What Are Gemini Gems?

Gemini Gems are like custom-made AI assistants that you create within Google Gemini. They're designed to be highly specialized for a particular task, saving you time and giving you more consistent results than if you were to write a long, detailed prompt from scratch every time.

Think of it this way: instead of repeatedly telling a general-purpose AI, "I need you to act as a marketing expert, with a professional yet friendly tone, and give me three social media post ideas for a new product launch," you just create a "Social Media Guru" Gem once. Then, every time you need social media help, you simply open that Gem and give it the quick instruction, like "Give me posts for the new product launch." The Gem already knows its persona, its tone, and its purpose.

What is Study Mode

The new ChatGPT Study Mode is designed to make learning feel more like having a personal tutor by your side. Instead of just giving you the answer, it walks you through topics step by step using Socratic questioning - asking questions, giving quizzes, and offering feedback along the way. This keeps you actively involved, helps you really understand the material, and builds critical thinking skills. Whether you’re doing homework, studying for an exam, or trying to wrap your head around a tricky concept, Study Mode adjusts to your pace and keeps things engaging - like having your smartest, most patient tutor who’s available anytime you need.

The Study Mode is available to all logged-in users - including Free, Plus, Pro, and Team plans.

I demoed Google NotebookLM to my friend. He said what's the big deal? ChatGPT can also do all these!

On the surface, they both look like "talk to a bot" interfaces. The key difference lies in their fundamental purpose and design.

If your friend also tells you the same thing, here’s a simple way to frame it for your friend:

ChatGPT is like talking to a brilliant person who has read most of the internet. It's a generalist and a creative partner.
NotebookLM is like hiring a genius research assistant who has only read the specific documents you gave them. It's a specialist and a personal analyst.

This distinction is the source of all its advantages.

This is one of the most significant technical advantages NotebookLM has, as its entire purpose is to work with large amounts of your specific content.

The "number of tokens supported" is technically called the context window. Think of it as the AI's short-term memory for a single conversation or query. A larger context window means it can "read" and "remember" much more information at once to answer your questions.

Here is a comparison table that translates these technical limits into practical terms.
