Detection alone cannot keep pace with generative AI. Our 16,024+ domain blocklist provides the network-level enforcement layer that policies alone cannot deliver.
AI adoption among students has outpaced every institutional safeguard. AI-assisted cheating is no longer fringe behavior — it is the new normal.
Between 60% and 89% of college students have used generative AI for coursework. Among high schoolers, the figure exceeds 50% and keeps climbing.
Students view AI as efficiency, not cheating — making policy clarity essential.
Humanizer tools rewrite AI text so it scores as "likely human" on every major detector. Students paste ChatGPT output in and get undetectable text out.
Blocking humanizers is as important as blocking the generators themselves.
AI detectors produce false positive rates between 10% and 26%. Non-native English speakers are flagged at 2-3x the rate of native speakers.
Detection is a clue, not proof — never the sole enforcement mechanism.
Institutions that rely solely on detection are fighting a losing battle. AI generators improve every month, and humanizer tools evolve to defeat every new detector.
The strategy must shift from reactive detection to proactive prevention — blocking AI tools at the network level during assessments.
Updated policies and pedagogy address AI use during unsupervised work. This multi-layered approach is what actually works.
AI detectors are one tool in the integrity toolbox — but they should never be the only tool. Understanding their limitations is essential.
How detectors fail:
The real-world damage:
What humanizers do:
Why blocking humanizers matters most:
A student who cannot humanize AI output knows that raw AI text will be flagged — that alone is a deterrent. The 16,024+ domain feed includes hundreds of humanizer services most content filters have never categorized.
Below are examples of AI humanizer domains in our "Text & Language" category. Your content filter almost certainly does not categorize them — our feed does.

The paradigm shift
Instead of proving a student used AI after the fact, prevent access to AI tools during activities where their use violates policy. No accusations, no detective work, no false-positive fallout.
When AI domains are blocked at DNS or firewall level, students on the school network simply cannot reach them. The block is invisible, automatic, and requires no student cooperation.
During proctored exams, the testing environment is clean by design. During class time, students on in-class assignments cannot outsource thinking to a chatbot.
Deploy 16,024+ classified domains that update daily — covering obscure alternatives, new launches every week, and humanizer services students use to launder AI output.
Pair the blocklist with your existing content filter or DNS resolver to close the gap between policy intent and technical enforcement.
See the K-12 content filtering guide or the firewall admin integration guide for step-by-step setup.
| Factor | Detection | Prevention |
| Timing | After submission | Before access |
| False positives | 10–26% | 0% |
| Faculty burden | High (review each flag) | None |
| Humanizer bypass | Easily defeated | Humanizers also blocked |
| Legal risk | Wrongful accusation | Minimal |
The strongest integrity programs combine three layers:
High-stakes assessments require the strictest controls. Combine lockdown browsers, secure networks, and domain-level blocking to make AI tools technically unreachable.

Restricts the student to the exam application. Prevents tab switching and app access. Effective on managed devices but limited on BYOD.
Blocks all 16,024+ AI tool domains at the network level. Works on any device connected to the exam network.
Log every blocked DNS query during exam periods. Captures timestamp and device for any AI tool access attempts.
When prevention is the primary control, detection becomes a safety net. Use AI detectors to flag submissions for review — never as the sole basis for an accusation.
Automated Scan
Turnitin, GPTZero, or Originality.ai produces a probability score for each submission.
Threshold Flagging
Submissions above a configurable threshold are flagged for faculty review. No automatic violation marking.
Faculty Review
The instructor reviews the flagged submission in context, considering the student's writing history and the assignment type.
Student Conversation
A conversation with the student occurs before any formal charge is filed. Judgment stays with the instructor, not the algorithm.

Most institutional honor codes predate generative AI. Updating them with explicit AI provisions is essential for clarity and legal defensibility.
Defines unauthorized AI use — what counts as a violation and what does not
Distinguishes permitted from prohibited uses — three levels of AI allowance per assignment
Establishes a clear adjudication process — how alleged violations are investigated and resolved
Specifies consequences — and acknowledges that network-level blocking and detection tools supplement but do not replace the code
The school district AI policy guide covers the broader policy development process, including stakeholder engagement and board approval.
# ============================================================ # AI Academic Integrity Policy — Honor Code Addendum Template # Adapt for your institution's existing honor code structure # ============================================================ SECTION 1: DEFINITIONS 1.1 "Generative AI Tool" means any software, service, or application that uses artificial intelligence to generate, complete, paraphrase, rewrite, or substantially transform text, code, images, audio, or other academic work product. This includes but is not limited to: ChatGPT, Claude, Gemini, Copilot, Perplexity, QuillBot, and similar services. 1.2 "AI Humanizer Tool" means any service that modifies AI-generated content with the intent to evade AI detection software. Use of humanizer tools constitutes a violation regardless of whether the underlying content was AI-generated. 1.3 "Unauthorized AI Use" means use of a generative AI tool in connection with academic work where such use has not been explicitly permitted by the instructor for that assignment. SECTION 2: CLASSIFICATION OF ASSIGNMENTS Instructors shall classify each assignment using one of three AI-use levels, communicated in the assignment instructions: [LEVEL 0] NO AI PERMITTED All work must be the student's own. Any use of generative AI tools constitutes a violation. Applies by default to all in-class exams, quizzes, and proctored assessments. [LEVEL 1] AI PERMITTED WITH DISCLOSURE Students may use AI tools for brainstorming, outlining, or drafting, but must: (a) disclose which tools were used, (b) describe how they were used, and (c) submit all AI- generated content alongside the final submission. [LEVEL 2] AI USE ENCOURAGED The assignment is designed for AI-assisted work. Students are expected to use AI tools and reflect on the process. SECTION 3: ENFORCEMENT 3.1 The institution employs network-level technology to block access to generative AI tools on exam networks and during proctored assessments (Level 0 assignments). 3.2 AI detection software may be used as a supplementary screening tool. Detection scores alone are not sufficient evidence for a violation finding. 3.3 Violations follow the existing academic misconduct adjudication process, including the right to a hearing.
The barrier to cheating has dropped to zero
Instead of paying $200 for a custom essay, students generate comparable output for free in seconds. A student who would never have paid an essay mill will happily use a free chatbot.
Volume explosion
AI-assisted submissions are orders of magnitude higher than contract cheating ever was.
Growing sophistication
Students prompt AI with rubrics, citation styles, and request deliberate imperfections to mimic their voice.
Double evasion
AI humanizers add a second evasion layer that essay mills never needed.

How it works: When a blocked domain is accessed, the DNS filter logs the attempt with timestamp, device identifier, and domain requested. Logs export to your SIEM, LMS analytics dashboard, or custom reporting tool.
This script parses DNS filter logs to generate per-exam integrity reports for faculty review.
#!/usr/bin/env python3 # ai_integrity_report.py — Generate per-exam AI access reports # Parses DNS filter logs for blocked AI tool queries import csv import json from datetime import datetime, timedelta from collections import defaultdict def generate_exam_report(log_file, exam_start, exam_end, output): """Parse DNS logs for AI tool access attempts during exam window""" attempts = defaultdict(list) with open(log_file) as f: for line in f: record = json.loads(line) ts = datetime.fromisoformat(record["timestamp"]) if exam_start <= ts <= exam_end: if record["action"] == "BLOCKED": attempts[record["device_id"]].append({ "time": ts.isoformat(), "domain": record["query"], "category": record.get("category", "Unknown") }) # Generate faculty report with open(output, "w") as f: writer = csv.writer(f) writer.writerow(["Device", "Total Attempts", "Domains Attempted", "First Attempt"]) for device, logs in sorted( attempts.items(), key=lambda x: len(x[1]), reverse=True ): domains = set(l["domain"] for l in logs) writer.writerow([ device, len(logs), "; ".join(domains), logs[0]["time"] ]) return len(attempts) # Usage: # python3 ai_integrity_report.py flagged = generate_exam_report( log_file="/var/log/dns-filter/queries.jsonl", exam_start=datetime(2025, 5, 15, 9, 0), exam_end=datetime(2025, 5, 15, 11, 0), output="exam_ai_report_2025-05-15.csv" ) print(f"Flagged {flagged} devices with AI access attempts")
No single tool or policy can solve this. The institutions that succeed treat it as a systems problem — technology, policy, and pedagogy reinforcing each other.
Most relevant to academic integrity
Of 18 categories in our AI tool taxonomy, "Text & Language" covers AI chatbots, essay writers, paraphrasers, summarizers, humanizers, and grammar tools with generative capabilities.
Flexible blocking strategies
Block all 18 categories during exams. During instruction, block only "Text & Language" and "Code & Development" — or block everything and whitelist specific tools teachers request.
ChatGPT, Claude, Gemini, Copilot, Perplexity, and thousands of alternatives that generate essays, solve problems, and write code.
Undetectable.ai, StealthWriter, BypassGPT, and similar tools that rewrite AI output to evade detection software.
Specialized tools that generate complete essays, research papers, and homework answers — often marketed directly to students.
Technology enforcement is the foundation. When AI tools are unreachable on your network, policies have teeth, detectors become a safety net rather than the front line, and faculty can focus on teaching instead of policing.
