AI that checks whether Reddit claims are actually backed by their sources
A Validate Claim button appears on Old Reddit comments that contain links, so verification is one click away instead of a separate research session.
Instruction fine-tuned models break a comment down into the discrete factual claims the author is implicitly or explicitly asserting.
The tool fetches the linked source and evaluates each claim against it, showing where the citation does and does not hold up.
The codebase is public and the roadmap is shared, covering multi-source comments, Reddit posts, Twitter, and Wikipedia support.
Real-time AI answer engine and research workspace combining live web citations with frontier reasoning models.
Executes multi-step iterative web and document research across hundreds of sources, cross-checking facts and generating structured, citation-backed analytical reports that can be exported as PDFs or shared as interactive Perplexity Pages.
Lets Pro and Max subscribers switch dynamically between Perplexity's in-house Sonar models and top external models (including Claude 4, o3-pro, and Gemini) or compare multi-model reasoning outputs side by side.
Provides dedicated project workspaces where users upload local PDFs, spreadsheets, and text files, configure custom assistant instructions, and run queries that combine private document retrieval with live internet search.
Extends Perplexity from passive Q&A into agentic execution, turning high-level user requests into completed workflows, multi-tab browser actions, and automated data synthesis via the Comet ecosystem.

SpecialistOffers a comprehensive free index of academic literature, but lacks conversational chat synthesis for general web queries.


SpecialistFocuses exclusively on peer-reviewed scientific papers for evidence-based answers, unlike Perplexity's broad general web search.


Combines privacy-focused web search with AI summarization, though it requires a paid subscription for full access.
SpecialistAnalyzes scholarly article citations to verify scientific claims, making it superior for academic literature reviews.
Generates structured, cited answers from live web queries, though with less polished UI and advanced model options.
AI detector that highlights evidence, not just a score
