1. Layout and Styling
The entire layout is created using TailwindCSS and custom CSS for advanced styling. The interface has a clean, minimal, and professional look using gradients, shadows, and rounded corners. It has a:
Header Section: Shows the title and purpose of the tool.
Text Input Area: Allows users to paste and analyze their text.
URL Input Area: Lets users input a webpage URL to scan its content.
Results Area: Displays results of plagiarism and grammar checking.
Footer: Branding and copyright message.
The styling includes responsive media queries to ensure accessibility on small screen devices. Custom styles complement the Tailwind utility classes for precise visual control.
This section contains:
A
<textarea>element for users to paste their content.An event listener (
oninput) triggers aupdateWordCount()function to calculate the word count in real time.Buttons to trigger plagiarism or grammar checking.
3. URL Checker
Another core feature is URL-based checking. Users can enter a URL, and the tool simulates extracting content from that page to run a plagiarism check.
The backend integration for real URL processing can be built using Python (e.g., Flask + BeautifulSoup) or Node.js for server-side content scraping.
Currently, the tool uses dummy logic to simulate a scan.
4. Plagiarism Detection Logic
Upon clicking the “Check Plagiarism” button, a simulated logic runs:
Randomly flags some words as plagiarized.
Calculates plagiarism % and uniqueness %.
Updates a circular SVG meter to visually represent these values.
Displays results by wrapping plagiarized words in red and unique words in black.
Example JavaScript Logic:
const isPlagiarized = Math.random() > 0.7;This random check serves as a placeholder for real API integration. You can connect this with:
Grammarly or Copyscape API
Custom-trained NLP model
SVG Meters:
Two
<svg>meters visually show:Plagiarized percentage in red
Unique percentage in green
5. Grammar Checker Simulation
A separate button runs a grammar error checker using simulated rules. For example:
Misuse of “your” instead of “you’re”
Double spaces
The grammar mistakes are highlighted using wavy underlines in orange and include tooltips when hovered.
6. Result Copying Feature
Users can copy the results shown in the results area with one click. This is useful for:
Saving corrected content
Reporting errors
Submitting for editing
7. Meter Component Details
Each circular progress meter consists of:
A background circle (gray)
A foreground circle (colored – red/green)
Stroke-dasharray used for dynamic progress
Where 314 is the full circumference, and 75 is the dynamic stroke calculated using percentage logic.
