Algolia Recommend is a robust, API-first recommendation engine built to help digital businesses deliver intelligent product and content suggestions to users in real time. It combines user behavioral signals (such as clicks, views, purchases) with catalog metadata (titles, descriptions, attributes, images) to generate highly relevant and personalized suggestions. Launched in May 2021, it has rapidly matured to include advanced models, merchandising controls, and visual similarity features.

At its core, Algolia Recommend supports multiple recommendation models: “Related Products” suggests items that are similar to what a user is viewing; “Frequently Bought Together” surfaces complementary items often purchased in the same session; “Trending Items” highlights currently popular choices; and “Looking Similar” uses image recognition to find visually similar products. In addition, the engine supports trending facet values, allowing suggestions based on hot categories or facets.

One of the strengths of Algolia Recommend is its flexibility and control. Developers and merchandisers can apply Recommend Rules to shape results according to business needs—boosting or suppressing items, pinning specific products, or enforcing filters (e.g. inventory thresholds). The service is engineered for performance, serving recommendations via low-latency API calls. You can integrate easily with front-end frameworks using Algolia’s UI libraries for JavaScript and React.

To set it up, one first prepares product and event data, then triggers a training process (which may take up to a couple of hours). The engine retrains periodically, allowing recommendations to stay fresh. The tool also handles cold start situations by relying on content-based similarity until enough behavioral history is available.

From an operational standpoint, Algolia Recommend offers a free tier allowing up to 10,000 recommend requests per month under the Free Plan. Beyond that, paid usage is billed per recommendation request (commonly $0.60 per 1,000 requests).  For large or enterprise users, customizable quotes and enterprise plans are available.

Because it is tightly integrated with Algolia’s broader search and discovery ecosystem, teams already using Algolia for search can add recommendations without significant architecture changes. The shared indexing and analytics infrastructure help unify search and recommendation logic. This makes Algolia Recommend a natural extension for organizations seeking to enhance user engagement, increase average order values, and boost conversion through personalized suggestions embedded at every user touchpoint.
