    description
    Blekline protects sensitive data in prompts before it leaves your browser. 🛸
    
    Teams are moving fast with AI, but one pasted secret, customer identifier, or internal detail can create a real security and compliance risk. Blekline adds a real-time protection layer across your AI workflows by intercepting prompt sends, masking sensitive entities, and applying workspace policy controls before transmission.
    
    Use Blekline Shield to keep execution speed high while reducing accidental data leakage in day-to-day AI usage.
    
    What Blekline Shield does:
    - Masks sensitive context before prompt send
    - Applies workspace-level policy controls (strict mode, keyword rules)
    - Supports secure prompt workflows across major AI platforms
    - Connects extension activity with Blekline webapp security controls
    - Helps teams operationalize AI usage with safer defaults
    
    Use Blekline on supported AI platforms to:
    - Prevent accidental sharing of names, emails, IDs, keys, and other sensitive data
    - Enforce prompt safety policies at the point of use
    - Keep a consistent protection layer across tools your team already uses
    - Reduce manual prompt sanitization overhead for engineering, operations, and security teams
    
    Why teams use Blekline:
    Blekline is designed for organizations that need practical AI adoption with security guardrails. Instead of relying on users to remember what not to paste, Blekline introduces policy-driven controls directly in the workflow.
    
    This gives teams a cleaner path to scale AI usage without increasing unnecessary risk exposure.
    
    Who this is for:
    - Engineering teams handling internal code and secrets
    - Revenue/operations teams working with customer and account context
    - Security and compliance stakeholders who need stronger AI usage controls
    - Marketing teams handling IP's and client secrets
