HOW IT WORKS

One line of code. Five layers of protection.

[01]
Wrap

Wrap any client — svitch.wrap(openai.client). Context and tools carry across every model.

[02]
Shield

PII is detected and redacted before the prompt ever leaves your codebase. Aadhaar, PAN, UPI, GDPR entities, and more — on by default.

[03]
Route

Each query is complexity-scored. Routine work is auto-routed to a cheaper model — up to 80% off.

SVITCH SHIELD · LIVE DEMO

Paste any text. Watch PII disappear.

Runs entirely in your browser — the same engine runs server-side, before any model sees a single token.

INPUT
THE SDK

One import.
Three superpowers.

Drop Svitch in front of the SDK you already use. No prompt rewrites, no proxy config, no new mental model.

WHAT'S INSIDE SVITCH
SVITCH SHIELD● LIVE

PII redaction before the prompt

Detects Aadhaar, PAN, UPI, IFSC, IBAN, SSN, and 15+ more entity types — and strips them out before data reaches any model. Reversible, deterministic, logged.

SVITCH ROUTER● LIVE

The right model for every query

Routine queries score low and route to cheap models; hard ones escalate. You set the ceiling, Svitch spends under it — cutting model cost up to 80%.

SVITCH TRACER● LIVE

A tamper-proof record of every decision

Every prompt, redaction, route and response is hashed into an append-only chain. Break a link and the whole trail flags. Export for any auditor.

SVITCH ENCLAVE○ COMING SOON

Inference that never leaves your perimeter

An encrypted on-premise enclave runs open models inside your own network over a WireGuard tunnel. Zero egress — sensitive data stays put.

SVITCH LEDGER○ COMING SOON

Consent, recorded on a shared ledger

A Hyperledger consent chain records who agreed to what, when. Prove lawful basis for every data subject — ready for DPDP grievance officers.
