Optimizely is a digital experience platform combining web experimentation (A/B testing), feature flag management, content management, and commerce — with AI features that accelerate experimentation programme velocity and surface insights from test results.
Stats Engine, Optimizely's proprietary statistical engine, uses Bayesian statistical testing to reach significance faster and more reliably than traditional frequentist testing — enabling earlier winner declaration and more experiments per period without inflated false positive rates.
AI experiment recommendations suggest which page elements and variations are most likely to improve conversion based on historical test patterns across the platform — helping experimentation teams prioritise testing ideas rather than guessing which tests to run next.
Project Ideas AI generates experiment hypotheses from website analysis — scanning page structure, user behaviour patterns, and competitive context to suggest what to test and what variation hypotheses might improve performance. This AI-assisted ideation is particularly valuable for teams who struggle to generate sufficient experiment ideas to fill their testing roadmap.
Content management with AI helps teams manage and personalise content at scale — the Optimizely CMS integrated with experimentation enables testing content variations and personalising experiences based on test results and user segments without separate CMS and experimentation tools.
Optimizely AI runs as ml platform software built around data and text workflows. Users typically start with a prompt, upload, or connected data source, and the underlying model handles the heavy lifting before returning a result you can refine or export. It's available on web, api, and sdk.
The capabilities that matter most for teams evaluating Optimizely AI.
Bayesian statistical testing reaching significance faster than traditional frequentist methods — enabling earlier winner declaration and more experiments per period without inflated false positives.
Scans page structure and behaviour patterns to suggest experiment ideas — addressing the ideation bottleneck that limits experimentation programmes to the few ideas teams can manually generate.
A/B testing across web front-end, server-side logic, and APIs — enabling product teams to experiment on any system component alongside traditional webpage element testing.
