Now there are so many AI options and it's confusing, right? But actually, the current four AI "giants"โChatGPT, Claude, Gemini, and Perplexityโeach have very different specializations and "vibes."
1. ChatGPT (OpenAI)

ChatGPT is like that student council member active in all activities. It was the first AI to go viral, and it's still the safest choice when you're confused about which AI to use.
- Fully Customizable (GPT Store): You can find or create a specialized AI for specific tasks. For example: an AI for creating TikTok content, an AI to accompany you in learning English, or even an AI to help create recipes from leftover ingredients in the fridge.
- Top Voice & Image Features: Its voice chat feature (Advanced Voice Mode) sounds very natural, not like a stiff robot. Plus, it has DALL-E 3, which is great at creating aesthetic images just by typing text commands.
- Great at Coding & Data Processing: If you have a huge Excel file or buggy code, just throw it at ChatGPT. It will fix it and even create a graph immediately if asked.
๐ก When to use it? When you need one AI for everything (creating images, chatting, helping with daily tasks, or brainstorming creative ideas).
2. Claude (Anthropic)

If you feel that other AIs' writing is stiff and "looks obviously made by a robot," well, you haven't met Claude. It's known to be the smartest with the most human-like language style.
- Smooth and Natural Language: Claude's articles, essays, or emails are very pleasant to read. They flow, have empathy, and don't overuse typical AI clichรฉs.
- Great at Reading Long Documents: Do you have a PDF file as thick as a savings book or a financial report hundreds of pages long? Give it to Claude. It can read everything at once without getting confused, and you can ask questions about the document's content.
- Artifacts Feature (See Results Instantly): If you ask Claude to create website code or a simple design, it will open a separate window next to the chat room to show the result directly. You can see how it turned out immediately.
๐ก When to use it? When you need help with creative writing (so it doesn't seem like you used AI), or when you need to summarize very thick documents/books.
3. Gemini (Google)

Gemini is Google's champion. Its main advantage is clear: it directly connects with all the Google apps you use every day.
- Integrated with Gmail & Google Docs: You can ask Gemini, "Find the email from my boss last week about project A, then summarize it in Google Docs." It can do that in seconds.
- Very Strong Memory: The latest version of Gemini has a very large memory capacity (context window). You can input a one-hour YouTube video or a long meeting recording, and it understands from the first second to the end.
- Up-to-Date: Since its parent is Google (king of search engines), Gemini is fastest when asked about news or information that just happened today.
๐ก When to use it? When you're working with Google Workspace (Gmail, Drive, Docs) or when you need to find the latest news/info in real time.
4. Perplexity AI

Perplexity is a bit different from the three AIs above. It's not the type of AI for casual conversation, but rather a modern search engine. Think of it as Google Search, but a super smart version without ads and without the hassle of clicking one website at a time.
- Never Hallucinates (Has Sources): Every time you ask a question, Perplexity searches the internet, summarizes the answer, and provides numbers/links to the sources. So you can check which website the information came from. No more AI "hallucinations" or made-up facts.
- Pro Mode (Deep Research): If you activate this mode, Perplexity will ask you clarifying questions to ensure what you're looking for, then it will dig through the internet thoroughly to provide a complete report.
- Can Create Article Pages: Your research results can be turned into a neat article web page ready to share with others with just one click.
๐ก When to use it? When you're working on a thesis, school assignment, market research, or looking for valid information that requires evidence and clear sources.
๐ In Short:

| Want an all-in-one AI that can also create images | ChatGPT |
| Want to write great articles + analyze thick documents | Claude |
