RESEARCH-GRADE SIGNAL

Human preference data, at scale

Run controlled experiments at scale and export reproducible datasets linking language to behavior.

WHERE HUMAN DATA FALLS SHORT

Rigor doesn’t scale, until now

Surveys lose context. Lab studies do not scale. Social data is noisy. echo captures reasoning and preferences as they form in conversation, while preserving experimental structure.

PROOF IN PRACTICE

Built for audit and replication

Define protocols, randomize variants, and measure outcomes. Export full reproducibility materials alongside the data, including prompts, cohorts, exclusions, and metrics.

BUILT FOR ANALYSIS

Structure that preserves meaning

You get raw language and the context that produced it – prompts, treatments, cohort tags, and outcome labels. That means you can study mechanisms and heterogeneity without flattening everything into a score.

DROP-IN WORKFLOW

Build to fit your methods

Bring your hypotheses and designs. echo runs experiments in real conversations and exports data alongside protocols and metadata needed for analysis.

Design

Define arms, cohorts, and metrics.

Run

Launch in-chat experiments at scale.

Measure

Capture preferences with outcome labels.

Export

Export data with reproducibility materials.

YOU’RE IN CHARGE

Privacy-first controls, research-grade governance

Set controls for retention, cohorts, exclusions, and exports. echo minimizes sensitive data and preserves clear audit trails.
