Dead Man Walking· 0/100
An LLM can do most of what this tool's UI promises. No moat, no agent presence.
“Perplexity is a UI wrapper around search + LLM synthesis. Claude, GPT-4, and open models can all do web search now via plugins or native integration. The citation format and source linking are table stakes, not defensible. Perplexity has no proprietary data, no regulatory moat, no network effects, and no trust advantage — it's a commodity research interface competing on speed and UX alone.”

- Physical-world coupling

- High-trust catastrophic workflows
- Multi-party coordination
- Brand / community / taste
An LLM alone could replace
- Search the web and synthesize results into a coherent answer
- Cite sources and provide links to supporting documents
- Follow up with clarifying questions to refine research
- Generate research summaries across multiple topics

How to defend
Perplexity needs to own a vertical where research mistakes are costly (legal due diligence, medical research, financial analysis) and build liability insurance or expert review into the product. Alternatively, build a two-sided network of researchers and clients where the platform coordinates expertise — stop being a search UI and become a marketplace for research labor.
- Ship an MCP server and list it on Stork — biggest single point gain (+25).
- Get listed in the Anthropic MCP registry, Cursor, or Claude Desktop (+20).
- Add a usage-based or per-call tier; per-seat-only pricing dies when agents replace seats (+15).
- Expose API-key auth with a self-serve sandbox tier; remove sales-call gates (+15).
- Publish an OpenAPI spec at /openapi.json or /.well-known/openapi (+10).
