Liveness and deepfake detection for identity verification
Active and passive liveness combined with deepfake detection across RGB texture, motion, depth and neural-anomaly signals for higher assurance.
Identifies AI-generated or manipulated images and video, including real-time deepfake detection in online meetings.
1:1 face matching, photo-to-ID document comparison and 1:N face search for de-duplication and identity resolution.
Integrate via SDK or API, or deploy on-premises and in air-gapped environments to meet data-residency rules.
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.

#1
Leverages Google's vast search index for real-time answers, but offers a standard chat interface rather than deep research feeds.
#2Provides exceptional analytical depth and writing quality, but does not focus purely on web-sourced search summaries.

Integrates real-time social data search for breaking news, but leans more toward casual chat than structured research.

Delivers agentic multi-source research and page generation, but can feel more cluttered than Perplexity's clean answer engine.

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.
