Perplexity evolved from search-with-citations into a full research platform. Deep Research runs multi-step investigations that take 2–5 minutes and produce comprehensive reports with sources — replacing hours of manual research. Perplexity Pages creates shareable, structured research documents anyone can read. Pro Search includes access to Claude, GPT-4o, and Sonar models for different task types. Shopping mode surfaces product comparisons with price tracking. The answer engine that replaced Google Search for research-heavy workflows.

SNEWPapers is an AI-powered research platform built on 6+ million stories extracted from 3,000+ American newspaper titles spanning 250 years — from the 1730s through the 1960s. Unlike keyword-search archives, it uses semantic AI to let users search by concept and meaning, filtering across 24 main categories, 1,000+ subcategories, and geographic or date ranges. The standout feature is The Sleuth: an AI research assistant that independently searches the archive and returns answers with direct citations from period newspapers. Paired with Today in History timelines pulled straight from source documents, it gives historians, journalists, and curious readers a lens into events as they were actually reported — not as they're summarized in modern encyclopedias. The platform distinguishes itself sharply from general-purpose LLMs: this content was never in ChatGPT's training data. SNEWPapers is a genuine primary-source research layer that AI tools can't replicate from their weights alone, making it particularly valuable for investigative journalism, academic history, and anyone tired of AI hallucinating citations from 1850.
Reviewer scorecard
“Deep Research is legitimately impressive for technical evaluation — comparing libraries, auditing security postures, understanding architecture decisions. What used to take 2 hours of reading docs and Stack Overflow now takes 5 minutes and comes with citations I can verify.”
“The engineering here is genuinely hard — OCR-ing and semantically indexing 6M scanned newspaper articles at this scale is non-trivial, and the 1,000+ subcategory taxonomy suggests serious curation effort. If they ever open an API, this becomes a compelling RAG data source for historical context.”
“Citations remain the core differentiator vs ChatGPT. Every claim is sourced and you can click through. Hallucination risk drops dramatically when the model knows it has to cite. Deep Research is good but sometimes slow — it works best when you have a few minutes, not seconds.”
“OCR quality on 18th and 19th-century newspapers is notoriously bad, and semantic search on noisy OCR text is a recipe for confident-sounding but wrong results. The pricing is opaque — which usually signals expensive. Wait for independent accuracy benchmarks before doing serious research here.”
“Perplexity Pages is the underrated bet — turning AI research into shareable documents is how knowledge workers will collaborate in the future. The roadmap (Deep Research, Pages, shopping, Pro with multiple models) is building the AI-native knowledge platform, not just a better search engine.”
“Primary-source AI research tools are a distinct and underserved category. Historical context that isn't in any LLM's training data is genuinely scarce and valuable. Expect university libraries and investigative journalists to become core users as the platform matures.”
“For anyone writing historical content — essays, podcasts, documentaries — this is a goldmine. Seeing how the Lincoln assassination was actually reported in 1865, not how Wikipedia summarizes it, changes everything about the story you tell. This is primary source access at consumer scale.”
