About

Redacta

Read full description

Redact patient identifiers before they ever reach an AI assistant – entirely on your iPhone. Clinicians and medical writers increasingly paste notes into ChatGPT and Claude. Redacta makes the safe version one tap away: it finds names, NHS numbers, dates of birth, record numbers, emails, phone numbers and addresses, and replaces them with neutral tokens like [NAME_1] and [NHS_NUMBER_1]. Nothing leaves your device. HOW IT WORKS • Paste or type clinical text, choose a mode, and tap Redact • Copy the safe, tokenised text into any AI assistant • Keep the token map to put the real values back into the AI's reply ON-DEVICE BY DESIGN • No network connection, no accounts, no analytics • Nothing is uploaded or stored – a truthful "Data Not Collected" • Token maps live in memory only and are never written to disk THREE MODES • Clinical – NHS numbers (checksum-validated), names, dates of birth, record IDs • General PII – emails, phone numbers, postcodes, cards, addresses • HIPAA Safe Harbor – the strictest set, including every date and age MORE WAYS TO REDACT • Share Sheet – redact selected text from Mail, Safari, Notes and more • Scan – photograph a letter and pull out the text with on-device OCR • Reinstate – paste the AI's reply and restore the real values • Shortcuts & Widget – "Redact clipboard with Redacta," hands-free WHO IT'S FOR Junior doctors, clinicians, medical writers, NHS staff, and anyone who wants to use AI with sensitive text without breaking confidentiality. Redacta is free. Automated redaction is best-effort – always review the output before sharing it. Redacta is a privacy utility, not a medical device, and does not provide medical advice.
