For teams & enterprise

Redact hundreds of documents — without ever storing an original.

Blackline AI is more than an editor. Give your team AI-assisted folders that redact automatically, enforce four-eyes review, and produce a signed audit trail. Everything runs in the browser — we never see your files.

Built for teams that redact every day.

Save hours per file, remove human error, and keep every review defensible.

Managed folders

Drop files into a mailbox. Rules decide what gets redacted — names, IBANs, signatures, custom terms.

AI-assisted, fully automatic

OCR + entity detection on every page, tuned to the categories you enable per folder.

Four-eyes review

Optional approver workflow. Nothing leaves the folder until a second pair of eyes signs off.

Zero storage by design

Originals are processed in-browser and never uploaded. Redacted output only lives 24h in a private, per-team bucket.

Save hours per stack

A 40-page contract review drops from 25 minutes to under 1 — audit log included.

Role-based access

Owners, approvers, processors. Every action is logged with actor, time and document hash.

How a managed folder works

  1. Step
    1. Configure once

    Pick categories (names, addresses, IBANs, signatures…), assign members and choose direct download or 4-eyes review.

  2. Step
    2. Drop files

    Team members upload PDFs or images. OCR, detection and permanent rasterisation run locally.

  3. Step
    3. Approve or download

    Direct mode returns a flat PDF instantly. Review mode notifies an approver with a signed 24h link.

  4. Step
    4. Prove compliance

    Every submission, approval and rejection is written to an immutable audit log with SHA-256 hashes.

Security first

Our security guarantees

  • Originals never touch our servers — processing runs in your browser.
  • Redacted PDFs are permanently flattened; text under bars is unrecoverable.
  • GDPR-friendly. EU hosting, DPA available on request.
  • SSO, custom roles and audit log export on Enterprise.
Enterprise & white-label

Need Blackline inside your own system?

For large enterprises, groups and vendors we offer a REST API and a white-label build. Integrate our redaction engine seamlessly into your existing platform — no user has to leave your product. Custom domain, your logo, your colors, your terms of use.

REST API

One endpoint to redact PDFs, images or plain text. OpenAPI 3.1 spec, live keys, sandbox, per-org rate limits.

Seamless integration

Drop-in into DMS, CRM, ticketing or claims systems via API, S3/Azure Blob bridge or a signed email gateway.

White-label UI

Embed the editor with your logo, colors and domain. Users never see a third-party brand.

On-premise / VPC

For banks, insurers and public sector: private deployment inside your own cloud account or data center.

Special requirements for larger enterprises? We have an adequate solution — from a single API call up to a fully branded platform in your VPC.
