A human-intelligence API for the AI era

Real human judgment,
on tap for your AI.

GetABrain is the fastest way to plug real people into whatever you're building. Your agent, app, or script asks a question; quality-scored humans answer in minutes, as structured JSON. Or flip it around and get paid to answer questions yourself.

For everyone

People who want to earn on the side

Answer short questions from AI on any device, whenever you have a minute. Free to join, no resume, no interview. The better your answers, the higher-paying the requests you unlock.

Start earning

Your AI is guessing. Real people know.

Models trained on synthetic data drift from reality. GetABrain wires your AI straight to the ground truth, one call at a time.

Synthetic data is unreliable

AI-generated training data creates feedback loops and reinforces bias. Real human judgment is the signal your model is missing.

AI judging AI compounds errors

When models evaluate models, mistakes stack. Human evaluators break the loop with calibrated, context-aware feedback.

Subjectivity has no algorithm

Is this headline compelling? Is this voiceover warm? Some questions only a person can answer.

Skip the pipeline. Make the call.

Everything you'd build to crowdsource human feedback, already built and battle-tested.

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

Three steps to human intelligence

From zero to real human answers in your pipeline, in minutes.

1

Ask via API, SDK, or MCP

Send your question, response type, and bid. Pick from 16 response types, or have your agent call the MCP server with no code at all.

2

Matched humans respond

We route your request to verified, quality-scored people who fit your targeting. Five-layer bot detection keeps answers genuinely human.

3

Get structured JSON back

Typed responses that match your schema, each with quality metadata and worker tier. Drop them straight into your app.

Plugs into whatever you're building

Three ways in. Start with the MCP server in your AI coding tool, reach for an official SDK, or hit the REST API directly. Same humans behind all three.

MCP server

Recommended

Give Claude, Cursor, or any MCP client the power to ask real humans, no code. Perfect for vibe coders and agents.

npx @getabrain/mcp-server

Official SDKs

Typed clients for Node and Python. Create queries and read responses in a couple of lines.

npm i @getabrain/sdk
pip install getabrain

REST API

No dependencies. Standard HTTP with an API key and secret. Works from any language or runtime.

POST /api/v1/queries

16 structured response types

Every type returns validated, schema-compliant JSON, from a quick yes/no to a worker-recorded voice note, video, or photo. Here's what people see.

Create a free account and confirm your email and phone. Takes about two minutes, on any device.

2

Answer what fits you

3

Cash out via Stripe

Earn per response. Build a high rating to unlock the highest-paying requests, then withdraw to your bank.

Start earning, it's free

Higher ratings unlock higher pay. No credit card, ever.

Trusted on both sides of the marketplace

5-layer bot detection

CAPTCHA, behavioral analysis, timing checks, IP reputation, and response-quality scoring keep answers human.

Quality scoring

A 5-star rating system with automatic tiers. Consistently low scores get suspended; high scores earn more.

Stripe-secured money

Payments and payouts run through Stripe, with identity verification via Stripe Connect for workers.

Confidential by default

Workers agree to confidentiality before they see any query. Data is encrypted in transit and at rest.

Questions, answered

For builders integrating human feedback and for people earning on the side.

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.
Sign up free, verify your email and phone, and answer short questions from AI applications that match your profile, on any device. You earn per response. A higher quality rating unlocks higher-paying requests, and requestors can pay premiums for workers in their target demographic or top rating tiers. Earnings accumulate in your balance; cash-outs go through Stripe Connect once you reach the $10 minimum (payout processing is rolling out now — your balance is safe and becomes withdrawable the moment payouts go live).
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.

Two ways in. Pick yours.

Wire real human intelligence into your AI, or get paid to be that intelligence. Both start free.

No credit card to start — a $5 trial credit covers your first queries. Fund your balance only when you need more.
