VS Code Extension · 3 Free Languages · 10 with Pro · 600+ Keywords

Read code with your
whole brain.

Moji adds visual cues to code keywords—reducing cognitive load, boosting pattern recognition, and making code easier to read at a glance.

Watch Moji transform your code

See how emoji overlays instantly make code easier to scan—without changing a single character in your files.

Code that speaks to your visual cortex

Your source code stays untouched. Moji overlays intuitive visual symbols next to keywords, giving your brain a second channel for meaning.

Without Moji
JavaScript
async function fetchUser(id) {
  try {
    const res = await fetch(`/api/${id}`);
    if (!res.ok) {
      throw new Error('Not found');
    }
    return await res.json();
  } catch (err) {
    console.log(err);
  }
}
With Moji
JavaScript + MojiCode-Pro
🚀 asyncfunction fetchUser(id) {
  🤞 try {
    🔒 const res = ⏳ await fetch(`/api/${id}`);
    ❓ if (!res.ok) {

    }
    🔙 returnawait res.json();
  } 🥅 catch (err) {
    console.log(err);
  }
}
Python

SQL

Your brain wasn't designed to read code

Every keyword demands a mental translation. That translation layer drains the working memory you need for understanding logic, state, and intent.

  • 🚫 return → mentally decode as "send a value back"
  • 🚫 async → mentally decode as "non-blocking operation"
  • 🚫 SELECT → mentally decode as "query data"
  • Visual symbols are processed instantly by the brain

Your Brain's Strengths

Visual patterns
Image processing
Emotional recall
Text token decoding

Built for real workflows

A cognitive overlay that enhances how you see code—without changing a single byte of your source files.

🌐

Up to 10 Languages

Free: JavaScript, HTML, and CSS. Pro: adds TypeScript, Python, C, C++, C#, Java, and SQL—600+ keyword mappings total.

🛡️

Zero Side Effects

Source code is never modified. Emojis are rendered as visual overlays only. Your files stay production-safe.

⚙️

Fully Configurable

Toggle the entire extension or fine-tune individual emojis per language through the built-in settings panel.

🔄

Two Display Modes

Overlay shows emojis alongside keywords. Replace swaps the keyword text with its emoji visually.

Instant Toggle

One command to turn it on or off. No restart required. Works the moment you open a supported file.

🤝

Team-Safe

Collaborators won't see emojis unless they install it themselves. Zero impact on version control or linting.

3 free languages. 10 with Pro.

Install the Extension

Search "Moji" in the VS Code marketplace and click Install. That's it.

Open a Supported File

Open any JavaScript, Python, SQL, C#, or other supported language file. Emojis render automatically.

Read Code Faster

Your brain processes visual symbols instantly. Spot returns, loops, awaits, and errors at a glance.

"Programming feels hard because written code forces your brain to operate against its natural strengths."
— The Moji Philosopher

Common questions

Is Moji private?
100%. Always. Forever. We validate your license. Nothing else.
Does this change my source code?
No. The extension only affects how you see code in VS Code. Your files remain completely unchanged. This is a visual overlay, not a syntax transformation.
Will this break my workflow?
No. Your code stays standard source code. Linting, formatting, version control, and every other tool works exactly as before.
Can collaborators see the emojis?
Only if they also have Moji-Pro installed. Source files are never affected, so collaboration is seamless.
Why emojis instead of icons?
Emojis are universal (no asset loading), instantly recognizable, emotionally tagged (stronger recall), and lightweight with zero performance impact.
Can I disable specific emojis?
Yes. Open the Settings panel via the Moji: Settings command to toggle individual emojis on or off for each language.
Is there scientific basis for this?
Yes. The cognitive science behind visual processing, dual coding theory, and reduced working memory load is well-established. MojiCode-Pro applies those principles to code reading.
