Hi team — my name is [PERSON_1] ([EMAIL_1]). I called from [PHONE_1] about order [ORDER_ID_1]. You still have my card on file ending 4242, expiring 08/28. Shipping address is [ADDRESS_1]1 6XE. Please cancel before the charge hits my Amex [PHONE_2] 56789.

Rehydrated response 03

Hi Ada, thanks for reaching out. I found your order #A-884217 has been cancelled. A confirmation is on its way to ada.lovelace@analytic-engines.com.
The model replies with tokens. peyeeye.ai swaps them back — client-side if you like.

02 / FLOW

Four calls. One clean round-trip.

Redact before the model, rehydrate after. Tokens are deterministic within a session, random across sessions.
Step 01 · Client

Send the raw prompt

Your app calls /v1/redact with the user's text. TLS 1.3, optional client-side pre-hashing.

// your app
peyeeye.redact({ text: userPrompt, locale: "en-US" })
Step 02 · peyeeye

Detect & tokenize

Hybrid detector (regex + ML NER) identifies 62 entity types. Each value is replaced with a stable placeholder like [PERSON_1].

{ redacted: "Hi [PERSON_1]…", session: "ses_7fA2…", entities: 14 }
Step 03 · LLM

Prompt the model

Forward the redacted text to OpenAI, Anthropic, Gemini, your fine-tune — anywhere. The model never sees a real name, number, or address.

anthropic.messages.create({ model: "claude-*", messages: [...] })
Step 04 · Client

Rehydrate

Pass the reply + session back through /v1/rehydrate. Tokens become real values again.

peyeeye.rehydrate({ text: llmResponse, session: "ses_7fA2…" })
03 / API

Two endpoints. SDKs for every runtime.

Idempotent, versioned, streaming-friendly. Wrap it or call it raw — up to you.

Opinionated defaults.
Escape hatches for everything.

The SDK wraps both endpoints into a single .shield() call that works with your existing LLM client. Or call /redact and /rehydrate yourself.

  • Streaming SSE with partial-token buffering
  • Deterministic pseudonyms within a session, random across
  • Stateless AEAD-sealed sessions — we never see your mapping
  • Custom detectors from a regex or a handful of examples
  • Allow-lists and per-org policies
  • Self-hosted via Docker Compose — same image as our cloud
# 1. Redact PII before sending to your LLM
curl -X POST https://api.peyeeye.ai/v1/redact \
  -H "Authorization: Bearer $PEYEEYE_KEY" \
  -H "Content-Type: application/json" \
  -d '{"text": "Hi, I\'m Ada. Email: ada@example.com", "locale": "en-US"}'

# → { "redacted": "Hi, I'm [PERSON_1]. Email: [EMAIL_1]", "session": "ses_…" }

# 2. After LLM replies, rehydrate
curl -X POST https://api.peyeeye.ai/v1/rehydrate \
  -H "Authorization: Bearer $PEYEEYE_KEY" \
  -d '{"text": "Hi [PERSON_1], we emailed [EMAIL_1].", "session": "ses_…"}'

Your domain has PII we don't know about.
Show us what it looks like.

Paste a few real examples of the PII you care about. peyeeye infers a detector and runs it against your test text, live — no training job, no model tuning, no ticket to data science.
