Check and clean private data before you share it
Use focused browser tools for AI prompts, developer logs, structured data, screenshots, image metadata, tracking links, and file checksums—then review the exact final result yourself.
Choose the tool by what you are sharing
The site now uses a smaller set of canonical tools instead of many near-duplicate pages. Each tool has its own workflow, limits, tests, and supporting guides.
Remove PII Before ChatGPT
Clean private details from prompts, client emails, notes, and support messages before using AI.
Log Sanitizer for ChatGPT
Remove common secrets and private infrastructure details from logs while preserving debugging context.
JSON PII Redactor
Preserve valid JSON structure while masking sensitive keys and recognizable private values.
CSV Anonymizer and PII Scanner
Create a cleaned copy of CSV data while keeping rows, columns, quoting, and useful structure.
Screenshot Redactor
Cover names, emails, IDs, URLs, balances, tabs, and other visible details before sharing a screenshot.
JWT Privacy Checker
Inspect readable JWT claims before sharing a token in logs, tickets, screenshots, or AI prompts.
URL Privacy Cleaner
Remove common marketing and personal query parameters while preserving the destination URL.
Remove EXIF Metadata
Create a new pixel-only image copy in your browser before uploading or sharing a photo.

Start with the type of exposure you need to reduce
AI prompts and private text
Remove unnecessary identities, account references, private links, credentials, and business context before using an AI assistant.
Logs and structured data
Keep useful debugging structure while masking access-bearing secrets, customer identifiers, paths, payloads, and token claims.
Photos, documents, and files
Inspect image metadata, create clean copies, redact visible pixels, verify downloads, and follow safer PDF and ZIP workflows.
Understand exactly what the tools do
Local processing is useful, but it is not a complete security or compliance guarantee. The site documents implementation boundaries instead of hiding them.
How it works
See how text parsing, canvas rendering, metadata inspection, URL cleaning, and hashing are implemented.
Testing methodology
Review representative test cases, network checks, known false-positive risks, and unsupported formats.
Version history
Track consolidation, restored legacy topics, redirect changes, tool additions, and privacy-claim updates.
