<span class="label">Overview</span>
<h2>What is vxrtx?</h2>
<p class="lead">
vxrtx is a Chrome side panel extension that uses AI to organize tabs and bookmarks.
It detects stale tabs, finds duplicates, suggests intelligent groupings, and lets users
lock folders and groups they want to protect from reorganization.
</p>
<p>
The extension supports five AI providers across three privacy tiers — from fully local
inference with no network calls to full cloud context for maximum quality. A snapshot system
provides safety nets with persistent history, import/export, and granular restore. The entire
release pipeline is automated with CI gates, Release Please versioning, and Chrome Web Store
draft uploads.

<span class="label">Privacy</span>
<h2>Three Tiers, One Toggle</h2>
<p>
Privacy isn't a checkbox — it's a spectrum. vxrtx lets users choose exactly how much
data leaves their machine, with clear labeling and instant switching between tiers.
</p>
<div class="tier-grid">
<div class="tier-card tier-secure">
<div class="tier-name">Secure</div>
<div class="tier-tagline">Nothing leaves your machine</div>
<p>Use rule-based grouping, a local Ollama instance, or Chrome's built-in Gemini Nano. Zero network calls.</p>
</div>
<div class="tier-card tier-relaxed">
<div class="tier-name">Relaxed</div>
<div class="tier-tagline">Cloud AI, minimal data</div>
<p>Send tab and bookmark titles to your chosen cloud AI — but never URLs. Enough context for smart grouping.</p>
</div>
<div class="tier-card tier-yolo">
<div class="tier-name">YOLO</div>
<div class="tier-tagline">Full context, maximum quality</div>
<p>Send titles, URLs, and timestamps. The AI sees everything for the best results. Your API key, your choice.</p>
</div>
</div>
<p class="text-dim" style="font-size: 13px;">
The tier system is enforced at the prompt engineering layer — each tier has its own prompt
template that controls exactly what data is included. Switching tiers doesn't change the AI
model, just the context window. API keys are stored locally in Chrome storage and never
transmitted to vxrtx servers.
</p>
</div>
</section>
<!-- ═══════════════════════════════════════════ AI PROVIDERS ═══ -->
<section>
<div class="container narrow">
<span class="label">AI Providers</span>
<h2>Use Whatever Works</h2>
<p>
vxrtx supports five AI providers spanning cloud, local, on-device, and no-AI options.
Users bring their own API keys — there's no shared key, no middleman, no subscription.
</p>
<div class="provider-list">
<div class="provider-item">
<span class="provider-name">OpenRouter</span>
<span class="provider-desc">Unified gateway to Claude, GPT-4o, Llama, Gemini, and 100+ models with one API key. Default provider for cloud tiers.</span>
</div>
<div class="provider-item">
<span class="provider-name">Direct API</span>
<span class="provider-desc">Bring your own Anthropic or OpenAI key for direct access without a middleman.</span>
</div>
<div class="provider-item">
<span class="provider-name">Ollama</span>
<span class="provider-desc">Run Llama 3.2, Mistral, Gemma 2, or Phi-3 locally. 100% private, no API key needed.</span>
</div>
<div class="provider-item">
<span class="provider-name">Chrome Built-in AI</span>
<span class="provider-desc">Gemini Nano on-device via Chrome 138+ Prompt API. Fully offline, no downloads, no subscription.</span>
</div>
<div class="provider-item">
<span class="provider-name">Rules</span>
<span class="provider-desc">Fast domain-based grouping with zero AI. Instant results, no network, no model — just pattern matching.</span>
</div>
</div>
<p class="text-dim" style="font-size: 13px;">
The provider architecture uses a shared interface with per-provider adapters. Smart model
routing selects between fast and capable models based on item count. Timeout scaling adapts
to collection size. All providers share the same prompt composition pipeline with modular
system prompts and few-shot examples.

<h2>Color Evolution</h2>
<p>
The brand identity went through three distinct color phases,
each reflecting a shift in the product's personality as it matured.
</p>
<div class="color-evolution">
<div class="color-chip">
<div class="swatch" style="background: #6366f1;"></div>

<div class="color-hex">#20fc8f</div>
</div>
</div>
</div>
<p class="text-dim" style="font-size: 13px;">
Purple felt generic and safe. Cyan added energy but skewed too clinical.
Green landed as the final direction — electric, organic, signaling growth and organization
without the coldness of blue tones. The full brand palette includes
<span style="color: var(--indigo);">indigo</span> and
<span style="color: var(--pink);">pink</span> as semantic accents for the
Relaxed and YOLO tiers, with coal-black (#111313) as the constant dark canvas.

<h2>From Prototype to Product</h2>
<p>
The "Quiet Precision" design pass transformed the UI from a functional prototype into
a cohesive product. No features changed — only the visual layer was elevated.
</p>
<div class="callout">
<p>
<strong style="color: var(--brand);">Design philosophy:</strong>
The tool organizes chaos into order. The UI embodies that ethos — dense with
information when needed, beautifully minimal when idle. Every surface intentional,
every interaction grounded.
</p>
</div>
<h3>Key Design Decisions</h3>
<div class="feature-grid" style="margin-top: 16px;">
<div class="feature-card">
<h4>Outfit Typeface</h4>
<p>Geometric, confident, distinctive at every size. Replaces system defaults with a font that conveys precision.</p>
</div>
<div class="feature-card">
<h4>SVG Icon System</h4>
<p>All emoji replaced with crisp, consistent inline SVGs that scale perfectly and match the brand aesthetic.</p>
</div>
<div class="feature-card">
<h4>Glowing Accents</h4>
<p>CTA buttons and active nav indicators use box-shadow glow effects for a neon-on-dark signature.</p>
</div>
<div class="feature-card">
<h4>Custom Form Controls</h4>
<p>Range sliders with branded thumb glow, custom checkboxes, refined input focus states — all via CSS.</p>
</div>
<div class="feature-card">
<h4>Semantic Color</h4>
<p>Green for primary actions, indigo for relaxed tier, pink for YOLO, amber for undo/restore, red for destructive.</p>
</div>
<div class="feature-card">
<h4>Noise Texture</h4>
<p>Subtle SVG fractal noise at 1.8% opacity adds analog depth to the digital surface.</p>

<!-- ═══════════════════════════════════════════ PATTERNS ═══ -->
<section>
<div class="container narrow">
<span class="label">Patterns</span>
<h2>Design System</h2>
<p>
A consistent set of patterns keeps the interface cohesive across all four screens
and dozens of states.
</p>
<h3 style="margin-top: 32px;">State Machine Pattern</h3>
<p class="text-dim" style="font-size: 13px;">
Both organizers follow an identical five-state workflow:
<strong style="color: var(--zinc-300);">idle → loading → preview → applying → done</strong>.
This gives users a predictable mental model regardless of whether they're organizing
tabs or bookmarks.
</p>
<h3 style="margin-top: 32px;">Progressive Disclosure</h3>
<p class="text-dim" style="font-size: 13px;">
Complexity is revealed only when needed. Settings shows a minimal interface for the Secure tier,
expanding to provider selection and API configuration only when users opt into cloud AI.
The Bookmarks screen uses a mode menu rather than cramming all four tools into a single view.
</p>
<h3 style="margin-top: 32px;">Safety-First Operations</h3>
<p class="text-dim" style="font-size: 13px;">
Every destructive action has a safety net. Organize operations create automatic snapshots.
Delete requires confirmation. Applied changes can be undone. Folders and groups can be locked
to exclude them from AI reorganization entirely.
</p>
<h3 style="margin-top: 32px;">Button Hierarchy</h3>
<div class="tech-pills" style="margin-top: 12px;">
<span class="tech-pill" style="background: #0acd72; color: #111313; border-color: #0acd72; font-family: var(--font); font-weight: 600;">Primary CTA</span>
<span class="tech-pill" style="border-color: var(--zinc-700); color: var(--zinc-300); font-family: var(--font); font-weight: 500;">Secondary</span>
<span class="tech-pill" style="border-color: #b45309; color: #fcd34d; font-family: var(--font); font-weight: 500;">Undo / Restore</span>
<span class="tech-pill" style="border-color: #b91c1c; color: #fca5a5; font-family: var(--font); font-weight: 500;">Destructive</span>
<span class="tech-pill" style="border: none; color: var(--zinc-500); font-family: var(--font);">Tertiary / Link</span>

<!-- ═══════════════════════════════════════════ REFLECTIONS ═══ -->
<section style="border-bottom: none;">
<div class="container narrow">
<span class="label">Reflections</span>
<h2>What Worked</h2>
<p>
Establishing a consistent state machine pattern early paid dividends — every new feature
slots into the existing idle→loading→preview→done flow without inventing
new paradigms. The tab and bookmark organizers are architecturally identical despite
completely different Chrome APIs.
</p>
<p>
The three-phase brand evolution was unplanned but beneficial. Each color shift forced a
re-evaluation of the entire interface, revealing places where the design relied too heavily
on accent color versus structural contrast. The final palette — green primary, indigo and
pink as semantic accents — gives each privacy tier its own visual identity.
</p>
<p>
Separating design polish from feature work prevented premature refinement from slowing
development. The "Quiet Precision" pass happened only after all four screens were functional,
making it possible to apply consistent treatment across the entire interface in one sweep.
</p>
<div class="callout" style="margin-top: 40px;">
<p>
<strong style="color: var(--brand);">Key takeaway:</strong>
In a side panel extension, every pixel competes for attention in a 400px-wide strip.
The most impactful design decisions are about what to <em>remove</em> — reducing visual
noise, tightening spacing, and replacing emoji with purposeful iconography. Restraint
is the hardest part of designing for constrained surfaces.
