Lyra is a fully private AI platform with human verification built in. Every challenge solved trains your AI — no Google, no surveillance, no dependencies.
Five specialized products, one unified platform. Each one captures a different type of human intelligence and feeds it directly into Lyra.
Modern human verification that replaces reCAPTCHA. Challenges test real cognitive ability — and every response trains your AI.
Users identify AI-generated vs human-written text. Builds a labeled dataset of AI detection examples — the most valuable data on the internet right now.
Humans describe images, icons, and UI in natural language. Generates rich alt-text training data that teaches Lyra to see and describe the world.
Spatial and physical reasoning challenges. Teaches Lyra how the real world works — gravity, momentum, cause and effect — through human intuition.
Users classify the tone, intent, and emotional register of text. Builds a human-labeled sentiment and intent dataset that makes Lyra emotionally intelligent.
The same strategy Google used with reCAPTCHA to train its image AI — except you own the resulting model.
Unlike reCAPTCHA, you own every data point. At 100,000 examples you can fine-tune a 125M parameter model for ~$50. At 1,000,000 examples, you train one from scratch.
One line of HTML. Works like reCAPTCHA — drop it into any form, any framework.
Every challenge solved is a human-labeled training example saved to your pipeline.
JSONL training records in instruction, completion, and RLHF formats — ready for fine-tuning.
At 10K examples, start LoRA fine-tuning. At 1M, train from scratch. Your AI, fully independent.
Two lines of HTML. Works with React, Vue, Django, Laravel, WordPress — any stack. Verify on your backend with a single POST.

reCAPTCHA fingerprints users across the entire web. Lyra sees nothing it shouldn't — your users stay yours.
Google used reCAPTCHA to train its image AI for free. With Lyra, the resulting model is entirely yours.
No more fire hydrants. Lyra's challenges test real cognitive ability — users find them interesting, not frustrating.
Same API surface as reCAPTCHA. Site key, secret key, one POST to verify. Works with every framework.
