Perplexity AI has quietly become one of the most useful and fastest-growing AI tools of the past few years. While most people still default to Google + ChatGPT for research, Perplexity does something different — and often better: it gives direct, cited, up-to-date answers instead of a list of blue links.
In early 2026, Perplexity is no longer “just another AI search engine.” It’s a full research companion with real-time web access, source transparency, multi-step reasoning, file analysis, and surprisingly strong performance on complex, current-event, and academic queries.
Here’s everything you need to know about Perplexity in 2026 — including features most casual users still haven’t discovered.
What Makes Perplexity Different?
Traditional search (Google) → shows links ChatGPT / Claude → great at reasoning, but knowledge cutoff + no live web Perplexity → combines live web search + reasoning + citations + conversation memory
Core promise: “Ask anything → get a clear, sourced answer → follow up naturally → no hallucinations or outdated info.”
The Main Models & Tiers in 2026
Perplexity runs multiple frontier models behind the scenes and lets you choose:
- Default / Free → Mix of Llama 3.1 70B, Mixtral 8x22B, and Perplexity’s own fine-tunes (fast & good enough for most questions)
- Pro Search (default on paid) → GPT-4o + Claude 3.5 Sonnet + Gemini 2.0 Pro routing (auto-picks best model per query)
- Sonar Online → Perplexity’s custom web-tuned model (very fast, excellent at current events)
- Claude 3.5 Sonnet / Opus → Available on Pro & Enterprise (best reasoning)
- GPT-4o / o1-mini → Available on Pro & Enterprise (strongest on math & code)
Hidden behavior: Free users are frequently A/B tested on different base models — that’s why some days Perplexity feels dramatically smarter or more concise than others.
Standout Features Most People Underuse
- Focus Modes (Still Underrated)
- Web Search → classic Perplexity (live sources)
- Academic → prioritizes peer-reviewed papers, arXiv, PubMed
- Writing → longer, more structured answers (great for essays, reports)
- YouTube → searches & summarizes video content with timestamps
- Wolfram Alpha → forces precise math, calculations, data lookups
- File Upload + Analysis (Pro feature)
- Upload PDF, DOCX, CSV, images → ask questions about them

- Collections & Threads
- Save entire research threads as “Collections”
- Share collections with teammates (Pro/Enterprise)
- Collections keep full context — perfect for long projects
- Copilot Mode (Real-Time Agentic Research)
- Turns Perplexity into a step-by-step researcher

- This mode is now stronger than most people realize (especially on Pro)
- Perplexity Pages
- One-click “create shareable research page” from any thread

Final Verdict
Perplexity is not trying to replace ChatGPT or Claude. It’s trying to replace Google + ChatGPT combined — and in many research-heavy use cases, it already does.
If your workflow involves:
- Needing current information
- Wanting automatic citations & sources
- Uploading files/PDFs for analysis
- Building shareable research reports
…then Perplexity Pro is still one of the strongest tools available in 2026 — often faster and more accurate than the competition for factual queries.
Quick test you can do right now: Go to perplexity.ai → ask: “What are the top 5 new smartphones released in January–February 2026, with current prices and key differences?”
You’ll see why people quietly prefer it for anything that needs to be true and up-to-date.
