The Clipboard Firewall for the AI Era.

Redact sensitive data from your clipboard before pasting. Local-First Architecture: all redaction and processing occur 100% on your machine—your data never leaves your device for that workload.

All processing is local. Nothing is sent to external servers.

Three Pillars

Security and workflow, without sending a byte off your machine.

Ghost Mode

Clipboard Firewall

Enable Ghost Mode to activate background monitoring and real-time redaction. Sensitive data is intercepted and sanitized before it can be pasted—keeping credentials, keys, and PII off your clipboard when you need it most.

On-device trust boundary

Local-First Architecture

All file redaction and processing occur 100% on your machine—your data never leaves your device for that workload. No cloud scrubbing of your content; no telemetry on your text. HTTPS is limited to features you choose (e.g., Pro activation via Supabase/Stripe) plus OS / Microsoft Store services.

Auto-Copy, Smart Trim, 30s Wipe

Enhanced Workflow

Auto-Copy sends redacted output to the clipboard in one click. Smart Trim keeps only high-signal lines (errors, critical, context). The 30-second Clipboard Wipe clears redacted content automatically so nothing lingers.
