Concept Explorer

Concept Explorer

Generate a beautiful, self-contained HTML learning page for any concept the user wants to understand.

Step 1 — Identify the concept

Extract the concept from the user's message. If ambiguous, ask one short clarifying question before proceeding.

Step 2 — Research (run in parallel)

Before writing anything, search for:

1. Real tools / apps using this concept — search "[concept] used in production apps tools 2024 2025"
2. YouTube explainer videos — search "[concept] explained YouTube" — find 2–3 videos with real URLs, prefer channels like 3Blue1Brown, Fireship, Andrej Karpathy, Two Minute Papers, or high-quality tutorials
3. Papers or articles — search "[concept] paper article blog explainer" — find 1–2 links (arXiv, Distill.pub, Towards Data Science, official docs, or a strong blog post)

Only include links you found via search — never fabricate URLs.

Step 3 — Generate the HTML file

Write a single self-contained HTML file directly to D:\AI\Learning\learn-[concept-name].html (kebab-case the concept name).

Page sections (in order)

A. Hero header

• Large concept name, styled as a title
• One-sentence plain-English definition beneath it (no jargon)
• A subtle "study card" feel — not a generic docs page

B. Plain-language explanation

• 3–5 paragraphs, written like you're explaining to a smart non-specialist
• Use at least one real-world analogy that makes the concept tangible
• Break complex ideas into digestible steps
• No bullet points in this section — flowing prose only

C. Real-world tools using this concept

• 3–5 tools or products currently using this concept in production
• For each: name, what it does, and one sentence on how it uses the concept
• Display as styled cards

D. Watch & Read

• 2–3 YouTube videos (title + real URL from search)
• 1–2 papers or articles (title + real URL from search)
• Display as clean link cards with an icon prefix (▶ for video, ◆ for article)
• Never fabricate a link — if search didn't return a good result, omit that slot

E. Build with this — App Ideas

• 2–3 app ideas the user could build using this concept
• Skew strongly toward: architecture, urban design, interior design, real estate, and planning
• Mix of difficulty:
  • At least one "buildable now with Claude" (simple, no infra needed)
  • At least one aspirational (interesting, more complex)
• For each idea: a name, a 2-sentence description, and a difficulty tag (Quick Build / Weekend Project / Ambitious)
• Display as styled cards

Each idea card must have a subtle copy row at the very bottom — muted small text, no buttons, no icons:

<div class="idea-copy-row">
  <span class="copy-cmd" '/software-developer &quot;[Idea Name]: [full 2-sentence description]&quot;')">copy for /software-developer</span>
  <span class="copy-sep">·</span>
  <span class="copy-cmd" '/startup-analyzer &quot;[Idea Name]: [full 2-sentence description]&quot;')">copy for /startup-analyzer</span>
</div>

Replace [Idea Name] and [full 2-sentence description] with the actual content. Escape inner quotes as " in HTML attributes.

JavaScript — one function, placed in a <script> tag just before </body>:

function copyCmd(el, text) {
  navigator.clipboard.writeText(text).then(() => {
    const orig = el.textContent;
    el.textContent = 'copied ✓';
    el.style.color = '#4A7C6F';
    setTimeout(() => { el.textContent = orig; el.style.color = ''; }, 2000);
  });
}

CSS for the copy row — add to <style>:

.idea-copy-row {
  margin-top: 0.9rem;
  padding-top: 0.6rem;
  border-top: 1px solid #e8e2d9;
  display: flex;
  align-items: center;
  gap: 0.5rem;
}
.copy-cmd {
  font-size: 0.68rem;
  color: #c0b8ae;
  cursor: pointer;
  user-select: none;
  transition: color 0.15s;
  letter-spacing: 0.01em;
}
.copy-cmd:hover { color: #4A7C6F; }
.copy-sep {
  font-size: 0.68rem;
  color: #d8d0c8;
}

Design rules

Colour palette — use exactly these:

Typography:

• Font: DM Sans — load via <link rel="preconnect" href="https://fonts.googleapis.com"> and <link href="https://fonts.googleapis.com/css2?family=DM+Sans:ital,opsz,wght@0,9..40,300;0,9..40,400;0,9..40,500;0,9..40,600;1,9..40,400&display=swap" rel="stylesheet"> in <head>. Fallback stack: font-family: 'DM Sans', 'Segoe UI', system-ui, sans-serif
• Hero title: large, bold (600), #1B3A2D
• Section labels: small caps or uppercase tracking, #4A7C6F
• Body text: comfortable line-height (1.7), weight 400, #1B3A2D

Layout:

• Max content width: 860px, centred
• Generous padding — this should feel like opening a well-designed magazine page
• Cards in a 2-column CSS grid on wider screens, 1-column on narrow
• Difficulty tags as small inline pills: Quick Build = #4A7C6F, Weekend Project = #E8724A, Ambitious = #1B3A2D

HTML file rules:

• All CSS in <style> in <head> (Google Fonts link is the only external dependency — acceptable)
• Minimal inline JavaScript allowed only for the clipboard copy function — one copyCmd function in a <script> tag before </body>, nothing else
• Must render correctly in any modern browser

Step 4 — Push to GitHub

After writing the HTML file, run these git commands via Bash:

cd D:\AI\Learning
git add learn-[concept-name].html
git commit -m "Add: learn-[concept-name].html"
git push

After pushing

Tell the user:

• The filename
• One sentence on the analogy you used
• Confirm the file was pushed to GitHub

Nothing more.
