An invisible AI copilot that solves coding interview problems in seconds
The model inspects the problem and returns several viable algorithms sorted from worst to best time complexity, including for problems that are not published anywhere.
Pick an algorithm and receive idiomatic code for your chosen language, edge-case tests and a written complexity analysis within seconds.
Undetectable global hotkeys run at a privileged level, and the window is designed to stay invisible in screenshots and screen-sharing software.
Mirror every output to a phone, tablet or second laptop so you never need to open anything on the machine being proctored.
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.
