AI Safety, Privacy & Secure Data Masking

Use AI for SQL and JSON without exposing real schemas or sensitive data. Our tools run 100% client-side—nothing leaves your browser. AI safety and privacy first: mask before you send, restore after you get AI help.

JSON Shield

Mask JSON payloads before sending to ChatGPT or any AI. Keys become K_00001, string values become S_00001; numbers stay unchanged. Preserve structure, restore exactly. Perfect for API payloads, logs, and configs—no data leaves your browser.

  • • Mask keys & string values; keep numbers
  • • Deterministic, fully reversible mapping
  • • Client-side only; enterprise-safe
  • • Handles large payloads (MBs)

SQL Mask

Mask table and column names in raw SQL before sending to AI. Tables → T_00001, columns → C_00001. Compiler-level, token-aware masking—no regex, no broken strings. Send masked SQL to AI, paste the response, restore to real names in one click.

  • • Hide database schema from AI
  • • Deterministic reversible mapping
  • • Client-side only; no server, no logging
  • • Handles procedures, CTEs, complex SQL

MySQL Mask

Use AI for MySQL without exposing your schema. Same engine as SQL Mask: define tables and columns (or paste MySQL), get masked prompts. Build AI-safe prompts with optional JOIN definitions. Restore AI output to run in your MySQL database—privacy and compliance preserved.

  • • Anonymize MySQL schema for AI
  • • Prompt compiler with JOIN support
  • • No server storage; no schema logging
  • • FinTech, healthcare, banking friendly

Why AI safety and privacy matter

Sending raw SQL or JSON to AI can leak business logic, table names, and sensitive identifiers. Many policies forbid sharing schema with third parties. Our masking tools let you get AI help while keeping data on your device: mask → send only placeholders → restore. 100% data security, client-side only.

AI-Safe JSON & SQL Tools — Security First, Client-Side Only

All tools run 100% in your browser. No data storage on our servers—no uploads, no logging. Your JSON, SQL, and schemas stay on your device. AI safety and security by design: mask before AI, format and validate locally.
