Collaborative decision-making software that helps teams ideate and prioritize faster
Let people contribute ideas without attribution to increase psychological safety and reduce hierarchy bias in brainstorming.
Score each idea on value and effort so the team can spot quick wins and high-impact projects at a glance.
Generate starting ideas against a project goal and let AI rephrase, group or refine existing ideas to speed up sessions.
Ideate and prioritize on your own schedule instead of booking another synchronous meeting.
High-quality human data for AI training, evaluation, and research
Filter participants by detailed demographic, professional, and behavioural criteria and reach narrow or representative samples rather than a generic crowd.
Collect human preference data for model fine-tuning, run safety evaluations and red-teaming, and use a feedback API to plug humans into automated pipelines.
Attention checks, honesty screening, and approval workflows help filter out careless or fraudulent responses before you analyse results.
Publish a study and begin collecting responses quickly, with tooling that supports screening, quotas, and longitudinal designs.
