Tools
Everything you need, daily
From JSON formatting to AI-safe data masking. All tools run in your browser with zero server calls for your payloads.
AI Schema Masker
Mask SQL table and column names before sending to ChatGPT. Fully reversible with one click.
JSON Prompt Shield
Mask JSON keys and values before AI. Keys → K_00001, strings → S_00001. Numbers unchanged.
Code Prompt Shield
Mask API keys, variable names, and secrets in code before sending to Copilot or ChatGPT.
How it works
Use AI safely in 4 steps
The AI Schema Masker workflow — applicable to SQL, JSON, and code.
Paste your data
Paste your SQL query, JSON payload, or source code into the tool. Nothing leaves your browser at this stage.
Mask identifiers
Click Mask. Real names become anonymous tokens — T_00001, C_00001. The mapping stays on your device.
Send to AI safely
Copy the masked version and send to ChatGPT or any AI. No real schema data is transmitted by our app.
Restore real names
Paste the AI's response. Click Restore. Your real identifiers are put back in one click.
Privacy by design
Your data never touches our servers
Every single tool on UnblockDevs runs entirely in your browser. We don't have servers that process your data — because we don't need them.
Try AI Schema MaskerNo server-side processing
All computation happens in your browser using JavaScript. No request is made to our backend.
No logging or telemetry
We don't log your SQL schemas, JSON payloads, API keys, or any other sensitive input.
GDPR, HIPAA, SOC 2 safe
Suitable for regulated industries. Nothing is shared with third parties, ever.
Open architecture
Built with Next.js. You can inspect every network request and verify no data leaves your device.
