4. Accuracy, Citations & Factual Reliability
Perplexity AI
- Shines in live or technical queries: sources are cited after each fact or answer, and multiple web sources are cross-verified.
- Accuracy is exceptionally high for time-sensitive or research-heavy queries.
- Great for students, journalists, and anyone needing credible, citable info.
ChatGPT
- Strong at creative, nuanced, and conversational output but may “hallucinate” facts, especially when not browsing the web.
- Browsing mode helps, but returns fewer references and may require manual verification for high-stakes research.

5. Real-Time Data & Web Search Capabilities
- Perplexity: Real-time web crawling is always active, ensuring data reflects the latest news, stats, and trends. You can instruct it to only use academic sources or limit results for deeper research.
- ChatGPT: Can browse the web (on Pro/Plus plans), but web search is not always on by default—designed more for “knowledge-based” or dialogic assistance than as a pure answer engine.

Perplexity offers a unique edge by letting users switch between AI engines: GPT-4o, Claude, Gemini, Grok, or its proprietary R1, optimizing for speed, accuracy, or reasoning. Specialized “Spaces” or Labs let users build projects or explore with niche focus.
ChatGPT runs on OpenAI’s proprietary models (latest: GPT-4o), plus custom “GPTs” for specific workflows, coding, and browser integrations.
8. Multimodal Input: Text, Image, Audio & File Handling
Both tools now boast multimodal capabilities:
- Text & Code: Both excel, though ChatGPT has the edge in extended code debugging and creative writing.
- Images: Both can interpret, describe, or generate, but ChatGPT (Pro) supports more advanced visual reasoning.
- Audio & Voice: Available in both, with slight edge to ChatGPT for “real conversation” synthetics.
- Files/Documents: Both can process attached files, but Perplexity Labs is tuned for research projects and batch uploads.
9. Pricing & Value for Money
- Perplexity: Free with limits; Pro: $20/month; Max/Enterprise: $200/month (extra features: advanced “Comet” browser, priority searches, research labs, etc.)
- ChatGPT: Free for GPT-4o; Plus (with GPT-4 Pro, browsing, vision, and file analysis): $20/month. Enterprise plans scale for large teams.
