Perplexity Extension

Extracts and summarizes the full text content of any webpage using Perplexity's backend LLM, preserving key context and structure. The extension captures the DOM content from the active tab, sends it to Perplexity's servers for processing, and returns a concise summary that maintains semantic meaning. Works across article formats, blog posts, documentation, and news pages without requiring manual text selection.

Accepts natural language questions about the current webpage's content and returns answers grounded in that page using retrieval-augmented generation. The extension extracts relevant passages from the page DOM, sends both the question and page context to Perplexity's LLM backend, and returns answers with implicit citations to page sections. Supports follow-up questions that maintain conversation context across multiple turns.

Enables users to ask questions scoped to the current domain or website without needing to select specific text or navigate away from browsing. The extension infers domain context from the active tab URL and can route queries to search Perplexity's index for information specifically from that domain, or answer questions about the domain's general topic. Supports rapid-fire queries without page reload or context loss.

Generates shareable links for answers and summaries produced by the extension, allowing users to share specific insights with collaborators without requiring them to visit the original webpage or have the extension installed. The link encodes the question, answer, and source page context, creating a persistent reference that can be embedded in documents, shared in chat, or bookmarked. Backend stores link metadata for retrieval.

Allows users to select specific text passages on a webpage and submit them to Perplexity for analysis, explanation, or follow-up questions. The extension captures the selected text via the DOM selection API, preserves surrounding context for coherence, and sends it to the backend for processing. Supports context menu integration for one-click submission without opening the extension sidebar.

Maintains a persistent conversation thread within the extension sidebar that allows users to ask follow-up questions about the current page without losing context. Each turn in the conversation references the page content implicitly, allowing natural language follow-ups like 'explain that more' or 'give me an example' without re-specifying the page context. Conversation state is stored in the extension's local storage or session storage.

Provides toolbar button and keyboard shortcut access to Perplexity's capabilities from any browser tab without requiring navigation or context switching. The extension registers a Chrome extension icon in the toolbar that opens a sidebar or overlay interface, and may support keyboard shortcuts (specific keybindings undocumented) for rapid access. Integrates with Chrome's extension API for toolbar presence and tab context access.

Automatically extracts and parses the main content from webpages using DOM traversal and heuristics to identify article body, removing navigation, ads, and boilerplate. The extension likely uses a content extraction library (similar to Readability or Trafilatura) to identify the primary text content and structure, then sends the cleaned content to Perplexity's backend. Works across diverse page layouts and CMS platforms without manual configuration.

Provides quick access to Perplexity's web search capabilities directly from the browser, allowing users to search across the entire Perplexity index without navigating to Perplexity.ai. The extension opens a search interface within the sidebar or overlay that routes queries to Perplexity's search backend, returning results with AI-generated summaries and citations. Supports search refinement and filtering (if available in Perplexity's API).

Manages conversation and query context within a single browser session, automatically scoping all interactions to the current page unless explicitly changed. The extension tracks the active tab URL and page content, using this as implicit context for all queries and follow-ups. Context is cleared when navigating to a new page or closing the extension, ensuring privacy and preventing cross-page context leakage.
