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.
Antispam service that keeps junk mail, phishing and viruses out of every inbox
Works with iPhone, Android, Mac, PC, Office 365 and general IMAP/POP accounts, so one filter protects every device that reads the same mailbox.
Every new message is analysed before delivery, and suspicious senders, malicious links and infected attachments are stopped instead of reaching you.
Each time you mark something as spam or confirm it is legitimate, the filter learns your preferences and gets more accurate over time.
Held messages are not lost. You can open your Spamdrain account, inspect what was blocked, and release false positives with a click.
