from blindfold import Blindfold
bf = Blindfold()

# 1. Tokenize PII
prompt = "My email is [email protected], card 4532-7562-9102-3456"
safe = bf.tokenize(prompt)
# "My email is <EMAIL_1>, card <CREDIT_CARD_1>"

# 2. Send to any LLM
response = openai.chat.completions.create(
    model="gpt-4o",
    messages=[{"role": "user", "content": safe.text}]
)

# 3. Restore original data
result = bf.detokenize(response.choices[0].message.content, safe.mapping)

result = bf.tokenize_batch(
    ["Patient: Sarah Jenkins, SSN: 123-45-6789", "Contact [email protected] or +1-555-0123"],
    policy="hipaa_us"
