1. Close to 0% "Revision Effort"

Process Feedback tracks the ratio of Initial Drafting vs. Revision Time.

• Real Humans: A real student alters their thesis, deletes awkward sentences, shifts a sentence from the top of a paragraph to the bottom, and swaps out vocabulary as they write.

• The Simulator: Extensions like Natural Typist take a finished block of AI-generated text and type it out from start to finish. Even if the extension is set to introduce artificial typos and fix them, the report will show almost zero structural revisions (no moving blocks of text, no rewriting entire paragraphs, and no rethinking arguments).

2. Perfectly Proportional Paragraph Times

Process Feedback shows the time spent on each paragraph.

• Real Humans: A student might spend 25 minutes struggling to write a 4-sentence introductory hook, but then breeze through a 10-sentence evidence paragraph in 10 minutes.

• The Simulator: Because a bot types at a set average pace (e.g., 60 WPM), the time spent on every paragraph will be mathematically proportional to its length. A paragraph that is twice as long will take exactly twice as long to type.

3. Chronological/Linear Writing

If you look at the timeline or replay the writing process, a simulator writes strictly from the first word of the title to the very last word of the conclusion. It is incredibly rare for a student to write a high-quality academic paper completely linearly without ever jumping back to add a transition, fix an earlier argument, or adjust their thesis based on what they wrote in the body paragraphs.

4. Robotic Break Patterns and "Fluency"

Extensions allow users to customize breaks, but they usually deploy them mathematically (e.g., pause for 45 seconds every 10 minutes). Real human writing breaks are erratic—sometimes a student stops for 3 minutes mid-sentence to think or check a source, or they type in quick bursts of fluency followed by periods of stalling. A simulator will produce an unnaturally flat or perfectly rhythmic "Fluency" graph.

5. Includes all the Text (Ai Promt and suggestions)

Sometimes students are careless when copying text into a typing simulator. They may accidentally paste the AI prompt or greeting (e.g., "Certainly! Here is a 500-word essay on...") into the extension UI. The extension will then faithfully type out the AI's greeting into the Google Doc and delete it a few seconds later. When you look at the granular history of what text was inserted and deleted, these telltale AI phrases often appear.
