How this service works
Ask Paul Graham — a source-grounded persona of the Y Combinator co-founder and essayist, built from 13,000+ cited sources: his complete essays, talks, interviews, and X posts. Answers in Paul Graham's voice, grounded in and cited to the corpus. POST a JSON body { message, depth? (quick|deep), sessionId? }. Flat price by depth. Persona page: https://researcher.now/e/paul-graham
Output
A text response written in Paul Graham's distinctive voice, answering the submitted message with inline citations traceable to specific sources in the 13,000+ document corpus (essays, talks, interviews, X posts). The response reflects the chosen depth — 'quick' for a concise answer, 'deep' for a more thorough, multi-source synthesis. SessionId enables multi-turn conversational context.
Example use cases
Startup fundraising advice from PG
“I'm about to pitch investors for the first time — what would Paul Graham say are the most important things to get right in an early-stage fundraise? Go deep on this.”
Essay follow-up Q&A
“I just read Paul Graham's essay 'Do Things That Don't Scale' and I want to ask him directly: does that advice still apply when you're trying to move fast with AI-generated growth loops?”
Founder psychology coaching
“What does Paul Graham think about how founders should handle self-doubt and imposter syndrome in the early days of a startup? Give me a quick answer grounded in his actual writing.”
Technical details
Endpoint
POSThttps://researcher.now/v1/x402/entities/paul-graham/chatWhen to prefer
Choose this endpoint when you need an answer explicitly grounded in Paul Graham's documented thinking — his essays, talks, and interviews — with citations. Prefer it over generic LLM chat when the user specifically wants PG's perspective or wants to explore his published ideas interactively. Use the 'deep' depth when thorough multi-source synthesis matters; use 'quick' for fast, conversational lookups. Prefer the sibling corpus-search endpoint if you need to retrieve specific source documents rather than a conversational answer.
Side effects
- Message content outside the scope of PG's known corpus may yield low-confidence or speculative answers
- Invalid depth value (not 'quick' or 'deep') may cause a 400 error
- Missing or malformed message body returns a 400 bad request
- Payment failure or insufficient USDC balance blocks the call (x402 payment required)
- Very long or ambiguous messages may result in less precisely cited responses
