Offline Document Redaction Tool for AI Uploads

FilePreflight inspects and transforms supported files on your Windows PC, then publishes a separate copy only after it reopens and passes a second check.

Product direction

Prepare locally. Upload only after a separate approval.

The processing path does not upload file bytes, extracted content, OCR text, findings, hashes, or other file-derived information. Pro purchase and license activation are separate network functions and must never include file data.

17 launch extensionsPDF, DOCX, XLSX, PPTX, JPEG, PNG, text, Markdown, log, CSV, JSON, XML, YAML, and .env variants within published limits.
Original preservedThe source is read-only. A successful output uses a separate, collision-safe -SAFE filename.
Reopen and recheckOnly an output that reopens and passes the post-sanitization check can be presented as a safe copy.

The local-to-cloud boundary

Source file→Local inspection and transformation→-SAFE copy→Your upload decision

“Local” describes FilePreflight file processing, not the cloud AI session that may follow. Once you choose to upload the prepared copy, the destination service's current plan, settings, retention, administrator access, and terms apply.

One product path, four visible outcomes

Safe copy createdThe output reopened, passed the supported checks, and is ready for your final review.
Review requiredThe app found something that needs a person's decision.
BlockedNo normal output is published because a critical issue remains.
FailedProcessing did not complete; the original remains unchanged.
