The ultimate AI platform showdown in 2025: ChatGPT vs Gemini vs Claude, a comprehensive and in-depth review

---

🤖 ChatGPT (by OpenAI)

Since the end of 2022, ChatGPT has begun to appear in various countries. Its growth has made most people feel the power and opportunities of AI. At that time, many voices appeared to embrace AI until it can become your best partner in daily life.

Function:

By 2025, ChatGPT has gone far beyond a simple text-based chatbot. Its core functionality is deeply integrated into everyone's life and work, making it a versatile digital Swiss Army knife. It aims to help more people use AI to run more work, rather than using AI as a replacement tool.

• Advanced Multimodality: ChatGPT can seamlessly process and generate content in different formats. You can upload a meeting video and it will provide a text summary, identify key action items, and even create a presentation. It can listen to voice memos and draft formal emails, and review the code snippets you uploaded to give you better suggestions and optimizations.
• Hyper-Personalization and Memory: The platform now features persistent memory that learns from your previous interactions to provide more relevant and personalized responses. It remembers your preferred writing style, work projects, and personal interests, making it feel less like a tool and more like a true assistant.
• Autonomous Agents and Generic Performance (GPT): The GPT store has grown into a large ecosystem. Users can deploy autonomous agents to perform complex tasks such as planning a vacation (booking flights and hotels based on your preferences), managing a calendar, or conducting market research by browsing the web and writing reports.
• Deep Data Analysis: Its "Advanced Data Analysis" feature can now handle massive data sets. You can upload a complex spreadsheet and tell it in plain language to "identify sales trends for the fourth quarter, visualize the results in a bar chart, and forecast revenue for the next quarter."

How to use it better:

You can give it a specific name and what it does; for example:

You are a professional UI designer. I will give you drawings or descriptions and hope that you can help me optimize or give me better suggestions. For now, I will call you chat designer, and I will call you this way in the future.

🔷 Google Gemini (AiStudio)

Google's latest AI website has the strongest AI reasoning ability. In the latest ranking, Gemini 2.5 has ranked first. I have tried it for more than a month. Because I am mainly a developer, it has very powerful capabilities for developers, and its code capabilities are basically copied and used directly. You only need to describe your problem.

Core advantages and features:

• Top-notch reasoning and logic: Gemini excels at handling complex, multi-step problems, making it a go-to tool for research, analysis, and advanced programming tasks.
• Production-grade code: Its code generation capabilities are a standout feature and are invaluable to developers looking to speed up their workflow and debug complex problems.
• Next-generation innovations: Google continues to innovate with features such as:
  • Smooth voice conversations: Have natural, real-time conversations.
  • Project scaffolding generation: Generate the infrastructure for a project in one sentence.
  • Advanced media content generation: Create high-quality images and other media formats.

Advantages: The most powerful reasoning ability and the top development team, so if you have tried many AI tools but still feel unsatisfactory, then you can give it a try. I believe AiStudio will not let you down.

🤖 Anthropic Claude 3.5

While other platforms focus on pure performance, Anthropic's Claude 3.5 stands out with its firm commitment to safety, reliability, and handling enterprise-level data. For tasks where accuracy, ethics, and deep contextual understanding are prioritized, Claude is the professional's first choice.

• 📚 Unparalleled context window: Claude can process and analyze massive amounts of information in one go — equivalent to hundreds of thousands of words. It can instantly digest an entire codebase, lengthy legal contracts, or deep research papers like chip design manuals, and find the exact details you need.
• 💼 Enterprise-grade intelligence hub: When deployed within organizations, Claude can learn the company's entire knowledge base. It transforms into an intelligent center capable of generating perfectly formatted, compliant documents such as standardized bids, financial summaries, and regulatory reports.
