Agent observability, evaluation, and continuous improvement for production AI
Capture spans, traces, and sessions across agents and LLM calls using OpenInference conventions built on OpenTelemetry, so instrumentation stays portable.
Run evaluations at span, trace, and session level to grade retrieval quality, tool use, and final answers across large production datasets.
An in-product agent that inspects traces, diagnoses likely root causes, and proposes fixes that engineers can review before shipping.
Self-host the leading open-source tracing and eval tool when you need to keep trace data inside your own infrastructure.
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.

Excels at experiment tracking and model registry workflows, but is less purpose-built for real-time LLM production observability.
SpecialistProvides reliable medical answers backed by scientific citations, specialized strictly for health and clinical queries.
