xTil

Extract the signal, distill the insight. AI summaries of articles, PDFs, videos & PRs with diagrams, chat and Notion export.

xTil (pronounced "ex-til", from extract + distill) turns any web page into structured, actionable knowledge — not just a summary, but a full breakdown you can refine, discuss, and share. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Stop reading 3,000-word articles. Get structured insights in seconds. xTil turns any web page, PDF, video, or PR into a multi-section analysis — key takeaways, fact-checks, diagrams, and more. Then refine with chat and export anywhere. ──────────────────────────────────────── WHAT YOU GET Every page produces a structured breakdown: concise overview, key takeaways with bold labels, notable quotes with original language preserved, a fact-check grading claims as verified/contested/unverifiable, pros & cons, and a conclusion. LaTeX math renders beautifully — perfect for academic papers. Choose between brief, standard, or detailed analysis — xTil automatically scales the depth to match the content. ──────────────────────────────────────── PLATFORM AWARENESS Every platform gets special treatment: • PDFs — Summarize academic papers, reports, and any PDF opened in Chrome, with figure extraction • YouTube — Full transcript summary with clickable timestamp links • GitHub — Six modes: PRs, issues, code files, repos, commits, and releases • Reddit — Complete threads with nested comments, scores, and engagement metrics • Twitter/X — Thread reconstruction with engagement data and notable replies • Google Docs — Reads content directly from your authenticated session • Facebook — Extracts posts from feed overlays with reaction counts • LinkedIn — Summarize posts from feed or direct URLs with engagement metrics • Gmail — Summarize emails and threaded conversations from the reading pane ──────────────────────────────────────── AUTO-GENERATED DIAGRAMS & IMAGE ANALYSIS xTil generates Mermaid diagrams that visualize the content's structure — flowcharts, timelines, and more, with automatic light/dark theme support. Pages with images get vision-powered analysis: charts, screenshots, and infographics are read and woven into the summary. ──────────────────────────────────────── BRING YOUR OWN KEY No subscription. Use the AI you already pay for. Works with all major LLM providers and any OpenAI-compatible endpoint, including self-hosted models. xTil auto-discovers available models and probes vision capability — image analysis just works. ──────────────────────────────────────── REFINE WITH CHAT Ask follow-up questions, request deeper analysis, or explore specific sections.
