The AI Tools the World Is Searching For: Gemini, ChatGPT, Grok, DeepSeek and Perplexity.

Artificial intelligence used to be a topic for science magazines and research labs. Now it is something people open on their phones before breakfast. In Google’s Year in Search 2025 report, Gemini, Google’s AI assistant, claimed the top spot as the most trending search term globally. That ranking measures growth in interest, not raw volume. Google explains that it reflects the topics with the largest increase in interest compared with the previous year, which is why everyday queries like the weather never make the list. routenoterazomua

Gemini was not alone. DeepSeek also made the global top ten, and other tools such as ChatGPT, Perplexity, Grok and Google AI Studio drew steady attention. A technology that was a niche research topic a few years ago now competes with sport, politics and entertainment for public curiosity. greaterbelize

That raises a practical question: with so many tools, which one should you actually use? This guide explains what each one is, where it shines, and how to choose. It also looks at what this wave of AI means for science and technology.

Why AI tools suddenly dominate search

Three forces came together.

Accessibility. Most of these tools run in a browser or a phone app, and many offer free tiers. You don’t need to write code or own expensive hardware.

Usefulness. Early chatbots were entertaining but unreliable. Current tools can summarize long documents, explain difficult ideas, debug code, generate images and answer questions with sources. Students, freelancers, researchers and small business owners all find real uses for them.

Cultural momentum. Viral trends push millions of people toward these tools. In the United States, searches like “AI action figure,” “AI Barbie,” “AI Ghostface” and “AI Polaroid” led the list of top trends. When something is both useful and fun to share, search interest grows quickly. searchenginejournal

Gemini: Google’s all-round assistant

Gemini is Google’s AI assistant, built to handle text, images, audio and video. It can answer questions, draft emails, summarize documents, help with planning and explain complex topics in plain language.

Its biggest strength is integration. If you already use Google Search, Gmail, Docs, Drive or an Android phone, Gemini fits into your routine without extra effort. Interest in it also tracked Google’s product moves. Searches spiked from September, when Google rolled out AI updates across Chrome, Search and Android, and a new model generation followed in November. euronews

Best for: everyday questions, document summaries, planning, and anyone who lives in the Google ecosystem.

Nano Banana Pro: image creation and editing

Nano Banana is the popular nickname for Google’s image generation and editing model available through Gemini, and Nano Banana Pro is its more advanced version. It went viral because it is so simple. You upload a photo, describe the change in plain language, and the AI makes the edit. That could mean swapping a background, changing the style or turning a portrait into an illustration.

This lowers the barrier to creative work. Tasks that once required design software and hours of practice can take minutes. Small businesses can mock up product visuals, teachers can illustrate lessons, and creators can experiment freely.

There is a responsible-use side. AI-edited images can be hard to tell apart from real photographs, so label AI-generated content and don’t use anyone’s likeness without permission.

Best for: creative edits, social media graphics, presentations and quick design ideas.

ChatGPT: the tool that started the boom

ChatGPT, made by OpenAI, introduced conversational AI to the mainstream, and for many people “using AI” still means “using ChatGPT.” It is a flexible general-purpose assistant for writing and editing, brainstorming, learning new subjects, coding help, data analysis and language practice. It also supports a wide range of add-ons and integrations, so it adapts to many workflows.

Its main strength is versatility. If you aren’t sure where to begin, ChatGPT handles an unusually broad range of tasks competently.

Best for: writing, studying, coding assistance, brainstorming and general-purpose use.

Grok: the assistant connected to X

Grok comes from xAI and is closely tied to the social platform X, formerly Twitter. Its distinguishing feature is access to public conversations on X, which gives it a real-time flavor that many other assistants lack.

That makes Grok interesting for following breaking topics or gauging public reaction to an event. The trade-off is that social media is noisy and sometimes wrong, so verify anything important against reliable sources.

Best for: following live discussions and trends on X.

DeepSeek: the low-cost challenger

DeepSeek is a Chinese AI company that made headlines by releasing models that rivaled the performance of state-of-the-art systems. Some of its models are released as open-weight, meaning developers can download them, study them and adapt them for their own projects. routenote

This matters for science and technology because openness speeds up experimentation. Students, researchers and startups with limited budgets can build on these models instead of paying for access to closed systems.

One caution applies to every AI service, DeepSeek included. Providers handle user data differently, and rules vary by country. Before entering sensitive personal, financial or business information into any tool, read its privacy policy and decide whether you’re comfortable with it.

Best for: developers, researchers and anyone interested in open, affordable models.

Perplexity: the answer engine

Perplexity is built more like a search engine than a chatbot. When you ask a question, it searches the web and gives you a written answer with links to its sources, so you can check where each claim came from.

For research, that is a major advantage. One of the biggest weaknesses of AI assistants is that they can sound confident while being wrong. A tool that shows its sources lets you verify information instead of simply trusting it. Students, journalists and professionals all use it as a starting point, though it is still wise to open the cited pages and confirm the details.

Best for: research, fact-finding and answers you can verify.

Google AI Studio: where people build with Gemini

Google AI Studio is a browser-based workspace for experimenting with Google’s Gemini models. Unlike the consumer chat apps above, it is aimed at people who want to test prompts, compare settings and prototype their own AI-powered applications.

You don’t need to be a professional engineer to try it. A student can see how a model responds to different instructions, and a developer can go from idea to working prototype quickly. For anyone curious about how these systems work under the surface, it is an approachable place to learn.

Best for: students, developers and tinkerers who want to build their own AI projects.

Quick comparison

How to choose the right tool

Start with your goal, not the brand name.

• Just getting started: try Gemini or ChatGPT. Both are friendly, flexible and free to begin with.
• Creating images: use Nano Banana Pro.
• Researching with sources: use Perplexity and check the links it provides.
• Following live conversation: try Grok.
• Building something: explore Google AI Studio or DeepSeek’s open models.

Many people end up using two or three together. You might research a topic in Perplexity, draft your thoughts in ChatGPT or Gemini, and create visuals with Nano Banana Pro. The best test is to give each tool the same task and compare the results.

Using AI tools responsibly

Powerful tools come with habits worth building.

Verify important facts. Every AI assistant can make mistakes, including confident ones. Double-check numbers, dates, medical information and legal claims.

Protect your privacy. Avoid pasting passwords, financial details or confidential documents into tools you haven’t reviewed.

Be transparent. If you publish AI-generated text or images, say so. Readers value honesty, and it protects your credibility.

Keep thinking for yourself. AI is best used as a helper that speeds up your work, not a replacement for your own judgment.

What this means for the future of science

These tools are already changing how knowledge work gets done. Researchers use them to scan large volumes of papers, students use them to understand difficult topics, and small teams build products that once needed much larger budgets. Open models like DeepSeek’s show how competition can make the technology cheaper and more widely available, while products like Gemini show how AI is being woven into software people already use every day.

Expect tools to become more capable, more specialized and more deeply embedded in phones, browsers and workplace software. The skill that will matter most is knowing how to ask good questions, check the answers and combine tools sensibly.

Final thoughts

The rise of Gemini to the top of Google’s global trending searches, alongside DeepSeek and a crowd of other AI tools, shows that artificial intelligence has moved from the margins into everyday life. There is no single best tool. The right choice depends on whether you want to write, research, create or build.

Pick one or two to start, use them on real tasks, and revisit your choices every few months. The field changes quickly, and the tool that suits you best next year may not exist yet.

Features, pricing and availability change frequently, so check each tool’s official site before relying on specific details.
