AI Content Detection
This guide explains the DrillBit AI Content Detection PDF Report — the downloadable PDF document DrillBit generates when a document is checked for AI-generated text. The report estimates how much of the submitted document was written by an AI tool and visually highlights the sentences DrillBit considers likely AI-generated. Every AI report uses the same structure regardless of the result, and the rest of this guide walks through every parameter you will see on the report.
How to Read an AI Content Detection Report
The DrillBit AI Content Detection report is a multi-page PDF. The first page is a one-glance summary of the document and the result; the remaining pages render the original document text with AI-detected sentences highlighted in yellow. Before diving into individual parameters, here is what the report looks like end to end as you scroll through it:
The report has two logical sections, in this order: a Cover Summary with submission metadata, the AI Text percentage, the Content Matched pie chart, and a disclaimer; followed by the Highlighted Document Content showing the original document with every AI-detected sentence flagged inline in yellow. The rest of this guide walks through every parameter in each section.
Cover Summary
The cover is a single-glance summary of the document and the AI Text result. It is split into three blocks — Submission Information, Result Information, and a Disclaimer — with a Content Matched pie chart sitting alongside the result.
Submission Information
This block records the identity of the document and the person who submitted it. Every field is captured at the moment of upload and cannot be edited afterwards. Watch the animation below as each field is explained:
- Author Name: The name entered for the document's author at the time of submission.
- Title: The document title as supplied during upload. This appears on every downloaded copy of the report.
- Paper / Submission ID: A unique numeric identifier DrillBit assigns to the submission. Use this ID when raising a support ticket so the support team can locate the exact report.
- Submitted By: The email address of the account that uploaded the document.
- Submission Date: The timestamp the document was received, recorded in
YYYY-MM-DD HH:MM:SSformat. - Total Pages: A count of how many pages of content were scanned by the AI detector. Unlike the similarity report, the AI report does not separately list the word count.
- Document type: The kind of source DrillBit detected — for example Assignment, Article, Thesis, or Synopsis.
Result Information
This is where the headline number lives. The AI Text percentage is DrillBit's estimate of how much of the document was written, or assisted, by an AI tool. It is rendered in red so the figure is easy to spot at a glance. Watch the percentage count up to the final value, then the Content Matched pie chart drawing in to show how the document splits between AI-generated and human-written text:
Two things to know about the headline figure:
- AI Text: The single most important figure on the report. It expresses, as a percentage, how much of the document DrillBit estimates was produced by an AI tool. The figure is always rendered in red regardless of how high or low it is — the red colour is purely a visual cue that this is the result number, not a signal of severity.
- Content Matched chart: A two-segment pie chart that visualises the same number alongside its complement. The blue segment is AI Text; the lighter segment is Human Text. The two segments always add up to 100% of the analysed content. The chart is functionally redundant with the percentage but makes the result instantly readable in a printed report or presentation.
Disclaimer
Every AI Content Detection report carries a three-line disclaimer at the bottom of the cover page. The disclaimer is not a generic legal note — it is a deliberate reminder that AI detection is fundamentally probabilistic, and the report should never be the only basis for a decision:
- Powered by AI technology: The detection itself uses AI models trained to recognise patterns common in AI-generated text. Like any AI model, those patterns can be imperfect.
- Not always accurate: The result is a probability estimate. Genuinely human-written text can occasionally be flagged, and AI-generated text can occasionally pass undetected — especially as AI tools evolve.
- Designed to assist: The report is meant to help an instructor, supervisor, or author identify candidate sections that may warrant a closer look. It is a moderation aid, not a final verdict.
Highlighted Document Content
After the cover, the rest of the report is a faithful render of the original document text with every AI-detected sentence visibly highlighted in yellow. Each highlighted span represents a sentence (or phrase) that DrillBit's model considered likely to have been generated by an AI tool. Sentences that the model considered human-written are left unhighlighted:
How to use the highlighted content section:
- Read the highlighted sentences in context. An AI-generated sentence often has a noticeably different rhythm, vocabulary, or formality compared to the surrounding text. Reading the document straight through usually makes any contrast easier to spot.
- Look at the proportion, not just the count. A handful of flagged sentences in a long document is very different from half the document being highlighted. The cover page percentage and the visual density of yellow on these pages should agree — if they do not, treat the result with extra caution.
- Use the highlights as conversation starters, particularly with student work. Ask the author to talk about a flagged passage in their own words; this often clarifies whether the section was written by them, paraphrased from another source, or generated.
