ask it to summarize or analyze the whole thing without it cutting off. For students who need to process long academic reading material, this is useful.
Claude also tends to write in a more natural, less robotic style than ChatGPT. If you're drafting something you want to sound like a person wrote it, Claude's output often needs less editing.
Perplexity AI (free)
Perplexity is different from the others. It's an AI search engine. Instead of just generating an answer from its training data, it searches the web and gives you an answer with numbered citations you can actually click and verify.
For research and fact-checking, this is significantly more useful than using ChatGPT or Gemini. When you're writing a paper and need to back up a claim, Perplexity tells you where the information came from. You still need to read the source and verify it yourself, but it cuts down the time spent searching.
The free plan covers most use cases. The paid plan gives you access to more powerful models and more searches per day.
GitHub Copilot (free for students)
This is the most valuable thing on this list for engineering students, and a surprising number of people don't know about it.
GitHub runs a Student Developer Pack for verified students. If your college has given you an institutional email address (ending in .ac.in or your institution's domain), you can often verify your student status for free. Once verified, you get GitHub Copilot completely free, plus a large number of other paid developer tools at no cost.
GitHub Copilot is an AI coding assistant that works inside VS Code and other editors. It suggests code as you type, completes functions based on comments you write, and helps you understand code you're reading. For students learning to code, having an AI suggest the next line while you're working through a problem is actually a good way to learn patterns.
Without the Student Pack, Copilot costs $10/month. Free for students is a genuinely good deal worth taking advantage of.
To apply: go to education.github.com and click "Get student benefits." You'll need to verify with a college email or student ID.
Grammarly (free tier)
Grammarly's free plan catches spelling errors, basic grammar mistakes, and suggests clearer phrasing. For students writing in English as a second language, or for anyone who writes quickly and makes small errors, it's useful.
The free plan doesn't cover everything (style suggestions and tone detection are behind the paid plan), but it's enough for polishing assignments, emails, and reports before submitting.
It works as a browser extension inside Google Docs, Gmail, and most places you type online.
Canva (free tier)
Canva's free plan is generous for students. Templates for presentations, posters, infographics, and social media posts. Most of the editing features work on the free plan.
For presentations specifically, Canva is worth considering as an alternative to PowerPoint or Google Slides. The templates look better out of the box, and making something that looks professional takes less effort.
The AI features on Canva (like Magic Write for generating text or background removal) are partially available on the free plan with a limited number of uses per month.
Notion (free for personal use)
Notion's free plan is fully usable for individual students. You can create a note-taking system, organize your course materials, build a study schedule, and keep a project tracker all in one place.
The AI features inside Notion (Notion AI) have a limited free trial, but the core tool without AI is free indefinitely.
Many students use Notion as their one place for everything: lecture notes, assignment tracking, exam preparation schedules, and project documentation. Once you get used to how it works, it's hard to go back to scattered notes.
A practical setup for most students
You don't need all of these. A setup that covers most student needs:
- Perplexity for research and looking things up
- ChatGPT or Claude for explaining concepts and drafting
- Grammarly for proofreading anything you write
- GitHub Copilot (free with Student Pack) if you're an engineering student
- Notion for organizing your notes and coursework
- Canva for presentations and visual projects
Total cost: zero, assuming you get the Student Pack verified.
The Student Pack is worth 30 minutes of effort to set up. GitHub Copilot alone is worth $10/month and you get it free.
