How it works

Three steps. Done.

CodeCompose lives in Gmail's right-click menu. No new tabs, no external tools, no copying and pasting.

1

Write or paste code

Type or paste your code directly into a Gmail compose window like you normally would.

2

Select and right-click

Highlight the code, right-click, and choose Insert Code Block from the context menu.

3

Pick language and insert

CodeCompose detects the language automatically. Preview it, tweak if needed, then hit Insert.

FAQ

Common questions.

Everything you need to know before installing.

Is there a free trial? ⌄
Yes. Junior Dev includes a 3-day free trial — no commitment required. If you cancel within 3 days you won't be charged anything. After the trial it's $0.99/mo and you can cancel anytime from your Lemon Squeezy customer portal or directly from the CodeCompose settings page.
Does CodeCompose read my emails? ⌄
No. CodeCompose only activates when you right-click selected text in the Gmail compose window. It never reads, stores, or transmits email content. The only external call it makes is a daily license key check with Lemon Squeezy to verify paid subscriptions.
Does the code block look good to the recipient? ⌄
Yes. Code blocks are inserted as email-safe HTML with fully inline styles — no external stylesheets, no web fonts. They render correctly in Gmail, Outlook, Apple Mail, and most other major clients.
Which languages are supported? ⌄
19 total. Free: JavaScript, JSON, Python. Junior Dev adds TypeScript, SQL, HTML, CSS, Java, PHP, Ruby, Shell/Bash, and YAML. Senior Dev adds Go, Rust, Kotlin, Swift, C++, and XML. More languages are coming to Senior Dev.
How do I activate my license after purchasing? ⌄
After checkout, Lemon Squeezy will email you a license key. In Chrome, click the CodeCompose icon in your toolbar → Open Settings → paste your key into the license field → click Activate. Your plan upgrades instantly. You can also reach Settings by right-clicking in Gmail → Insert Code Block → Open Settings.
Can I cancel my subscription? ⌄
Yes, at any time through your Lemon Squeezy customer portal. You can also deactivate your license key directly from the CodeCompose settings page inside Chrome.
What happens if I cancel? ⌄
Your account automatically reverts to the Free tier. You keep the extension and all free features. Nothing is deleted.
Does it work with Google Workspace? ⌄
Yes. CodeCompose works with both personal Gmail accounts and Google Workspace (formerly G Suite) accounts. As long as you're composing email in Gmail's web interface, the extension works the same way.
Does my recipient need CodeCompose to view the code block? ⌄
No. Code blocks are inserted as standard HTML with fully inline styles — no external stylesheets, no plugins required. Your recipient sees the syntax-highlighted code directly in their email client, whether they use Gmail, Outlook, Apple Mail, or anything else.
