    Capabilities

    Every pattern of personalization, one index

    Content-Based Filtering

    Encode item attributes as vectors and find semantically similar items in real time. "More like this" for products, articles, videos, and music, without requiring user history. Works from day one of launch.

    Collaborative Filtering

    Encode user behavior sequences as vectors using Item2Vec or similar models. Find the nearest-neighbor user vectors and recommend items those users interacted with. Personalization that improves with every action.

    Cold-Start Handling

    New users and new items get recommendations immediately via content-based similarity, no interaction history required. As interactions accumulate, the system smoothly transitions to collaborative signals.

    Sub-5ms Response

    Every millisecond of recommendation latency is a lost engagement. Endee serves the nearest-neighbor item and user vectors in under 5ms, inline with page load, not as a deferred async fetch.

    Filtered Recommendations

    Constrain recommendations to in-stock items, region-specific catalogs, or content the user hasn't seen. Filters run inside the ANN search, no post-retrieval filtering that degrades precision.

    Cross-sell & Upsell

    Encode cart contents and compare against complementary product vectors. Surface "frequently bought together" and upgrade suggestions in real time, not from pre-computed tables that lag behind catalog changes.
