Live egress pipeline simulator
Raw Prompt
Untrusted user input
Type sensitive data or pick a scenario. TrustNode Core tokenizes PII into a vault, routes safe placeholders to the LLM, then re-identifies on the way back to the user.
Masked Prompt (To LLM)
Vault tokens + Brand Guard — reversible PII only
Masked prompt will appear here.
Raw LLM Output
Model echoes vault tokens (never raw PII)
Run the pipeline to simulate the LLM response.
Final Unmasked Output (To User)
unmaskPii restores vault PII · competitors stay blocked
Run the pipeline to see PII restored for the end user.
Extension live · API waitlist open
Mask PII in ChatGPT, Claude, and your apps before data leaves the browser — or route production workloads through the TrustNode API.

Local runtime cube
Local SDKs and Browser Extensions attach directly at the source — policies compile to native runtime checks.
Egress & redaction plane
TrustNode enforces outbound rules — PII and sensitive entities are strictly tokenized into a local vault before egress.
One policy surface
External LLMs & partner APIs
Only masked graph-safe payloads cross the boundary.
Observable. Audited. Compliant.
Compliance surface
Map egress controls to major privacy frameworks without shipping raw payloads upstream.

* The TrustNode SDK may call home for license verification and policy bundles only. Raw prompts and payloads stay on your machines.
Data never leaves your infrastructure. Redaction runs inside the TrustNode Core runtime.
Deterministic scanners and policy graphs keep egress checks under single-digit milliseconds.
Map controls to GDPR, CCPA, HIPAA, and COPPA without shipping raw payloads upstream.
