# Redact PDF AI — Features

> AI-powered PII redaction with batch upload, interactive Studio editor, multi-language OCR, and a REST API.

## AI-powered PII detection

Eight PII categories detected automatically:

- **Person** — full names, first/last names, signature-block references
- **Email** — standard addresses plus common obfuscation patterns
- **PhoneNumber** — international (E.164) and national formats, validated
- **Address** — multi-line postal addresses (Swiss, EU, US/UK formats)
- **Organization** — company names, hospitals, government bodies (entity-aware, doesn't need Inc/Ltd/SARL suffix)
- **Date** — DD.MM.YYYY (Swiss/EU), MM/DD/YYYY (US), ISO, written-out
- **IBAN** — ISO 13616 validated (check digits + country code)
- **CreditCard** — Luhn-validated PAN (Visa, Mastercard, Amex, Discover)

Multilingual: 100+ languages via Azure AI Language with automatic language detection.

## Batch uploads and ZIP download

Drop a folder of dozens or hundreds of PDFs into the uploader. Track per-file progress. Download the entire processed batch as a single ZIP. Email notification when complete.

## Interactive Studio editor

After AI detection, refine results in the Studio:

- **Click and drag** to create manual redaction boxes
- **Click to delete** existing detections (false positives)
- **Highlight mode** — mark areas without redacting them, for review-only workflows
- **Page rotation** — rotate scanned pages before redacting
- **Mobile-friendly** — touch-optimized for tablets and phones

## Excluded Terms (never auto-redact)

Add words or phrases to your account's "Excluded Terms" list — they will never be auto-masked across future uploads. Useful for your own company name, brand terms, or specific clients you've cleared for visibility.

## Always-Redact Terms

The opposite list: words or phrases that will always be redacted on every upload, even if the AI doesn't flag them as PII. Use for institution-specific identifiers (medical record numbers, internal case IDs, policy-number prefixes).

## Mask persistence

Once you've redacted a document, the mask positions are saved to the database. Reopen the document in the Studio later to fine-tune your redactions — no need to re-run AI analysis.

## Irreversible redaction

PDFs are rasterized (converted to images) and then masked. Output has no hidden text layer, no metadata referencing the original content, and no way to copy-paste recovered text. Even forensic PDF analysis won't recover the redacted content.

## REST API

Programmatic access via async jobs:

- `POST /v1/jobs` — submit a job (with `X-API-Key` and optional `X-Idempotency-Key`)
- `GET /v1/jobs/{id}` — poll job status
- `GET /v1/jobs/{id}/documents/{docId}` — download outputs

Retention modes: `ephemeral` (default, deletes originals after processing) or `studio` (keeps originals + masks for review).

## Team workflows

Business and Enterprise plans support multi-user organizations. Invite team members, share batches, and manage roles centrally.

## Demo mode

Try without signing up. The home page demo uploader processes one document for free, with the redacted output emailed to you. Useful for one-off use or evaluation before committing to an account.
