Snowglobe Core Features
Realistic User Personas
Snowglobe creates highly realistic synthetic user personas that mimic real human behavior, providing diverse and authentic conversation data. This helps in identifying edge cases and improving chatbot reliability.
Scalable Simulation
Run hundreds of conversations in minutes across varied intents, personas, tones, goals, and adversarial tactics. This scalability ensures comprehensive testing coverage.
Judge-Labeled Datasets
Generate labeled test datasets from simulated conversations, ready for export to evaluation tools. These datasets cover real behavior across multiple dimensions, enhancing chatbot performance.
Fine-Tuning Data Generation
Produce high-signal training data, including judge labels, preference pairs for DPO or reward models, and critique-and-revise triples for SFT, all exportable in clean JSONL format.
QA at Release Speed
Conduct hundreds of realistic conversations per build to catch issues early, saving test suites for regression and tracking error rates to prevent production failures.
