Clipboard Sanitizer for Code Editors

Problem Context

Developers working on iPhones with Safari copy code from web sources and paste it into GitHub or other code editors. The copy-paste process corrupts straight quotes (“) into curly quotes (“)—even with Smart Punctuation turned off—breaking Python, JSON, and other syntax-dependent files.

Pain Points

The corrupted code looks fine visually but fails with syntax errors when run. Users have tried disabling Smart Punctuation, using the GitHub mobile app, and switching to single quotes, but nothing prevents the corruption during the copy-paste step. This forces them to manually edit files or switch devices, wasting hours per week.

Impact

Broken builds delay open-source contributions, waste debugging time, and frustrate developers who rely on mobile-first workflows. For freelancers or small teams, this adds unnecessary overhead to their development process, slowing down delivery and increasing stress.

Urgency

The problem occurs every time they paste code, making it a daily frustration. Without a fix, they’re forced to either accept broken builds or abandon mobile development entirely—neither is sustainable for long-term productivity.

Target Audience

Mobile-first developers, open-source contributors, freelance coders, and small teams that rely on iPhones for development. This also affects non-developers who occasionally edit code files (e.g., data analysts, sysadmins) and encounter the same corruption issues.

Solution Approach

A lightweight browser extension that automatically detects and sanitizes clipboard content before pasting into code editors. It replaces curly quotes (“) with straight quotes (“) and other problematic characters, ensuring the pasted code remains syntactically valid. The extension works silently in the background, requiring no manual intervention.

Key Features

1. *Editor Detection:- Works specifically in GitHub, GitLab, and other code editors (via URL or DOM detection).
2. *Custom Rules:- Users can add their own character replacements (e.g., for language-specific syntax).
3. Cross-Platform: Functions in Safari, Chrome, and Firefox on iOS and desktop.

User Experience

Users install the extension once and forget about it. When they copy code from a web page and paste it into a code editor, the extension silently fixes the quotes in the background. They see clean, error-free code ready to run—no manual edits or workarounds needed. For teams, the extension can be deployed via group policy or shared links.

Differentiation

Unlike manual workarounds (e.g., disabling Smart Punctuation), this extension fixes the problem at the source: the clipboard. It’s faster than switching apps or devices and more reliable than native iOS settings. Competitors either don’t exist (for this exact problem) or require complex setup (e.g., desktop apps).

Scalability

Starts as a freemium extension (free for basic use, paid for advanced features like team deployment). Later, add API access for CI/CD pipelines, integrations with IDEs, and enterprise plans for large teams. Monetization via subscriptions or one-time purchases.

Expected Impact

Eliminates syntax errors from corrupted pastes, saving developers 5+ hours per week. Reduces frustration and speeds up open-source contributions. For teams, it standardizes code pasting across devices, improving consistency and reducing bugs.
