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.
Which tagline resonates most?
Add a real human-in-the-loop to your agent or product with one call. Ground truth labels, subjective judgment, A/B picks, content checks, whatever a model can't decide on its own. Sign up free and get a $5 trial credit — no card required.
See how it integratesAnswer 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 earningModels trained on synthetic data drift from reality. GetABrain wires your AI straight to the ground truth, one call at a time.
AI-generated training data creates feedback loops and reinforces bias. Real human judgment is the signal your model is missing.
When models evaluate models, mistakes stack. Human evaluators break the loop with calibrated, context-aware feedback.
Is this headline compelling? Is this voiceover warm? Some questions only a person can answer.
Everything you'd build to crowdsource human feedback, already built and battle-tested.
From zero to real human answers in your pipeline, in minutes.
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.
We route your request to verified, quality-scored people who fit your targeting. Five-layer bot detection keeps answers genuinely human.
Typed responses that match your schema, each with quality metadata and worker tier. Drop them straight into your app.
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.
Give Claude, Cursor, or any MCP client the power to ask real humans, no code. Perfect for vibe coders and agents.
