Privacy-first tools
Browser-local tools to inspect metadata, redact visible details, automatically detect sensitive prompt data, and clean AI output before private content reaches an AI assistant or another sharing destination.
Free browser-local image privacy tools. Inspect EXIF, GPS, and hidden metadata; remove sensitive fields by category; and black out visible screenshot details. Everything runs in your browser — your files are never uploaded to our servers.

Explore →Every tool runs in your browser using JavaScript and WebAssembly. Your files and text are processed on your own device, never sent to a conversion or AI API.
This is an architecture choice, not just a policy sentence. You can verify it by watching your browser's Network tab while running a tool — nothing leaves.
Metadata tools show and remove hidden GPS, author, timestamp, camera, PDF, and DOCX fields before a file leaves your device.
Redaction tools cover visible sensitive details in screenshots and PDFs before you attach or upload them.
Text tools help with both sides of AI work: automatically detect common sensitive data before sending a prompt, then review, restore, or manually label anything missed; after the AI responds, clean generated formatting before reusing output.
Each tool targets one practical question: what does this content reveal, and what should be cleaned before the next app sees it?
Choose an image privacy task based on what needs to be checked or cleaned before you share.
Free browser-local metadata inspector for checking what a file exposes before you upload or share it. Drop a photo, PDF, or DOCX and get a full privacy report — GPS coordinates, EXIF fields, author names, timestamps, document properties, and more, grouped by risk level. Export a JSON or CSV report if you need a record. Your file never leaves your browser.
Free browser-local metadata remover for stripping hidden file data before sharing or uploading to AI. Remove GPS, EXIF, author, timestamp, camera, PDF document properties, and DOCX metadata. Download a clean copy generated entirely on your device — nothing is sent to our servers.
Free browser-local screenshot redactor for hiding sensitive details before AI upload, support tickets, bug reports, or public sharing. Draw blackout boxes over names, emails, account numbers, API keys, addresses, and internal URLs, then download a clean copy. Your screenshot never leaves your browser.
Redact sensitive content before sharing, forwarding, or uploading a PDF.
Free browser-local PDF redactor for covering sensitive document content before AI upload, email, or external review. Draw and adjust redaction boxes over sensitive areas and export a redacted PDF copy. Your PDF never leaves your browser. Pair with Metadata Remover when hidden document properties also need cleanup.
Use the prompt checker before sending text to AI, or the text cleaner after getting a response you want to reuse.
AI Prompt Privacy Checker scans text for personal information and removes it before you paste into ChatGPT, Claude, Gemini, or Copilot. Paste any text — a customer email, a work document, a debug log, or draft notes — and click Scan. The tool automatically finds and replaces sensitive details including email addresses, phone numbers, national ID numbers, credit card numbers, bank account numbers, API keys, passwords, IP addresses, street addresses, dates of birth, and more. Everything runs inside your browser — nothing is sent to a server. If the scanner replaces something it shouldn't have, you can restore individual items with one click. You can also add your own labels to manually label anything the scanner missed. Free, no sign-up required.
Free browser-local AI text cleaner for cleaning up AI output before reuse. Paste AI-generated text, choose the cleanup options you want, and remove markdown syntax, hidden Unicode, extra whitespace, filler phrases, emojis, and HTML tags. The cleaned text replaces the original in the same textarea. Your text never leaves your browser.
These guides explain the privacy decisions behind the tools: what to remove, what to inspect, and how to verify a cleaner copy before an AI assistant sees it.
