What AI sees about you — before you clean it.

Freshmii scans prompts for personal data, redacts files and screenshots, and strips hidden metadata — all in your browser. Nothing reaches our servers, even if you go offline.

What is Freshmii?

Freshmii is a free set of privacy tools that clean your text and files before you send them to an AI assistant like ChatGPT, Claude, or Gemini. It finds and removes personal details — names, phone numbers, emails, ID numbers, and the hidden data tucked inside photos and documents — right inside your browser. Nothing is uploaded to our servers, and you never need an account.

How it works

1

Paste or drop your content

Paste a prompt, upload a photo, or drop a PDF you are about to send to an AI assistant.

2

Scan or redact in your browser

Common sensitive data is found and replaced automatically; you review the results, restore false positives, or manually label anything missed. Everything runs on your device, not a server.

3

Copy or download the clean version

Paste the cleaned prompt into ChatGPT, Claude, or Gemini. Download the redacted file. The sensitive details stayed with you.

Privacy tools by content type

All privacy tools

Metadata Inspector — Check EXIF, GPS, PDF, and DOCX Fields

Before you upload a photo or document to ChatGPT, Claude, or Gemini, it helps to know what's hidden inside it — a phone photo alone usually carries the GPS coordinates of where it was taken, the exact capture time, and your device model. Drop a photo, PDF, or DOCX here and see everything it exposes, grouped by privacy risk — GPS location, author name, timestamps, document properties, comments, and more. Nothing is uploaded; the inspection runs entirely in your browser.

Metadata Remover — Strip EXIF, GPS, and Author Data

A photo or document carries more than you can see — a smartphone photo alone usually embeds the GPS coordinates of where it was taken, the time, and your device model. Upload it to ChatGPT, Claude, or Gemini and all of that goes with it. Clean it first. Drop the file here, choose which categories to strip, and download a clean copy. GPS, author names, timestamps, camera data, document properties — all removed on your device, and your files never leave your browser.

Screenshot Redactor - Black Out Sensitive Details Locally

Screenshots are one of the easiest ways to leak something to an AI — a terminal grab with an API key, a support chat with a customer's name and email, a banking app showing your balance. Before you paste one into ChatGPT or Claude, black out the sensitive parts. Drop or paste the screenshot, draw boxes over anything private, and download a cleaned image. The redaction happens in your browser, so your screenshot never reaches our servers.

PDF Redactor - Redact Sensitive PDF Content Locally

Uploading a PDF to ChatGPT, Claude, or Gemini sends everything inside it — names, account numbers, signatures, case details — to a third party that may store it or use it to train its models. Clean it first. Drop the PDF here, draw boxes over anything sensitive, and download a redacted copy. The redaction runs entirely in your browser, so the file never reaches our servers — and only the cleaned version ever reaches the AI.

AI Prompt Privacy Checker — Remove Sensitive Data Before AI

When you paste text into ChatGPT, Claude, or Gemini, every word may be stored, reviewed, or used to improve the AI — including names, phone numbers, passwords, or other private details you didn't mean to share. This tool scans your text and automatically replaces common sensitive data with labels before you paste it into an AI chat. Click Scan, review what was replaced, restore anything the scanner got wrong, manually label anything missed, then copy the cleaned version. Everything happens inside your browser — nothing you type is ever sent to our servers, and no account is needed.

AI Text Cleaner — Remove Markdown and Hidden Characters

Got AI output you want to paste into an email, a document, or a CMS? Paste it here, choose what to strip — markdown headings, bold markers, hidden Unicode, filler phrases, emojis, or HTML tags — and get clean plain text back. Everything happens in your browser. Nothing is uploaded anywhere.

AI privacy basics

AI Privacy Checklist Before Using ChatGPT, Claude, or Gemini

A before-AI privacy workflow for reducing exposure before content reaches an AI provider. Decide what the model actually needs, use automatic detection plus review controls to replace sensitive strings with placeholders, check visible and hidden file data, verify the cleaned copy, and then review the privacy controls for the account you are using.

Prompt privacy

What Not to Paste Into AI Prompts

A practical guide to prompt privacy. Learn which categories of text should be treated as no-paste by default, how automatic detection plus review controls can replace sensitive strings with useful placeholders, and when a sanitized prompt is safer than a full copy of the original note, log, email, or document excerpt.

File upload privacy

Check Files Before Uploading Them to AI

A file-upload privacy guide for AI workflows. Learn how to separate visible content from hidden metadata, how to triage images, screenshots, PDFs, and DOCX files, and which local Freshmii tools to use before a file reaches an AI provider.

PDF redaction

Redact PDFs Before Uploading Them to AI

A PDF privacy guide for AI uploads. Learn why visible redaction and metadata cleanup are separate jobs, how to verify a redacted PDF, and when to use local PDF redaction before sharing statements, contracts, forms, reports, or case documents.

Verify it yourself — no trust required

Open DevTools → Network tab. Paste your most sensitive text. Watch the requests. Zero uploads to Freshmii — or anyone else.

Go further: disconnect your WiFi, then scan. Our WASM engine runs in your browser's memory. It doesn't need a server, so it works offline by design.

Frequently asked questions

Does Freshmii send my data to a server?

No. Every tool runs entirely in your browser using a compiled WebAssembly (WASM) engine. Nothing is uploaded to Freshmii or any third party. Verify it yourself: open DevTools → Network tab → paste your text → zero requests fire to our servers.

What personal information does Freshmii detect?

Freshmii detects 30+ types of sensitive data, including full names, email addresses, phone numbers, Social Security Numbers, credit card numbers, API keys, IP addresses, dates of birth, passport numbers, and bank account numbers. All of this detection happens on your device, so none of it is uploaded while it is being found and replaced.

How does Freshmii work offline without an internet connection?

Freshmii's detection engine is compiled to WebAssembly and runs entirely in your browser's memory. Once the page loads, every tool works without a network connection. Disconnect your WiFi and paste text into the Prompt Checker — it still detects and redacts. No server is involved at any point.

Can I use Freshmii before pasting into Claude, Gemini, or other AI tools?

Yes. Freshmii works with any AI tool — use it before pasting into ChatGPT, Claude, Gemini, Copilot, Llama, or any AI assistant. Clean or redact in Freshmii, then paste the cleaned version. The AI assistant only ever sees the cleaned copy.

Is Freshmii free?

Yes. All six tools are completely free to use, with no limits, no trial, and no account required. Just open a tool and start. There is nothing to buy and no premium tier.

Do I need to install anything or create an account?

No. Freshmii runs entirely on the website in your browser. There is no extension to install, no app to download, and no sign-up. Open the page, use the tool, and close the tab when you are done.

Is it safe to upload files or personal information to AI tools?

Treat every upload as sharing data with a third party. Each AI provider has its own rules for how it stores and uses what you send, and those rules change. The one step you fully control is removing private details before they ever reach the AI. Clean your text and files in Freshmii first, then share the cleaned copy.
