Exact input

Syntax changes the rhythm

Code introduces paired brackets, indentation, symbols and case-sensitive identifiers. Ordinary prose speed is only part of the signal.

Safe by design

Targets are text, never execution

All snippets are original local content, rendered as plain text and analyzed without running any source code.

Measure what developers actually type

Results add symbol and bracket accuracy to core WPM, raw pace, accuracy and consistency. Use JavaScript, TypeScript, Python, HTML, CSS or SQL tabs to switch the target style.

Local syntax cues without a heavy runtime

A lightweight tokenizer colors keywords, strings, numbers, comments, operators, and brackets in the read-only target. Tokenization happens only when the passage or language changes; the per-keystroke comparison path remains focused on text accuracy.

Practice language-specific movement

Python makes indentation and colons frequent. JavaScript and TypeScript add braces, arrows, generic types, and template strings. HTML uses angle brackets and attributes, CSS mixes selectors with declarations, and SQL demands punctuation plus multiword clauses. Compare personal bests only within the same language and duration.

Quick answers

Frequently asked questions

01Does KeyVelocity execute the code?

No. Snippets are rendered and compared as plain local text. Nothing is compiled or executed.

02Why is code WPM often lower?

Code adds uncommon symbols, indentation, case changes and paired brackets. A prose WPM score is not directly equivalent.

03Which languages are available?

The interface includes original JavaScript, TypeScript, Python, HTML, CSS and SQL snippets, with at least five targets for each language.
