Engineered for Speed.
Built for Absolute Privacy.
LineCounter AI was created to provide developers, writers, editors, and students with an instantaneous, private, and developer-grade utility for counting lines of text, source code SLOC, character limits, and screenshot text.
Why We Built LineCounter AI
Counting lines of code, checking character density, or formatting digital text has traditionally forced engineers and content creators to make an uncomfortable trade-off: either install heavy desktop command-line utilities or paste proprietary source code into ad-heavy online websites that upload private payloads to remote cloud servers.
We believed there was a better way. Modern web browsers are powerful execution environments capable of processing millions of characters in milliseconds. LineCounter AI was architected to eliminate server round-trips entirely, delivering sub-millisecond computations directly in your browser's private memory sandbox.
Core Technology & Architectural Pillars
Language-Aware SLOC Parser
Differentiates executable statements from single-line comments (//, #, --), multi-line blocks (/* ... */, """ ... """), and blank lines across JavaScript, TypeScript, Python, Rust, Go, C++, Java, and more.
In-Browser OCR Extraction
Powered by client-side WebAssembly optical character recognition. Paste any clipboard screenshot or drag an image to extract text lines instantly without cloud APIs.
Instant Line Transformations
Batch line numbering, duplicate removal, natural sorting (A-Z, length), whitespace trimming, and custom prefix/suffix insertion execute in sub-millisecond runtime.
Zero Data Retention
Your data exists only in volatile browser memory while the tab is open. When you clear the editor or close the page, the data is completely erased.
Who Uses LineCounter AI?
