Runs on your hardware · never touches the cloud

Redact sensitive documents in minutes — without a byte leaving your walls.

MorettaMask finds the personal data in your PDFs, scans and Office files automatically, lets your team confirm every redaction by hand, and delivers a clean, audit-proof document — all running locally, on your laptop or your own server.

Hours back, every day

What takes an hour of manual blacking-out takes minutes. Upload, let the engine surface every hit, confirm, export — done.

Your data never leaves

No cloud, no third parties, no telemetry. The AI model runs locally. Your documents never leave the host they were uploaded to.

Automated — with a human in the loop

The engine proposes; your reviewer decides. Nothing is redacted until a person confirms it — full control, no black box.

How it works

Four steps, one private workflow

From a stack of raw documents to a clean, permanently redacted file — without anything ever reaching an outside server.

STEP 01

Upload

Drop PDFs, scanned images or Office files — up to 20 at once. Built-in OCR makes even scanned pages searchable, so nothing hides from detection.

STEP 02

Detect

A local language model plus pattern matching finds emails, names, phone numbers, personnummer and IP addresses — colour-coded and grouped, page by page.

STEP 03

Review

Your team ticks exactly what to redact, with the full document in view. Draw manual redactions, add notes, compile several files into one — you stay in control the whole way.

STEP 04

Deliver

Export a flattened PDF with the selected data permanently removed — not hidden, gone. The originals never left your machine, and every action is written to a hash-linked audit trail.

Private by architecture

Private by design, not by promise

MorettaMask isn't a cloud service with a privacy policy. It's software that runs where your data already lives — so there's nothing to trust us with in the first place.

Runs on your hardwareA laptop or an on-prem server — your call. Deployed with one Docker command.
Local AI modelPII detection runs on a local model — no external API calls, no prompts sent anywhere.
Documents never leave the hostNo uploads to a cloud, no telemetry, no analytics. Works fully offline.
Hash-linked audit chainEvery action is recorded in a tamper-evident, SHA-256 hash-linked ledger.
Encrypted, installation-bound sessionsSave and resume work in encrypted session files that only open on the installation that made them.
Real redactionSelected data is flattened out of the file — removed, not just visually covered.
Who it's for

Built for teams that can't send documents to the cloud

Anyone who handles sensitive records and is bound by GDPR — where "just upload it somewhere" was never an option.
