Turn any webpage into clean Markdown. 20 site-specific extractors. Images, frontmatter, Obsidian-ready. One click. No account needed. Stop copy-pasting into Obsidian and spending 10 minutes cleaning up broken formatting. Markforge converts any webpage to clean, structured Markdown in one click, with proper headings, images saved locally, and YAML frontmatter generated automatically. Unlike generic web clippers, Markforge has a dedicated extractor for each supported site. Reddit threads don't look like YouTube transcripts, and ChatGPT conversations don't look like Wikipedia articles. Each site gets its own extraction logic, tuned to produce the cleanest possible Markdown output. SUPPORTED SITES (18+) Social & Forums Reddit — posts + comments with threaded nesting Twitter/X — full threads and long-form articles LinkedIn — posts and Pulse articles Hacker News — posts with comment trees AI Conversations ChatGPT — full conversation export with user/assistant turns Claude — conversation threads with deduplication Google Gemini — interleaved queries and responses Grok — complete chat history Knowledge & Research Wikipedia — clean article extraction, multi-language arXiv — papers with authors, abstract, DOI, references ResearchGate — publications with figures and citations Stack Overflow — questions, accepted answers, votes Publishing Medium — articles with paywall detection Substack — newsletters with embedded content GitHub — code files (raw) and README/repo pages Email & Search Gmail — emails with participant directory Google Search — search results with snippets Any other website — intelligent fallback extractor that finds the main content automatically. KEY FEATURES Clean Markdown Output Every extraction produces properly formatted Markdown: ATX headings, fenced code blocks, inline links, clean list markers. No leftover HTML, no broken formatting, no UI artifacts. Local Image Download Images are fetched and saved alongside your Markdown file in an /images folder. No broken links, no reliance on remote servers. Works even with CORS-protected images through an intelligent 3-step fallback system. YAML Frontmatter Automatically generates frontmatter with title, author, date, source URL, description, and tags. Fully customizable template — add, remove, or reorder any field. Obsidian Integration Native wikilink syntax for images (![[image.png]]), customizable frontmatter, and direct file saving to your vault folder. Clip Selection Mode Don't need the full page? Activate clip mode, click any element on the page, and Markforge extracts just that section. Filename Templates Customize your filenames with variables: {title}, {author}, {date}, {site}, {domain}. Every file is named exactly how you want it. Strategy Options Toggle site-specific features per platform — include Reddit comments, Twitter replies, Stack Overflow answers, YouTube timestamps, or Gmail quoted text. Content Filtering Strip tracking parameters from URLs, remove elements by CSS selector, filter small images. Keep only what matters. Token Counter Built-in character, word, and token counter — useful when preparing content for LLM context windows. HOW IT WORKS 1. Navigate to any webpage 2.
