AI JSON Redactor

Why redact JSON before using AI?

Pasting raw API responses, logs, or config into a chatbot can leak credentials, personal data, and internal details into a third-party service. Many teams are barred from sending customer data to external models at all. Redacting first lets you still get help debugging a payload without exposing the sensitive parts.

What it masks

The redactor works two ways. It masks any value whose key looks sensitive, and it inspects string values for patterns that are sensitive regardless of key name.

• Keys like password, secret, token, api_key, authorization, ssn, cvv
• Email addresses (keeps the domain for context)
• JWTs and access tokens
• Credit card numbers (keeps the last four)
• Phone numbers and IPv4 addresses

Deterministic and private

Redaction is rule-based and runs entirely in your browser — no model, no network calls — so the same input always produces the same masked output and nothing leaves your machine. The JSON shape is preserved (keys stay, only values are masked), so the redacted document is still valid JSON you can reason about or hand to an LLM.

Combine with clean and format

For the smallest, safest payload, pair the redactor with the JSON Cleaner to drop nulls and empty fields, then minify before sending to reduce token usage. The redactor handles secrets; the cleaner handles noise. Review the output before sharing — automated rules catch common patterns but can't know every custom field.
