AI Ops platform for enterprise personalization and semantic search
Model user behaviour and item relationships to rank what each visitor sees next across home pages, catalogues and content feeds.
Understand intent behind a query rather than matching keywords, so users find relevant items even when their wording differs from your metadata.
Represent users, items and content in a shared vector graph that supports cold-start items and cross-surface consistency.
Feed the retrieval layer into conversational assistants so AI answers cite real inventory, articles or support content.
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.
