How to Use Grok: A Simple and Handy Guide to Get Started

The search "how to use Grok" can mean several things: using Grok on X, talking to Grok, switching it to English, generating an image, testing Grok for free, or understanding its differences from ChatGPT.

X's official Grok help center presents Grok as an AI assistant accessible from X, capable of answering questions and helping with various tasks. On Ai-chatpro, the goal is simpler: choose a Grok model and start chatting without going through X's settings.

How to Get Started With Grok?

To get started with Grok, open X, grok.com, or Ai-chatpro, sign in, then ask a first simple question. On Ai-chatpro, start with Grok 4.3, available for free for quick conversations.

Quick method:

• Open your platform: X, Grok, or Ai-chatpro.
• Sign in if needed.
• Choose the suitable Grok model.
• Write your question in English.
• Add the expected format: summary, list, outline, table, short answer.

How Does Grok Work?

Grok works like an AI chatbot: you write a request, it interprets your intent, then generates an answer. Depending on the platform and offer used, it can also help search, rephrase, analyze, create images, or follow trends.

On X, Grok is interesting for current events and public discussions. On Ai-chatpro, usage is more direct: you select a model and use it as a conversational assistant.

As with any AI, you need to review the answers. Grok can be useful for speeding up research or writing, but it doesn't replace human verification.

How to Activate Grok?

On X, open the app or website, sign in, then look for the Grok icon in the navigation. If you don't see it, check that your app is up to date, that your account is eligible, and that the feature is available in your region.

On Ai-chatpro, activation is simpler: open the chat, choose Grok 4.3 or a Grok PRO model, then start your conversation.

For mobile use, also check your language, account, and subscription settings. Some features may vary depending on the platform.

What Can I Do for Free on Grok?

On Ai-chatpro, you can use Grok 4.3 for free. This model is suited to quick conversations, simple answers, and initial tests.

You can ask it to:

• answer a simple question
• rephrase a sentence
• summarize a short text
• suggest ideas
• prepare a quick reply
• explain a concept
• kick off a train of thought

More advanced models are available with PRO:

The correct phrasing is therefore: Grok 4.3 is free on Ai-chatpro, the Grok 4.20 models are in PRO.

Which Grok Model Should You Choose on Ai-chatpro?

• Choose Grok 4.3 to get started for free. It's enough to ask a question, test the chatbot, rephrase a short text, or generate a few ideas.
• Choose Grok 4.20 Reasoning if you need a more in-depth analysis, a comparison, or more structured reasoning.
• Choose Grok 4.20 Non Reasoning if you want a quick, direct answer, without lengthy analysis.
• Choose Grok 4.20 Multi Agent for complex projects, multi-angle topics, or more strategic analyses.

How to Switch Grok to English?

The simplest way is to write directly in English or start with a clear instruction, such as: "Always answer in English, with a clear, natural, and professional tone."

You can also specify the expected level: beginner, expert, concise, detailed, or educational. If Grok answers in another language, ask: "Redo your answer in English and simplify the technical terms."

This method also works with other assistants like ChatGPT, Gemini, Claude, or Mistral.

What's Better, ChatGPT or Grok?

The best choice depends on the context. Grok is interesting for X, trends, quick answers, and certain creative uses. ChatGPT remains very versatile for writing, analysis, productivity, and workflows already in place.

Grok Image, Video, and Tesla: What Should You Know?

Grok can be paired with image, video, voice features, or certain integrations depending on the platform and offer available. If you're searching "Grok free image" or "Grok free video," always check your account's limits: these features may depend on the plan, country, or platform.

For an image, describe the subject, style, format, lighting, and elements to avoid. Example: "Create a realistic image of a modern office, horizontal format, natural lighting, professional style, no text in the image."

For Grok Tesla, check your vehicle's compatibility, the software version, and access conditions before trying to activate it.

What to Remember

• First define your use case: quick question, research, image, analysis, or comparison.
• Use Grok to speed up a task, but check important information before publishing.
• For a simple answer, Grok 4.3 is enough; to reason further, choose a PRO model.
• To work in English, set the language in the prompt from the very first request.
• Don't send sensitive files, images, or data without checking the privacy settings.
