Blackline AI

Blackline AI is a document redaction platform that combines AI-based detection with manual review controls to identify and permanently remove sensitive information from PDFs and image files.

Key features and functions include:

AI-Based Sensitive Data Detection
The platform automatically identifies categories of sensitive information within uploaded documents, including names, addresses, email addresses, IBANs, and monetary amounts, allowing users to redact by category rather than searching manually.

Optical Character Recognition
Built-in OCR extracts text from scanned PDFs, JPGs, and PNGs, including multi-page documents, enabling detection and redaction of sensitive content in non-searchable files.

Manual Redaction Controls
Users can review AI-suggested redactions, remove false positives, draw manual redaction areas, or redact full sections or pages before finalizing a document.

Permanent, Flattened Export
Redacted documents are exported as flattened PDFs in which the underlying text is removed rather than visually obscured, so redacted content is not selectable, copyable, or recoverable.

Browser-Based Processing
Document rendering and OCR occur locally in the user's browser. Only extracted text is transmitted to a third-party AI service for detection; original files are not persistently stored.

Watermarking
Documents can optionally be watermarked with a custom or default logo at one of three density settings as an additional step alongside redaction.

Business and Team Features
Paid plans include managed folders for automated redaction, an optional four-eyes approval workflow, role-based access, and audit logging.

Integrations
The platform offers a Chrome browser extension and a desktop application with folder-based automation for high-volume use. Additional integrations are available with HubSpot, Salesforce, Pipedrive, Slack, DocuSign, Gmail, and Outlook, along with broader connectivity through Zapier.
