Perplexity AI, known for its AI-powered answer engine, has steadily evolved its personal research assistant offering through a series of strategic feature rollouts.
Deep Research and Labs: From Answers to Projects In February 2025, Perplexity launched Deep Research, a freemium tool designed to deliver in-depth, expert-level answers with real citations. It iteratively searches, reads, and reasons—much like a human researcher—producing detailed reports exportable as PDFs or shareable Perplexity Pages. It notably outperformed many competitors on Humanity’s Last Exam benchmark, though it still trailed OpenAI’s Deep Research in accuracy. (techcrunch.com)
Building on that, Perplexity introduced Labs, a Pro-only feature that handles complex, multi-step projects. Labs can research, write and execute code, and generate structured outputs like reports, spreadsheets, presentations, or even simple web apps. It supports interactive workflows where users can monitor progress and intervene mid-task. (firstaimovers.com)
Memory-Driven Personalization In late 2025, Perplexity unveiled a memory layer for its AI assistants—particularly the Comet Assistant—that remembers user preferences, interests, and past conversation context. This enables more personalized, context-aware responses, positioning the assistant as a “second brain” for everyday tasks and research. (yourstory.com)
Comet Browser Integration Perplexity’s agentic AI capabilities extend into the Comet browser, a Chromium-based AI-powered browser available across platforms. Comet embeds the AI assistant directly into the browsing experience, enabling natural-language control and real-time web search. (de.wikipedia.org)
Recent Enhancements: Structured Outputs and Mobile Reach As of March 27, 2026, Perplexity expanded Deep Research and Pro Search to support generating structured outputs—presentations, spreadsheets, dashboards, websites—directly within the product. Users can now prompt tasks like “Create a presentation analyzing the AI agent market.” The update also introduced secure Plaid integration for personal portfolio access. (perplexity.ai)
Strategic Positioning and Use Cases Perplexity’s personal research assistant suite—spanning Deep Research, Labs, memory, and Comet—targets both personal and professional workflows. An academic analysis of Comet usage found that 57% of agentic queries focused on productivity, workflow, learning, and research, with personal use accounting for 55% of queries. (arxiv.org)
Conclusion Perplexity’s personal research assistant has matured into a multifaceted, agentic AI ecosystem. From delivering deep, citation-backed answers to managing complex projects and remembering user context, the platform now spans web, desktop, and mobile environments. With structured output generation and secure integrations, Perplexity is positioning itself as a powerful AI coworker for both individuals and professionals.
