Key Features and Specifications

1. Real-Time Web Search with Citations

Unlike ChatGPT or Claude, which rely on a knowledge cutoff or require plugins for web access, Perplexity Comet is natively connected to the live web. It fetches current data and always cites its sources—something highly appreciated in academia and journalism.

Example Use Case:
You’re a content marketer writing about the latest Google Search algorithm update. Ask Comet, “What are the changes in the July 2025 Google core update?” and it will provide not only an answer but also cite reputable sources like Search Engine Journal, Moz, and Google’s official blog—all in real-time.

2. Follow-Up and Threaded Conversations

Perplexity Comet supports contextual follow-ups, letting you ask more questions within the same thread. It remembers the context of your conversation, enabling deeper exploration of complex topics.

Scenario:
Start by asking, “What is generative AI in 2025?” Then follow up with “Who are the top companies leading this space?” and then “What are the latest patents filed by OpenAI?” Comet threads this conversation intelligently.

3. Academic Search via ArXiv and Semantic Scholar

Perplexity Comet connects to platforms like ArXiv, Semantic Scholar, and Google Scholar, making it ideal for academic researchers.

Benefits:

• Instant access to peer-reviewed papers.
• Summarized abstracts.
• Citation links in APA/MLA format.
• PDF access to research papers.

4. Multimodal Capabilities (Images, Code, Tables)

Comet supports image uploads, coding support (Python, SQL, etc.), and tabular data analysis.

Technical Breakdown:

• Image support: Upload a diagram or screenshot for the AI to analyze.
• Code snippets: Ask Comet to debug Python code or generate a SQL query for a specific business logic.
• Tables: Ask it to convert data into tables, charts, or CSV format.

Example:
Upload an image of a complex marketing funnel and ask, “Explain this diagram and how it relates to inbound lead generation.”

• Web App: Supports all browsers.

How it Works:

• Type in a query.
• Copilot follows up with refined sub-questions automatically.
• Results are nested and structured with citations.

7. Voice Input and Conversational UI

You can talk to Comet just like Siri or Google Assistant. This is ideal for on-the-go research or when multitasking.

Use Case:
While walking or driving, ask, “Summarize the latest AI developments in Europe this month,” and receive a readable summary with links to sources.

8. Source Filtering and Trust Ranking

Comet ranks results based on source trust scores, so information from sources like MIT, Harvard, Bloomberg, etc., are ranked higher than random blogs or user forums.

Example:
You can even specify: “Only include government sources,” or “Prefer academic journals.”

9. PDF & YouTube Summarization

Upload a PDF or paste a YouTube URL, and Comet will extract and summarize the content.

Real Example:
Upload a 100-page whitepaper and get a summary in < 30 seconds. Paste a YouTube lecture URL and get:
