The Problem Every AI User Has (But Most Ignore)
You open ChatGPT to ask for help with a customer email. You paste the email in. You hit send.
What you might not notice: that email contained the customer's full name, phone number, order history, and the database ID from your CRM. That information is now on OpenAI's servers. It was transmitted in plain text. It may have been logged.
This isn't hypothetical. It happens thousands of times a day. It's not carelessness — it's the natural way people use these tools. Grab the relevant text, ask the AI. The "clean it first" step doesn't exist for most people.
CleanMyPrompt adds that step. It sits between your data and the AI, strips what shouldn't leave your machine, and returns a clean version ready to paste.
What CleanMyPrompt Actually Does
CleanMyPrompt has three core functions:
1. PII Redaction
Before you paste text into any AI tool, the engine scans it and replaces sensitive values with safe, labeled placeholders:
| What it finds | What it replaces it with |
|---|---|
john.smith@acme.com |
[EMAIL] |
+1 (555) 867-5309 |
[PHONE] |
4111 1111 1111 1111 |
[CREDIT-CARD] |
sk-proj-xxxxxxxxxxxxx |
[OPENAI-KEY] |
aws_secret_access_key = xxxxxxx |
[AWS-SECRET] |
192.168.1.105 |
[IP-ADDRESS] |
AC1234567890abcdef... |
[TWILIO-SID] |
The AI still gets the structure and context it needs. It just doesn't get the live values.
2. Token Compression
AI models charge per token. Tokens are consumed by comments, blank lines, redundant phrases, and boilerplate the model ignores anyway. CleanMyPrompt's squeeze engine strips the noise:
- Repeated filler phrases ("in order to", "it is important to note that")
- Markdown overhead (
###,---,**bold**) - Trailing whitespace and empty lines
- Stop words (optional)
Average result: 25–40% token reduction — which translates directly to lower API costs and a better-utilized context window.
3. Text Cleaning
AI models respond better to clean inputs. The standard clean pass:
- Normalizes Unicode (removes smart quotes, em-dashes, zero-width characters)
- Fixes broken line breaks from PDF extraction
- Removes HTML artifacts and invisible formatting
- Standardizes whitespace
Who Uses CleanMyPrompt?
Developers — Paste code snippets into GitHub Copilot, ChatGPT, or Claude without accidentally sending API keys, database credentials, or .env values. See the VS Code extension and CLI.
Support Teams — Process customer tickets through AI for draft responses, without sending customer PII to a third-party model.
Legal & HR — Ask AI to review documents without exposing names, SSNs, or contract terms.
Healthcare — Add a redaction layer before clinical notes or medical records reach any model.
Developers Building AI Products — Use the REST API to add redaction + compression to any pipeline programmatically.
Four Ways to Use It
| Product | Best for |
|---|---|
| Web app | One-off cleaning, no install needed |
| VS Code extension | Developers using Copilot or Cursor daily |
| Chrome/Firefox extension | Auto-redacts on ChatGPT, Claude, Gemini as you type |
| CLI / npm | CI pipelines, git hooks, batch processing |
All four products share the same detection engine — findings are consistent across all of them.
Privacy by Design
CleanMyPrompt does not send your text to any server for processing. The web app, VS Code extension, and browser extension all process locally — in your browser or your editor. No telemetry. No analytics.
A redaction tool that strips PII by sending your data to its server defeats the purpose. The cleaning happens on your machine, before anything goes anywhere.
Try It in 10 Seconds
Go to cleanmyprompt.io. Paste any text — a customer email, a code snippet, a server log. Toggle Redact PII and Token Squeeze. See exactly what changed in the diff view.
No sign-up. No server upload. Nothing stored.
If it stops even one API key from being transmitted to a model you don't control, it's already paid for itself.
