GeraWitness vs Scale AI
Scale AI labels training data and evaluates AI models before deployment. GeraWitness provides human oversight for live AI-initiated transactions — when an agent books a service, makes a payment, or hires someone, a reviewer can verify it before it executes. The two tools operate at different points in the AI safety stack and are used together by teams that need both pre-deployment evaluation and runtime oversight.
At-a-glance comparison
| Dimension | GeraWitness | Scale AI |
|---|---|---|
| Primary function | Runtime oversight of live AI-initiated service transactions | Training data annotation and pre-deployment AI evaluation |
| When it operates | Live — during active AI agent transactions | Pre-deployment — before models are in production |
| Output | Approve / flag / halt individual transactions | Labelled datasets, model evaluations, RLHF feedback |
| Primary buyer | Service platforms deploying AI agents in high-stakes verticals | AI labs and enterprises building or fine-tuning models |
| Regulatory angle | EU AI Act human oversight layer for high-risk AI systems | AI evaluation for model safety — different compliance layer |
| Integration point | GeraNexus protocol + any service platform exposing agent actions | Data pipelines and model training infrastructure |
| Risk tiers | Built-in risk classification (low/medium/high/critical) per action type | Task difficulty and quality tiers for annotation |
Frequently asked questions
What is the core difference between GeraWitness and Scale AI?
Scale AI is a data annotation and AI evaluation platform — it labels training datasets and helps companies evaluate AI model outputs before deployment. GeraWitness provides human oversight for live AI-initiated transactions in the real world — when an AI agent books a home service, hires a worker, or makes a payment, a GeraWitness reviewer can verify the action before it executes.
Does Scale AI review live transactions?
Scale AI focuses on training data pipelines, model evaluation, and pre-deployment testing. It does not provide a runtime oversight layer for AI agents executing real-world transactions. GeraWitness operates at the transaction layer — reviewing and approving or flagging agent actions in real-time.
What types of actions does GeraWitness review?
GeraWitness is integrated into the GeraNexus protocol and reviews AI-initiated actions across Gera services: bookings, payments, hire requests, cancellations, and service-delivery verifications. High-risk or above-threshold actions route to a human reviewer before execution.
Who performs reviews on GeraWitness?
GeraWitness uses a distributed pool of trained human reviewers. Reviews are assigned based on the service category, risk tier, and language of the action. Reviewers are verified, rated, and held to SLA targets. Scale AI also uses human annotators for their labelling workflows.
How does GeraWitness help with EU AI Act compliance?
The EU AI Act requires human oversight for high-risk AI systems, particularly those affecting employment, essential services, and credit. GeraWitness provides a documented human-in-the-loop layer with audit trails, risk tier classifications, and reviewer accountability records that directly support compliance reporting.
