- The primary user is not an employee with one attachment. It is an MSP or security consultant rolling out Microsoft 365 Copilot across 5–50 clients, or an IT/security owner for contracts, financial reports, and policy documents.

Competitive Landscape

  • [Veridicus Scan](https://veridicuscan.app/) already supports local PDF, DOCX, and HTML inspection, evidence reports, and MCP workflows.
  • [AI Cordon](https://ai-cordon.com/en/) offers indirect-injection checks for documents and RAG chunks, starting with 1,000 free checks and then roughly €1/10 checks.
  • [StackOne Defender](https://www.stackone.com/platform/prompt-injection-guard/) provides an Apache-2.0 local CPU detector with published size and latency claims. Baseline semantic detection is not a moat.
  • [Elysia’s PDF Prompt Injection Scanner](https://elysiatools.com/en/tools/pdf-prompt-injection-scanner) detects hidden, off-page, tiny, and layered PDF text for free.
  • Microsoft Defender inspects email before delivery; Microsoft 365 Copilot also has runtime protections and security dashboards for DLP, oversharing, and governance. This product cannot replace platform controls.
  • The wedge is DOCX-specific before/after forensics: structure channels, numerical/contract changes, hidden-fragment replication, source relationships, and human approval in one evidence timeline. Most competitors produce a single-file verdict or API block.
  • **SERP occupancy**: direct products own the task term; Microsoft owns the broad branded term. Entry requires long tails such as “AI-edited DOCX comparison,” “Copilot document forensics,” and “hidden text in Word AI,” plus MSP distribution. Recheck the US English Top 10 before launch.

Why Build This

  • The primary user is not an employee with one attachment. It is an MSP or security consultant rolling out Microsoft 365 Copilot across 5–50 clients, or an IT/security owner for contracts, financial reports, and policy documents.
  • They may understand prompt injection conceptually but lack a lightweight, private way to prove what changed between the incoming file and the AI-edited output.

What to Build

Target User

MSPs deploying Microsoft 365 Copilot across 5–50 clients, security consultants, and enterprise IT/security owners of contract, financial-report, and policy workflows.

Core Function

not “is this file safe?” but “what can a person see, what might the model read, what changed after AI editing, was a hidden fragment copied, and where is the evidence?”

Differentiation

1.

07

How to Monetize

Primary

$99 Copilot Document Risk Pilot: 20 pairs, onboarding, and a white-label sample report.

Secondary

$29/month solo consultant plan after repeat use.

🔒 The lines above are the model’s basic take — the full playbook is for members

The monetization playbook maps 4 paths — who pays, at what moment, how much — each checked against free alternatives, differentiation, and path friction, with measured CPCs as evidence of willingness to pay.

MVP Checklist

  1. 1.Define finding schema, coverage matrix, synthetic DOCX fixtures, and the “does not prove safety” boundary.
  2. 2.Implement local single-file decompression, core XML parsing, and Visible/Model-visible views.
  3. 3.Add hidden/style/comment/revision/relationship/encoding rules and evidence drawer.
  4. 4.Add two-file text, number, critical-term, hidden-fragment, and relationship diffing.
  5. 5.Add disposition, hashes, and HTML/JSON/Markdown export.
  6. 6.Build Sample Report, Methodology, Privacy, About, and FAQ.
  7. 7.Add the `$99 pilot` Payment Link, lead form, and anonymous funnel events.
  8. 8.Complete fixtures, Playwright core flow, build, and SEO checks.
  9. 9.Validate parsing with 5–10 authorized real DOCX files before launch.

Risks

  • △Detection cannot prove safety; evasions, false positives, and false negatives can create dangerous confidence.
  • △Microsoft, Veridicus, and open-source detectors already cover substantial scope. Separate budget for before/after forensics is unproven.
  • △Microsoft could add native Word provenance, hidden-content warnings, or broader Defender/Purview coverage quickly.
  • △DOCX style inheritance, theme colors, fields, embedded objects, and corrupt files create parser boundaries that must be documented.
  • △Contracts and financial documents are highly sensitive. Uploads, logs, or third-party analytics would break trust.
  • △A branded report could be mistaken for certification. It must say “forensic aid,” not “security assessment passed.”
  • △Direct products occupy the head term and Microsoft occupies the brand term. Acquisition depends on MSP channels and demonstrable cases.
  • △Incident attention may decay quickly. Without an ongoing governance/forensics workflow, retention will remain low.
