xTil

About

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.

────────────────────────────────────────

SMART GENRE DETECTION
xTil automatically identifies what you're reading — news article, tutorial, academic paper, movie, comedy special, business report, legal document, and more — then tailors the summary with genre-specific sections. News gets fact-checking and timelines. Tutorials get step-by-step breakdowns. Fiction gets cast info, spoiler-protected plot summaries, and review scores fetched via web search. Each genre brings a different expert perspective.

────────────────────────────────────────

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.

────────────────────────────────────────

WORKS EVERYWHERE YOU READ
xTil adapts to the page you're on:
• Articles & PDFs — Papers, reports, and documents with figure extraction
• Video platforms — Transcript-based summaries with clickable timestamps, show metadata, and maturity ratings
• Code hosting — PRs, issues, code files, repos, commits, and releases
• Social media — Posts, threads, nested comments, and engagement metrics
…and many more. Full list of supported platforms at github.com/aitkn/xtil

AUTO-GENERATED DIAGRAMS & IMAGE ANALYSIS
xTil generates diagrams that visualize the content's structure — flowcharts, timelines, data charts, 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. Use web search to fact-check claims against live sources. Chat responses are structured with the same quality as the initial summary.

────────────────────────────────────────
