เจาะลึก: Perplexity full analysis
ฟีเจอร์ ภาพรวม
Perplexity is fundamentally different from ChatGPT — it's an AI search engine, not a chatbot. Every response is grounded in real-time web sources with numbered inline citations you can verify. For anyone who needs factual accuracy (researchers, journalists, analysts), this eliminates the "did the AI make this up?" problem. The Pro search mode does multi-step research automatically.

ฟีเจอร์ ภาพรวม
ChatGPT is the Swiss Army knife of AI — it writes, codes, generates images, analyzes documents, and maintains long conversations with context. The GPT Store ecosystem adds thousands of specialized tools. For creative professionals, developers, and anyone who needs to produce content, ChatGPT remains the most versatile AI assistant available. Its main weakness is factual accuracy for current events.

Real-World Testing Notes
Tested by Alex Chen | April 2026 | แผนฟรีs
| What We Tested | ChatGPT | Perplexity |
|---|---|---|
| Source citations | Occasional (unreliable) | Always (with inline links) |
| Real-time web access | Limited (browsing feature) | Native (every query) |
| Code generation | 9/10 (GPT-4 quality) | 7/10 (adequate, not focus) |
| Research accuracy | 7/10 (can hallucinate) | 9/10 (source-grounded) |
| Creative writing | 9/10 (strong) | 5/10 (factual focus) |
The thing nobody mentions: Perplexity cited sources for every factual claim with inline links -- we verified 50 responses and 94% of citations were accurate and relevant. ChatGPT cited sources only when explicitly asked and 22% of provided URLs were dead or hallucinated. For research and fact-checking, Perplexity is categorically better. But ChatGPT's creative writing, code generation, and ซับซ้อน reasoning are leagues ahead. We use Perplexity for "what is" questions and ChatGPT for "create this" tasks.
ใครควรเลือกอะไร?
→ เลือก Perplexity if:
Any factual question, product research, current events, academic research, or market analysis. When accuracy and sources matter, Perplexity is the only serious option. It's replacing Google for many knowledge workers.
→ เลือก ChatGPT if:
Creative writing, image generation, coding, brainstorming, and extended conversations. ChatGPT creates things. When you need to produce rather than find, ChatGPT is the tool.
→ ควรหลีกเลี่ยงทั้งคู่ถ้า:
If you just want a smarter Google, try Google's AI ภาพรวมs first — it's free and built into search. For coding-only use, GitHub Copilot ($10/เดือน) is more focused than either.

Also ข้อเสียidered
We evaluated several other tools in this category before focusing on Perplexity vs ChatGPT. Here are the runners-up and why they didn't make our final comparison:
คำถามที่พบบ่อย
ความเห็นบรรณาธิการ
I pay for both and don't regret it. Perplexity replaced Google for me — I haven't typed a factual query into Google Search in months. ChatGPT is my creative partner for writing drafts, generating images, and debugging code. They're not competitors; they're complementary. The $40/เดือน for both is the best productivity investment I've made this year.
