There’s a very specific feeling you get when you land on a website and think, “Okay… this is clean.”
Not flashy. Not loud. Just… solid. The spacing feels intentional. The typography doesn’t fight itself. The buttons feel like they belong, and suddenly you’re curious—not as a user, but as a builder.
So you do what we all do. Right-click and inspect.
Five minutes later, you’re ten divs deep, staring at a cascade of inherited styles, wondering where that spacing is actually coming from.
Is it margin? Padding? A utility class? A parent container you haven’t scrolled far enough to find yet?
Yeah. That moment 😬
This post is about that frustration — and how it led me to build Design Research Insight Assistant (DIRA), a Chrome extension that helps turn “this site looks nice” into actual, reusable design insight.
Not screenshots. Not vibes or guesswork.
Real structure. Real data. Right inside the browser.
Why Design Research on the Web Is Still Weirdly Painful
Here’s the thing: the web is the largest design system repository we have.
Every landing page, marketing site, SaaS dashboard, blog, and checkout flow is a living, breathing interface someone designed, debated, tested, and shipped.
However, extracting anything meaningful from those interfaces is still oddly manual.
Most of us rely on some combination of:
- Screenshots saved into a “design inspo” folder
- Random Figma pages labeled “Reference – Buttons??”
- Notes that say things like “Nice spacing here” (cool, very helpful 🙃)
- DevTools archaeology sessions that end in fatigue
None of that is terrible, but none of it scales either.
Screenshots capture appearance, not structure. Notes lose context fast. DevTools, while powerful, aren’t optimized for design questions.
DevTools answer:
- “What is this element’s computed font-size?”
Designers are often asking:
- “What font sizes does this site consistently use?”
- “Is there a spacing system here, or is this vibes-based?”
- “How many CTA styles does this page actually introduce?”
Those are different questions with a gap that DIRA was born to fill.
What DIRA Actually Is (and What It Very Intentionally Isn’t)
DIRA stands for Design Research Insight Assistant, and at its core, it’s a Chrome extension for designers who want to study real interfaces—not just admire them.
You click the extension.
You analyze the current page.
A side panel slides in with a structured breakdown of what’s going on visually and structurally.
That’s it. No accounts or uploads. No magic cloud AI doing questionable things behind the scenes.
What DIRA is:
- A fast way to extract design signals from live websites
- A research tool for UI, UX, product, and visual designers
- A bridge between visual intuition and implementation reality
What DIRA is not:
- A replacement for DevTools
- A full accessibility auditing tool
- A “press one button and steal the design” machine
It doesn’t aim for perfection. It aims for usefulness.
And honestly? That distinction matters a lot.

Moving Beyond “Inspect Element” Without Throwing It Away
I want to be clear about something upfront: Inspect Element isn’t the enemy.
I still use DevTools daily. You probably do too.
However, manual inspection breaks down when you’re trying to understand patterns, not individual values.
Let’s say you inspect one heading and see font-size: 32px.
Cool 😎
But what you don’t know yet:
- Is that used anywhere else?
- Is 32px part of a type scale, or a one-off?
- How does it relate to the rest of the page?
To answer that manually, you’d need to:
- Inspect multiple elements
- Track values externally
- Look for repetition yourself
That’s cognitive load you don’t need.
DIRA’s approach is simple:
- Scan the DOM
- Collect relevant design signals
- Group and summarize them in a way that designers can reason about
Instead of “here’s one font-size”, you get:
- A distribution of font sizes
- Frequency-based color palettes
- Common spacing values across the page
It doesn’t replace thinking. It supports it 🤝
The Core Idea: Structure Beats Screenshots
While screenshots are great for mood, composition, and visual reference, they’re terrible for comparison, recall, and system-level understanding.
That’s why DIRA saves analyzed pages as Inspiration Cards—not images, but structured research artifacts.
Each card can include:
- Color usage data
- Typography signals
- Layout indicators
- Spacing heuristics
- CTA patterns
- Asset samples
- Contrast snapshots
And you can tag them, add notes, or compare them later.
This turns “I saw this cool site once” into something you can actually work with weeks later.
What DIRA Analyzes Today (v1.0.0)
When you click the extension icon, DIRA automatically analyzes the page, pulling together several focused views of the interface.
Tip 👀
Click the refresh icon on the top right corner of the DIRA sidebar to either analyze a new page or refresh an analysis on the current page.
Color Palette (Frequency-Based)
Instead of dumping every color found in the DOM, DIRA:
- Samples rendered colors
- Groups them by frequency
- Surfaces dominant colors first
This helps answer questions like:
- “What colors does this page actually rely on?”
- “Are accent colors rare or overused?”
Typography Signals
DIRA looks at:
- Fonts in use
- Font sizes
- Rough hierarchy hints
It’s not doing semantic analysis of intent, but it does help reveal whether a page is working off a tight type system or an ad-hoc one.
Layout Structure Signals
Rather than pixel-perfect measurements, DIRA detects structural patterns:
- Headers
- Navigation areas
- Hero sections
- Card-like groupings
- Grid-like layouts
This is especially helpful when you’re studying landing pages or content-heavy sites.
Spacing Heuristics
Spacing is one of those things designers feel before they can articulate.
DIRA samples margins and paddings across elements and surfaces common values. This helps answer:
- “Is there a consistent spacing rhythm here?”
- “Are we seeing multiples of a base unit?”
Calls to Action
Buttons and CTA-like links are identified and grouped so you can see:
- How many CTA styles are present
- Where emphasis is placed
- Whether the page feels focused or scattered
Asset Sampling
Image thumbnails give you quick insight into:
- Visual density
- Illustration vs photography
- Repetition of asset styles
Basic Contrast Sampling
This one’s intentionally labeled basic.
DIRA samples foreground/background contrast to raise early accessibility awareness—not to replace proper audits.

Saving Research, Not Just References
Once a page is analyzed, you can save it as an Inspiration Card.
This is where things get interesting.
Instead of just bookmarking a URL, you now have:
- Structured data tied to that page
- Your own notes and tags
- A snapshot of the design signals as they existed when you analyzed it
Everything is stored locally using chrome.storage.local.
Note 👇
This was a deliberate choice to keep it real with the no sync, no accounts, no tracking objective. If it’s on your machine, it’s yours 💁♀️ That said, future updates may introduce additional storage options for those wishing to auto-save and collaborate on shared spaces. Let me know your thoughts!

Side-by-Side Comparison: Where Patterns Really Show Up
One of my favorite parts of DIRA is the comparison view.
Pick two saved cards and compare them side by side. Suddenly you’re not asking: “Which one do I like more?”
You’re asking:
- Which one uses fewer colors?
- Which one relies on tighter spacing?
- Which one introduces more CTA styles?
- Which one feels more visually complex — and why?
This is incredibly useful for:
- Competitive analysis
- Studying design philosophy differences
- Sanity-checking your own work against references
And yes, comparing obvious competitors (think Airbnb vs Booking.com) is interesting 😉
Real Workflow Wins (Not Theoretical Ones)
All this information is great, but let’s talk about where this actually helps in day-to-day work.
Competitive Analysis Without Losing Your Mind
Instead of: Screenshot → paste → annotate → forget
You can:
- Analyze several competitors quickly
- Save them with tags
- Compare patterns objectively
Ten competitors in ten minutes is realistic.
Design Consistency Checks
This surprised me (in a good way).
DIRA is handy when you’re checking your own staging or production site.
In what way? Well, it helps answer:
- Are new pages introducing new spacing values?
- Are CTAs drifting stylistically?
- Is typography staying consistent?
It’s not a replacement for Figma, but it’s a great reality check.
Designer–Developer Conversations Get Easier
DIRA helps ground conversations in shared facts:
- Designers see patterns
- Developers see CSS-level signals
Less “this feels off.”
More “we’ve introduced three new spacing values here.”
That’s a win for everyone!
This one matters a lot because there’s no way I’m the only dev who’s been in a conversation with a designer, and it feels like we’re speaking drastically different languages.
Under the Hood: The Tricky Parts Nobody Sees
Building DIRA wasn’t just slapping a content script together and calling it a day.
A few challenges were, let’s say, character-building 😅
The Transparent Background Problem
Contrast checking sounds simple until you remember:
- Many elements have transparent backgrounds
- Colors are often inherited several layers up
Naive contrast checks fail hard here.
The solution?
A recursive parent traversal algorithm that walks up the DOM until it finds the actual rendered background.
Not glamorous. Very necessary.
Restricted Pages and Extension Limits
Chrome extensions don’t run everywhere.
Pages like:
chrome://- Internal system URLs
DIRA detects restricted environments and fails gracefully, with clear feedback instead of silent errors.
Content Script Race Conditions
Side panels and content scripts don’t always load in sync.
Sometimes the panel is ready before the script exists.
To handle this, DIRA uses a small messaging layer that:
- Checks for script presence
- Injects when needed
- Retries safely
It’s not fancy, but it is reliable. And reliability matters more.
The Design Philosophy Behind DIRA
There are a few principles guiding this project that help shape a lot of the logical architecture that makes the extension.
Local-First, Always
All data stays on your machine.
This means: no uploads, tracking, or accounts.
It’s a great start for an MVP version like that of DIRA because it significantly reduces complex overhead.
Useful Signals Over Perfect Detection
DIRA doesn’t claim to be 100% accurate.
It claims to be helpful.
That’s an important difference.
Note: This tool is AI-free largely to keep in line with the local-first principle. AI integration can enhance the design analysis and it’s very possible future versions will have AI as an option.
Built For Iteration
Saved cards, tags, notes, and comparisons.
Need I say more?
This tool is meant to be revisited, not used once and forgotten.
What I Learned Building This
A few takeaways that surprised me:
- The web already contains an absurd amount of design knowledge—it’s just poorly surfaced
- Designers don’t need more inspiration; they need better research tools
- Structure beats vibes when you’re trying to learn and reuse patterns
- Browser extensions are wildly underrated for design workflows
Most importantly: Design research doesn’t have to be slow or vague.
Where DIRA Might Go Next
This is very much v1 energy.
Some future directions I’m excited about:
- Smarter hierarchy inference
- Better pattern grouping
- Figma integration (copying styles as tokens or CSS 👀)
- AI (cloud and local) provider integration
- Optional backup and save on cloud providers like Google Drive
No promises. Just possibilities.
It’s A Wrap
If you’ve ever stared at a website and thought, “I wish I could understand this faster,” that’s exactly why DIRA exists.
It’s not about copying designs. It’s about learning from them—systematically, respectfully, and efficiently.
If you try it and have thoughts, questions, or “what if it also did this?” ideas, I genuinely want to hear them.
Thanks for hanging out with me on this one.
’Till next time 👋
