AI Prompt Redactor
No API key, no AI call — this scans and masks sensitive data entirely in your browser, before you ever paste anything into ChatGPT, Claude, Gemini, or any other AI chat.
How to use this AI prompt redactor
- Paste the text you're about to send to any AI chat.
- Choose which categories of sensitive data to mask.
- Click "Redact," then copy the safe version to paste into ChatGPT, Claude, or any other AI.
Why does this exist separately from OmniDeck's AI tools?
OmniDeck's other AI tools use your own API key sent directly to your chosen provider — but this tool is different on purpose: it's meant to run before you paste anything into any AI chat at all, including ChatGPT's or Gemini's own web interface, not just OmniDeck's own tools. It needs no API key and calls no model, because masking known data patterns is a task regular expressions handle perfectly well on their own.
Does this send my text to an AI to redact it?
No — this tool uses pattern matching (regular expressions) to find and mask sensitive data entirely in your browser. It never calls any AI model and never sends your text anywhere.
Will it catch every sensitive detail?
No — it catches common, structurally recognizable patterns (emails, API keys, cards, IPs, IBANs). It won't catch a sensitive detail with no fixed format, like a person's name or a confidential project codename — review the output yourself before pasting it anywhere.
Why pattern matching is the right tool for this specific job
Structured sensitive data — an email address, a credit card number, an API key with a recognizable prefix — follows a predictable, consistent format, which is exactly the kind of problem regular expressions were designed to solve reliably and instantly, without needing any actual understanding of the surrounding text at all. This is deliberately different from asking an AI model to find and redact sensitive information, which would require sending that same sensitive text to a model in the first place — defeating the entire purpose before the redaction even happens. Running the detection as plain pattern matching, entirely in your browser, means the sensitive data in question never has to leave your device even temporarily, not even to the AI provider you're trying to protect it from.
Why AI chat providers themselves don't offer this
Every major AI chat provider explicitly states in their own terms and privacy policies that conversations may be logged, reviewed, or used for model improvement unless you specifically opt out (and some plans don't offer an opt-out at all). None of them have a strong incentive to build a tool that actively discourages you from pasting your real data into their own product — that's a genuine structural conflict of interest a third-party tool doesn't have. A pre-flight scrubbing step run somewhere entirely outside that provider's own infrastructure is precisely the kind of safeguard that has to come from outside the provider relationship, not from within it.
What this tool is good at, and what still needs a human eye
Pattern-based detection is genuinely reliable for data with a fixed, recognizable structure — an email always has an @ symbol and a domain, an IBAN always follows the same country-code-plus-digits layout described in more detail on this site's IBAN Validator tool. It's fundamentally unable to recognize sensitive information with no fixed format at all — a client's real name, an unreleased product codename, a specific dollar figure in a confidential negotiation, a detail that's only sensitive because of context a regex has no way to know about. This is exactly why reviewing the redacted output yourself before pasting it anywhere remains a genuinely necessary step, not an excessive extra precaution — this tool catches the specific, structurally obvious categories reliably, but it isn't a substitute for actually reading what you're about to share.
Why this matters more, not less, as AI chat becomes part of daily work
As pasting a chunk of a document, a codebase, or a client email into an AI chat becomes a completely normal part of everyday work, the sheer volume of sensitive data flowing into third-party AI systems grows right along with it — and most of that data is pasted quickly, without a conscious moment of "wait, does this contain anything I shouldn't be sharing?" A habit of routing text through a quick scrub step first costs a few seconds and catches the specific, common categories of accidental exposure (a stray email signature, an API key left in a code snippet, a phone number in a forwarded message) that are genuinely easy to miss when copying and pasting quickly under time pressure.
Limitations of this tool
This tool detects the specific, structurally recognizable categories listed above using pattern matching entirely in your browser — it doesn't understand context, so it can't recognize sensitive information without a fixed format (names, internal project details, anything sensitive only because of what it means rather than how it's formatted). It also can't guarantee zero false negatives even within the categories it does check, since real-world data formats vary (an unusual phone number format, a less common API key prefix) — treat it as a fast first pass that catches the common, structural cases, not a guaranteed-complete privacy scan.
