Integration & Platform Notes

Brilliant is a consumer and institutional SaaS platform rather than a developer API product. The following is what is publicly known about its technical surface:

Platforms: Available as a web application and mobile app (evidenced by 100,000+ app store reviews)
AI Tutor (Koji): Embedded conversational/guided AI that scaffolds problem-solving without answer disclosure — architecture details are not publicly documented
Adaptive engine: Personalizes content sequencing based on assessed learner mastery; specific data model or API details are not publicly available
Privacy & compliance: kidSAFE certified, making it suitable for deployment in children's educational contexts with associated privacy obligations met
Institutional access: District-level licensing is available on request, suggesting a managed account or admin layer exists for bulk deployments

Note: Brilliant does not publish a public developer API or webhook documentation. Institutions seeking integration details (e.g., LMS compatibility, SSO, roster sync) should contact Brilliant directly for district pricing and onboarding specifics.
