Your AI is guessing. Humans know.

AI models trained on synthetic data drift from reality. GetABrain connects your AI to the ground truth.

Synthetic Data is Unreliable

AI-generated training data creates feedback loops and reinforces biases. Real human judgment provides the signal your model needs.

Hallucination Feedback Loops

When AI evaluates AI, errors compound. Human evaluators break the cycle and provide calibrated, context-aware feedback.

No Ground Truth for Subjectivity

Is this headline compelling? Is this image appealing? Some questions have no algorithmic answer—only human opinion.

The difference is real

Stop building fragile human feedback pipelines from scratch.

Without GetABrain

  • Recruit and manage your own crowd workers
  • Build quality control from scratch
  • Handle payments, disputes, and fraud
  • Wait days for survey results
  • Parse unstructured response formats

With GetABrain

  • One API call to reach quality-scored humans
  • Built-in 5-star rating system and tier enforcement
  • Stripe-secured payments with automatic routing
  • Get structured responses in minutes
  • Receive typed JSON matching your query schema

Frequently asked questions

Everything you need to know about integrating human feedback into your AI pipeline.

GetABrain uses a prepaid balance model. Fund your account via Stripe, then each query deducts the bid amount per response from your balance. A 15% platform fee is included. No subscriptions, no minimums beyond $0.05 per response. You can enable auto-reload to keep your balance topped up automatically.
Response times depend on query complexity and worker availability. Simple queries like yes/no or multiple choice typically receive responses within minutes. Complex queries like video reviews or detailed text analysis may take longer. You can set expiration times and required response counts to control timelines.
Every worker has a quality score (1-5 stars) based on requestor ratings and acceptance rates. Workers are tiered (Bronze, Silver, Gold, Platinum) and you can set minimum quality requirements per query. Our 5-layer bot detection system ensures all responses come from verified humans. Workers below 1.5 stars are automatically suspended.
Absolutely. GetABrain.ai is built API-first specifically for AI agents and applications. Use standard REST API calls with your API key to submit queries and retrieve structured JSON responses. No browser or UI interaction needed. Your AI agent can integrate human feedback directly into its pipeline.
Workers earn per response, with bonuses for higher quality tiers (up to 20% for Platinum). Earnings are accumulated in their balance, and payouts are processed via Stripe Connect with a $10 minimum. Transfers take 7-10 business days. Workers complete identity verification and tax forms through Stripe during onboarding.
Yes. Query content is treated as confidential. Workers agree to strict confidentiality terms and are prohibited from sharing, screenshotting, or disclosing any query content. Violations result in immediate termination. All data is encrypted in transit and at rest. We never sell personal data.
