Top 10 Free AI Tools for Students in 2025

As a student of undergrad or postgrad, you need to balance classes, assignments, exams, part-time jobs, and your personal life all at once. A lot of students share with me that they often feel like they’re racing against the clock.

That’s why I often remind students that the smartest learners aren’t always the ones who study the most hours. They’re the ones who use the right tools to study better and faster.

Over the past few years, one set of tools has changed the way we learn: artificial intelligence. AI has moved from being a big idea in tech labs to something every student can use from their phone or laptop.

I’ve worked with thousands of students at Shakil Education Group, and I’ve tested dozens of AI tools myself. Some tools are gimmicks. Some are too complex. But a few truly make learning easier, faster, and more enjoyable.

In this guide, I’ll share the 10 AI tools I believe every student should use in 2025. These aren’t random picks. I have seen students use successfully for writing essays, organizing notes, solving math, preparing presentations, and even learning to code.

Let’s dive in.

1. Notebook LLM – Your Smart Study Notebook

Notebook LLM is a supercharged version of your study notes. You can upload documents, lecture notes, or research papers, and it becomes your personal study assistant. 

Instead of stressing out through dozens of pages before an exam, you just ask it questions. “What’s the main theory from chapter 4?” or “Summarize this lecture in simple words.” Notebook LLM answers instantly.

Why it’s helpful for students

  • Keeps all notes in one place.
  • Makes revision simple.
  • Answers in your own context.

Advantages

  • Great for exam prep.
  • Saves hours of searching.
  • Works like a personal tutor.

2. Google Gemini – AI Inside Google Tools

Google Gemini is one of my personal favorites because it’s built into apps students already use. If you’re writing an essay in Google Docs, Gemini can suggest better phrasing, fix grammar, or even draft paragraphs.

In Google Slides, you can type a short prompt like “Make a presentation on climate change,” and Gemini will create slides instantly. It even works in Gmail for writing clear emails to professors or scholarship offices.

Why it’s helpful for students

  • Works inside familiar Google apps.
  • Stronger than simple chatbots because it links to Google Search.

Advantages

  • Reliable and accurate.
  • Saves time across multiple tasks.
  • Seamless with Google Drive.

3. Grammarly – Write with Confidence

Grammarly is a tool I recommend to every student, no matter their subject. Writing is part of almost everything: essays, emails, reports, and even job applications.

Grammarly checks and fixes your grammar, spelling, and punctuation. It also suggests better word choices and checks tone. For serious work, the plagiarism checker is very useful.

  • Works across apps and browsers.
  • Plagiarism checker available.
  • Free version is strong enough for daily use.

4. QuillBot – Rewriting Made Simple

QuillBot is also very popular for students because it makes writing so much easier. If you’ve ever stared at a paragraph wondering how to put it in your own words, QuillBot can step in and do the heavy lifting.

It also checks your grammar, summarizes long texts, and even helps with citations. You can use it when you are working on research papers either to make complicated material easier to understand. It’s like having a smart writing buddy who helps polish your work and keeps things stress-free. 

Why it’s helpful for students

I mean you cannot go through 1200 page pdf when exam is knocking at the door. ChatPDF makes them easy. Upload a PDF, and you can ask questions like, “What’s the main argument?” or “Summarize section 2.”

It saves hours of reading and makes studying more efficient. I’ve seen students use it for everything from history articles to medical research papers.

6. ChatGPT – The All-Round Study Buddy

ChatGPT is one of the most popular AI tools today. Think of it as a helpful friend who can explain hard topics in simple words, help you write essays, solve math problems, or guide you like a tutor.

But here’s the important part, I always tell students not to use it as a shortcut. Instead, treat it like a study buddy. It’s there to give you ideas, make learning easier, and keep you on track—not replace your own effort.

Why it’s helpful for students

  • Works across multiple subjects.
  • Gives clear explanations.

Advantages

  • Versatile.
  • Free version is powerful.

Notion has always been a go-to planner. Once you add AI into the mix, it feels like a whole new level of productivity. Right now, if you are switching through multiple apps, you can keep your to-do lists, assignments, and class notes all in one clean, organized space. No more sticky notes or messy folders.

The AI makes it even better—it can shrink long readings into bite-sized summaries, give you a starting point when you’re staring at a blank page, and gently remind you about upcoming deadlines. Honestly, it feels less like an app and more like that super-organized friend who always knows what’s due, when it’s due, and how to help you get it done.

Why it’s helpful for students

  • Keeps life organized.
  • Useful for group projects.

If you’ve ever spent hours staring at your screen because of one tiny coding error, you know the pain. AskCodi is like a helpful friend who actually understands your code. You paste in what you’re working on, and it explains what’s wrong, suggests fixes, or even writes small chunks of code for you.

It works with lots of programming languages and feels a bit like having a patient tutor who never gets tired of your questions.

It’s great for brushing up before an exam or learning on your own at home. I’ve seen many students use it as a stand-in for private tutoring when hiring a teacher wasn’t possible.
