Create your GEM in Gemini: Custom AI Assistant Step by Step and FREE!

▶

In the world of artificial intelligence, more and more people are looking for personalized assistants that adapt to their daily needs. With Gemini, Google has launched Gems, small AI assistants that you can configure to your measure, without needing to pay a subscription. In my case, the first thing I confirmed was that they are completely free, something that marks a big difference compared to ChatGPT, where you need a premium account to create personalized GPTs.

Differences between Gemini Gems and personalized ChatGPT GPTs

Free Gemini vs Paid ChatGPT

One of the biggest advantages is that you can create and use Gems for free in Gemini. In ChatGPT, however, you need to be a Plus user to access this function.

What limitations and advantages do Gems have

Gemini's Gems focus on simplicity: configure, give instructions, and use. They are faster to implement, although somewhat less advanced in external integration options than OpenAI's GPTs.

How to create personalized assistants in Gemini step by step

Access to the “Discover Gems” menu

From the sidebar you can enter Discover Gems. If you don't see it, check the zoom level: it happened to me and I discovered it was hidden under the three-line menu. and then, a New Gem button appears:

Assign name, functions, and initial configuration

The process is simple: you choose a name for your Gem, you define what operations you want it to perform, and you save it. When I tested it, my first Gems automatically appeared listed, ready to be edited or used.

Edit and manage your Gems

An advantage is that you can return to your Gems, modify instructions, and adapt them. I did it several times until I found a prompt format that really worked.

The power of the prompt: how to write effective instructions

Use of the “Rewrite instructions” button

Gemini includes a button to rewrite the instructions, giving them more clarity and format. However, I found that an error message sometimes appears.

Example instructions to rewrite:

You will act as an SEO expert for Youtube and you will give me optimized title variants as variants for my YouTube channel that include emojis
I will give you the title as input and in a separate paragraph the description of my video currently

I will give you the HTML content in Spanish and you will translate it into English, you will keep the HTML tags and attributes exactly the same. 

Practical tricks to improve prompts

In my experience, insisting with different variants greatly improves the result. When an instruction didn't work, I simply reformulated it and Gemini ended up giving me a more usable prompt.

How to ask Gemini to give you the ideal format

A trick I discovered was asking Gemini in a normal conversation to return the prompt to me in the correct format. Copying and pasting that result into the Gem usually gives better results than writing it from scratch.

Practical examples of useful Gems in day-to-day life

SEO Gem for YouTube (generate optimized titles with emojis)

One of my favorite Gems is an SEO assistant for YouTube. I only enter a title and the description of my video, and the Gem returns several optimized variants with emojis. It's a quick way to have attractive titles ready to capture clicks.

HTML translator Gem (keeping tags and metadata)

Another practical case was creating an HTML translator Gem. My goal was to translate content into English, but without losing the tags or attributes. The Gem worked perfectly: it conserved all the metadata intact.

Other Gem ideas for productivity and automation

• Advanced spelling correction Gem.

Gem for writing short and professional emails.

• Gem for generating to-do lists or meeting summaries.

How to use and pin your Gems in Gemini

Quick access from the sidebar

When you already have several Gems created, you can pin them to the sidebar for immediate access. I did it with my YouTube titles Gem and now I always have it close at hand.

Organization and management of favorite Gems

You can switch between different Gems, edit the ones you already use, and organize your favorites according to the frequency with which you need them.

Combine several Gems for workflows

A useful trick is to chain Gems. For example, first use a Gem to generate a video script and then another to create the optimized titles.

Conclusion
