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.
An AI research workspace where every answer points to the exact passage it came from
Search more than 300 million papers across medicine, physics, and other fields, filter by journal, year, or citation count, and save relevant results to your library with one click.
Upload papers, notes, slides, and recordings; Anara indexes them all and lets you ask questions scoped to a single file, a folder, or your entire collection.
Every answer points to the exact passage it came from, verifiable in one click — the core differentiator versus general chat assistants.
Turn a folder of papers into a structured table with one row per paper and one column per question, with every cell cited, then export to CSV or Excel.
Offers deeper conversational reasoning and coding agents, but lacks Perplexity's dedicated inline citation-first search layout.
