March 20, 2025

AI tools can become highly valuable allies in our daily lives, both in the professional and personal realms, but in order to maximize their benefit, it is essential to understand how to use them. Therefore, we would like to explain how to use Gemini 2.0 Flash, Google’s multimodal and generative conversational AI with enhanced performance and speed capabilities.

Gemini 2.0 Flash is an ideal model to assist with daily tasks such as text drafting, idea generation, assisted learning, image creation, etc. Additionally, its multimodal capability, which allows it to process text, images, audio, video, and code, makes it an exceedingly efficient tool.

It is possible to utilize Gemini 2.0 Flash through its web version or its dedicated mobile application. It is noteworthy that Google has just released its model, allowing any user to access this AI from the browser without needing to log in with a Google account.

How to use Gemini 2.0 Flash from the web and the app

Utilizing Google’s AI is very simple, and its functioning dynamics are quite similar to other models like ChatGPT. First, what you must do is access its platform or download its app (available for Android and iOS) and register.

Once this is done, you will access Gemini’s main panel. In the case of the web version, you will see the space to interact with its chatbot and, on the left, a side menu where you can manage the tool, access previous conversations, and open new chats.

Meanwhile, in the mobile version, the main view will display the interaction panel. To resume old conversations, you will need to click on a message icon that appears in the upper left corner of the screen.

Gemini will give you the option to change the AI model you are interacting with. To do this, there is a drop-down model selector located at the top left in the web version and at the top center in the app. Under this function, the name of the current active version will appear.

In this case, we are interested in selecting the Gemini 2.0 Flash option. However, if you have subscribed to the Gemini Advanced paid plan, other versions such as the experimental reasoning model Gemini 2.0 Flash Thinking, the also experimental Gemini 2.0 Pro, and Deep Research for advanced investigations are available.

With the Gemini 2.0 Flash model active, you can start to take full advantage of this AI. Let us see some usage examples!

How to make an inquiry in Gemini 2.0 Flash

If you need to obtain quick and comprehensive responses without having to dive among articles on the Internet, you can write to (or explain your query with your voice using the microphone to) Gemini, and the AI will take care of condensing and curating content to offer you an answer that addresses your doubts.

How to Create Images

Gemini 2.0 Flash utilizes the capabilities of Image 3, Google’s most powerful image-generating AI, to generate detailed and quality works. Enter the description of the image you wish to create (the more detailed, the better the AI will meet your desires) and within seconds, Gemini 2.0 Flash will bring it to life.

How to plan your vacation

Generative AIs are also a great option for helping you prepare your trips and adventures. In this case, I asked Gemini 2.0 Flash to draft the perfect itinerary in Florence, considering specific conditions and personal preferences: “I would like to travel to Edinburgh with my partener in april. could you do a 3-days itinerary ? Keep in mind that we are both vegetarian and we love Harrry Potter”

How to gather information for your purchases

If you are considering, for example, changing your mobile phone and need to conduct a market study to discover which options best meet your needs, Gemini can be of great assistance.

In response to the query ‘I would like to buy a new phone, one with a good camera, ample memory, and the ability to insert an SD card. What are the best options on the market?‘, the tool offered me a list of mobile phones across different ranges, along with links to their websites or a Google search.

After receiving the initial response, I asked it to conduct a comparison between the mobile phone models it had just recommended. Its response was not entirely satisfactory, as it created a list of advantages and disadvantages for each model, but without pointing out which was the best option.

Finally, it stated the following: ‘I recommend that you consult detailed reviews and comparisons online to get a more comprehensive view of each model and decide which one best suits your needs and budget‘.

Use Gemini 2.0 Flash on the web without logging in

As we mentioned at the beginning of the article, it is no longer necessary to log in with a Google account to use Gemini in the browser. Google has removed this requirement, much like OpenAI did in its time. This is a way to make its AI more accessible to more people, encouraging interest in this tool.

Nevertheless, this option presents several significant limitations that, while allowing users to enjoy part of its potential, are aimed at eventually encouraging users to register with Gemini. You will not be able to upload files to work on them, and it will also be impossible to access chat history, as your conversations will not be logged without an account.

Furthermore, Gemini 2.0 Flash is the default model powering this version, being a capable and powerful AI. However, if you wish to use Gemini 2.0 Thinking or Deep Research, you will need to register.
