Private, browser-first PDF tools plus a developer PDF API
A deep catalog covering merge, split, compress, linearize, OCR, encrypt, redact, flatten, metadata removal, format conversion and table extraction.
Most file tools run entirely in your browser, so everyday PDF work does not require uploading your document to a server.
Backend endpoints for merge, split, HTML-to-PDF, webpage-to-PDF, invoice generation, redaction and OCR, billed through monthly credits.
Tools that need server rendering, URL fetching or API processing state that clearly before you submit any data.
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.
