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.

Give every AI agent its own isolated browser with a persistent identity
Each profile is generated from a seed so its identity, cookies and logins persist across restarts, and sites see the same returning visitor rather than a new device.
One browser per profile means separate logins, cookies and devices that share nothing, making multi-account automation safe to run in parallel.
Agents get through username and password forms, email confirmation codes, TOTP and SMS two-factor codes, passkeys and permission prompts without stalling.
Press-and-hold, image grid, slider and rotation captchas are solved through human-like input rather than third-party solving keys.

#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.

SpecialistA massive cloud web scraping and automation marketplace, though it lacks Scalebrowser's focus on persistent isolated profiles.
SpecialistAnalyzes scholarly article citations to verify scientific claims, making it superior for academic literature reviews.
