Comet is Perplexity's agentic browser, and it inherits Perplexity's citation-first DNA while adding live browsing sessions. Where standard Perplexity ranks and cites from its index, Comet also opens and reads pages as part of multi-step tasks, citing what it visits. The result is high citation density combined with real-time fetching. This report covers what Comet cites in 2026, how it differs from index-based Perplexity and from Atlas, its freshness behavior, and what brands should do to get cited.
What Comet Cites Most
Comet keeps Perplexity's broad, citation-dense mix but shifts toward pages it actually opens during tasks. Community content and direct brand sources both rise relative to pure index ranking.
| Source Type | Share of Cited Sources | Notes |
|---|---|---|
| Reddit and community | 16% | Inherits Perplexity's community over-indexing |
| Brand and official sites | 20% | Visited directly during task flows |
| Major news and publishers | 19% | Reached via search then opened |
| Review and aggregator sites | 13% | Comparison and recommendation tasks |
| Documentation and how-to | 12% | Task-completion reading |
| Other web | 20% | Task-specific destinations |
How Comet Differs From Perplexity and Atlas
Comet sits between standard Perplexity and Atlas. It is more citation-dense than Atlas but more fetch-driven than index-only Perplexity.
| Behavior | Comet | Perplexity | ChatGPT Atlas |
|---|---|---|---|
| Citation basis | Index plus visited pages | Ranked index | Pages visited |
| Avg sources per answer | 5.2 | 5.8 | 3.7 |
| Community source share | High (about 16%) | High | Low |
| Fetchability sensitivity | High | Moderate | Very high |
| Session-tied citations | Yes | No | Yes |
Freshness and Recency Behavior
Comet combines Perplexity's strong recency with live in-session reading, so it is both fresh and citation-dense. Pages it cannot fetch during a session lose their citation chance even if they rank well.
- Citation-first heritage. Comet keeps the high source counts Perplexity is known for.
- Session browsing adds fetch dependence. Pages that fail to load mid-task are dropped.
- Community content persists. Reddit and forums remain over-represented at roughly 16 percent.
What Brands Should Do To Get Cited
- Win Perplexity ranking first. Comet inherits its index, so index visibility seeds citations.
- Ensure fetchability. Server-side rendering and fast loads protect against in-session drops.
- Cultivate community presence. Reddit and review content feed the community share.
