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.
Humanize AI text and check how human it reads
Rewrites AI-generated drafts with natural phrasing, rhythm and flow, and lets you pick light, medium or aggressive rewriting depending on how much change you want.
Scan text before and after humanizing to see which sentences still look machine-written, with colour-coded sentence-by-sentence highlights.
Click any sentence to see alternative rewrite options and fine-tune the output until it matches your own voice.
Returns humanized text in seconds, with word limits per input ranging from 1,000 words on the free plan up to 5,000 words on paid tiers.
