A paid, ad-free search engine that answers to its users
Subscriptions replace advertising, so there are no sponsored results, affiliate links, or data sales influencing what you see.
Rank any website up or down, pin favorites, or block domains entirely so your results match your own standards.
Append a question mark to get an AI answer above the results, or chat with the Assistant for deeper tasks with sources included.
Restrict searches to categories like forums or news, or jump straight into a specific site's own search with shortcuts.
Red-team and evaluate AI agents before they reach production
Adversarial evaluation of agents to surface unsafe, non-compliant or unreliable behaviour before they run against real users and real money.
Measure and track how much fine-tuning private models with LangTrain improves accuracy for your specific domain.
Verify that agent responses are repeatable and reliable enough for regulated workflows such as clinical, lending or claims decisions.
Evaluate agents that work across text, voice, vision and other modalities rather than text alone.
