Glean — Web to Markdown + AI

Extract webpages, PDFs & docs to clean Markdown. Built-in AI chat, smart tables. Docs/Sheets/Slides & more. 100% local.

Copy-paste from the web is messy. Online editors scramble formatting. Long documents only give you what's on screen. Paste into an AI chat and half the tokens are navigation chrome. Glean turns the page you're viewing into clean, structured Markdown — then lets you chat about it inside the extension. No account, no upload. Extraction runs entirely in your browser. RELIABLE EXTRACTION Generic clippers break on modern online editors and canvas-rendered documents. Glean uses dedicated adapters for those cases, and a dual-mode extractor for everyday articles that strips ads and chrome while keeping the writing. Headings, lists, tables, code, and images stay structured so what you save is actually usable. BUILT-IN AI CHAT Summarize, translate, explain, or rewrite without leaving the tab. Connect any OpenAI-compatible API you already use. Stream replies, optionally show reasoning, attach images or files, and keep conversation history per page. Select text in the preview to ask inline, then continue in chat. Or open Ask AI from the popup if you prefer an external chat site. SMART TABLES Detect HTML tables or list/grid layouts, refine the selection interactively, and export as Markdown, CSV, or spreadsheet. Copy a table, or copy it as an image from preview. EVERYDAY TOOLS One click for Markdown. Copy, download, zip with images, or export PDF. Element picker and rectangle select for partial captures. Paste HTML from the clipboard. Live preview with math and diagrams. Editable source with live sync, table of contents, dark mode, and keyboard shortcuts. Many languages. Extraction stays local. FOR AI WORKFLOWS Markdown wastes fewer tokens than raw HTML. A typical article can drop from over 13,000 HTML tokens to under 2,000 in Markdown. Clean input means your models focus on the content — and you can ask about it without leaving the extension. HOW TO USE 1. Open a webpage or online document 2. Click the Glean icon 3. Copy, edit, download, or ask AI Side panel mode adds finer controls: picker, rectangle select, table tools, AI chat, and rendered preview. PRIVACY Extraction is local. AI requests go only to the provider you configure. No account, no analytics, no tracking. Content stays on your device unless you choose to send it to AI.
