02 / How it works
Levels of evidence
Higher levels of app integration increase our technology's confidence that a human wrote the text.
Keystroke timing was captured by the Chrome extension as the author typed, then analyzed against human capability thresholds to verify a natural writing rhythm.
- Chrome extension keystroke capture
- In-platform composition verified
- Human-like typing analysis
Why this score
- The number
- 75 out of 100. Each level has its own band: this text is at the chrome extension level, which runs 63 to 79.
- Where the typing came from
- Captured in the browser, keystroke by keystroke, as the text was typed.
- What held it here
- Typing was recorded in the browser. Browser-only evidence tops out at 79; higher scores need the desktop app's hardware keystroke check.
- What would raise it
- Running the desktop app while typing adds a hardware keystroke check and can lift a text to the desktop app level (80 to 89).
Confidence
How confident is this verification?
Typing evidence powers the confidence score.
75/ 100
Notes
- Very short text. There is not enough data for reliable typing rhythm analysis. Longer text produces stronger confidence.
- Typing rhythm is consistent with human input.
The “Typing evidence” view on the letter above marks each part of the text by how it was written, and the play button replays the typing as it happened. Here is the same thing as totals.
- Typed 100% Typed key by key with a human rhythm.
The typing engine scores the timing of every recorded keystroke. It looks at the signals below together; no single one decides the verdict. The exact measurements stay private so the check is hard to game.
- Typing speed
- How fast the text was typed, overall and in short bursts. People speed up and slow down; a script tends not to.
- Gaps between keys
- The pauses from one key to the next. Fingers have a floor; replayed or injected text often does not.
- Rhythm
- How uneven and unpredictable the rhythm is. Real typing is bumpy; machine typing is suspiciously even.
- Key presses
- How long keys stay pressed and how the fingers travel between them, when the recorder sees both key down and key up.
- Thinking pauses
- The longer pauses people take to think between phrases.
- Edits and fixes
- Deleting and rewriting. People revise as they write; pasted or generated text usually arrives finished.
Taken together, these signals read as a person typing at a keyboard.
The server signed a hash of this exact text together with its tier and author. Anyone can check the signature against the public key below. If a single character of the text changed, the content hash would not match.
