Protocol Deviation VS DocInspector

DocInspector is a privacy-focused document processing tool built for accountants, lawyers, HR teams, and anyone who handles sensitive files before sharing, archiving, or submitting them for compliance.

Two ways to use it:

Browser tools (free, all OS) — sanitize metadata, repair & OCR PDFs, add watermarks, encrypt, flatten, and redact directly in your browser. Files are processed in an isolated server sandbox in Germany (EU) and deleted immediately after download. No account required.

Desktop app (Windows) — install once, process unlimited files locally with no upload, no download, no internet required. No file size or volume restrictions.

What it does: - Strip hidden metadata from PDF, DOCX, XLSX, JPG, PNG, TIFF - Repair and rebuild corrupted or broken PDF structures - OCR scanned PDFs — makes text selectable and searchable - Watermark, encrypt, flatten, redact - Advanced Bundle Report — process a folder of hundreds of files, generate full inventory with SHA-256 hashes. Essential for legal evidence management and compliance auditing. - Batch process entire folder trees recursively (desktop)

Who it's for: Law firms, accounting offices, HR departments, compliance teams, notaries, and court filing professionals.

Why it's different: Unlike cloud-based PDF tools, DocInspector never stores your files. The desktop version works 100% offline — no upload, no wait time, no data leaves your machine. GDPR compliant by architecture.

Why should a person choose your product over its competitors?

Most PDF tools store your files on their servers — DocInspector never does.

Metadata stripping across multiple formats — PDF, DOCX, XLSX, JPG, PNG (not just PDF like ilovepdf or Smallpdf)
Advanced Bundle Report — SHA-256 hashes, page counts, full folder inventory in one click. Used by law firms and accounting offices for compliance auditing
Offline desktop app — no upload, no wait time, no data leaves your machine
For professionals handling contracts, legal files, HR records — zero cloud exposure is the deciding factor

How would you describe the primary audience of your product?

DocInspector's answer:

Professionals who handle sensitive documents before sharing them outside their organization:

Accountants & auditors — clean client files before delivery
Lawyers & notaries — strip metadata from contracts and evidence files
HR departments — sanitize employee records before archiving
Compliance & court filing teams — GDPR-ready document hardening
IT departments — air-gap-ready tool for secure offline processing

Who are some of the biggest customers of your product?

DocInspector's answer:

Law firms — using the Bundle Report for evidence file management and chain-of-custody documentation
Accounting offices — processing client document packages before submission to auditors
HR departments — cleaning employee files before archiving or external sharing
Notary offices — handling GDPR-sensitive documents in EU countries

What's the story behind your product?

DocInspector's answer:

Built after observing how often professionals unknowingly share documents with sensitive hidden metadata — revision history, author names, GPS coordinates from embedded images, internal comments.

Existing tools either stored files on the cloud or were too technical for non-developers. DocInspector was created to bridge that gap: powerful enough for compliance work, simple enough to use in seconds — no account, no installation required for the browser tools.
