Before & After Reveal Tool

after a minute or so scraping away the leaves

In a world of AI take the photos with the EXIF location settings on that way you can showcase that you just did, and you did not just ask AI to remove all the leaves from the photo.

Of course there could be something more impressive than just seeing the leaves gone from covering a drain.

Traditional carousels (like carousel modes in SmartSlider 3, Slick, or Swiper) have notoriously poor engagement data across web usability studies:

The “Banner Blindness” Problem: Users treat auto-rotating carousels as banner ads and scroll straight past them. Jakob Nielsen’s group and the Notre Dame web studies famously showed that auto-advancing slides have click-through rates often below 1%, with nearly all clicks going only to the very first slide.
Loss of Control: When a slide moves automatically while someone is trying to read or inspect it, it causes immediate frustration. If it doesn’t move automatically, users rarely click pagination dots or arrows because they assume there’s nothing critical on slide 2.

A before-and-after reveal slider solves those exact friction points:

1. Instant Cognitive Processing

Text requires parsing and mental modeling; an overlaid visual comparison is processed in milliseconds. When comparing:

Old historical maps vs. modern satellite imagery
Dental, cosmetic, or landscaping transformations
Website redesigns or photo restorations

Placing two pictures side-by-side forces the eye to jump back and forth across a gap to locate differences. An overlay slider aligns spatial coordinates 1:1, so the brain detects change instantly at the dividing boundary.

2. High “Haptic” Micro-Interactivity

Because it doesn’t auto-play, it requires an intentional scrub or swipe:

On mobile: Swiping horizontally directly under the thumb feels native and tactile (like peeling back a layer).
On desktop: Mouse movement tracks smoothly.
Dwell time boost: When users interact with a physical drag handle, session duration increases, which sends positive engagement signals for SEO and visitor conversion.

3. Lightness & Code Overhead

Tools like SmartSlider 3 are comprehensive suites that package complex transition engines, layered animation queues, touch handlers, and CSS frameworks (often 100kB+ of script overhead).

By contrast, a before-and-after reveal tool needs only:

Two stacked images (one absolutely positioned inside a container with overflow: hidden or CSS clip-path).
A simple <input type="range"> or a tiny 2KB–5KB touch/mouse event listener to update the width percentage.
This keeps Largest Contentful Paint (LCP) and Total Blocking Time (TBT) lean compared to full-blown slider suites.

High “Haptic” Micro-Interactivity Means…

Describes the feeling that you are physically touching and manipulating digital objects on the screen rather than just looking at them.

Broken down into plain English:

1. The “Haptic” Part (Touch & Physics)

What it means: “Haptic” refers to the sense of touch. On modern smartphones, hardware engines create tiny physical clicks, vibrations, or resistances when you toggle a switch, scroll a date wheel, or pull down to refresh.
Why it matters for an image slider: When a user puts their thumb on that divider bar and slides it across, the screen responds 1:1 in real time. Because the boundary moves directly under their thumb at the exact speed of their hand, the brain perceives it as tactile control—like physically wiping condensation off glass or peeling back a layer of paper—rather than passively watching a video or an automated slideshow.

2. The “Micro-Interactivity” Part (Tiny, Frictionless Actions)

What it means: A “macro-interaction” is filling out a multi-step contact form, creating an account, or going through a shopping cart checkout. It takes conscious mental effort.
A “micro-interaction” is a single, effortless, self-contained action:
- Tapping a “heart” button on Instagram and seeing it pop.
- Toggling dark mode on a site and watching the colors invert instantly.
- Dragging a slider bar left and right.
Why it matters: It requires zero cognitive load. The user doesn’t have to read instructions, decide between three menu options, or wait for a page reload. They simply touch it to see what happens, and the visual feedback is instant.

The Psychological Payoff: Why It Works

When people visit a website, their default behavior is passive: scan headers, scroll past blocks of text, ignore auto-advancing carousels.

The moment a user scrubs a reveal slider, two things happen:

Ownership & Curiosity: The user is no longer a passive spectator waiting for a slide to change; they are actively controlling the reveal. It taps into the same curiosity loop as a scratch-off lottery ticket.
Engagement Depth: Even two or three seconds spent sliding back and forth anchors their attention. They aren’t skimming anymore—they are scrutinizing the differences between the two images.

In short: strip away the design buzzwords, and it simply means giving the visitor a physical toy to play with on the page that rewards their touch immediately.
