Highlight 1
Real-time character-level diffing provides instant feedback and makes it very efficient for users comparing code or text.
Highlight 2
The shareable link feature with compressed content is practical, enabling easy collaboration without requiring file uploads.
Highlight 3
The minimalist UI ensures clarity and reduces distractions, making the tool approachable even for non-technical users.

Limited support for file formats (currently text-only) — expanding to document or code file uploads would increase usability.
Improvement 2
Lack of collaboration tools such as commenting or version history makes it less useful for teams working together.
Improvement 3
SEO and discoverability could be improved; the site is functional but lacks onboarding, tutorials, or clear differentiation from established diff tools.
