Product Guideline

Development Doc



Is my data secure with PublicAI?

Yes, PublicAI prioritizes data security and privacy. We have implemented robust measures to ensure customer data remains safe and secure.

Our platform features multiple layers of security, including:

  • Encryption of data in transit and at rest
  • Access controls to limit data access

We also enforce strict policies and procedures for employees and annotators to follow best practices in data security and privacy.

How does pricing work? Can I just pay-as-I-go?

There are two types of service options. If you choose the PublicAI marketplace, you can get a free tier that provides a complimentary amount of annotation, and you can pay-as-you-go for anything exceeding that amount. This means you only pay for what you use.

To access additional features and enterprise capabilities, you can upgrade to PublicAI Pro for Enterprise.

Do I get charged based on the number of annotators / labelers working on my project?

No! Every service option comes with unlimited annotation team members. You only get charged for the work that your annotators complete.
