How to choose

What data sources can it connect to?

Choose a platform that can connect to the data sources you need to search.

Compare connectable data sources alongside semantic search and recommendations.

Where does the platform need to run?

Match the deployment options to the way your team plans to use the software.

The board covers web, API, self-hosted, Linux, Android, and iOS availability. An API is a way for software to connect to other software; self-hosted means running the platform on infrastructure you manage.

How should search results be tailored?

Compare semantic search, personalized results, and recommendations against the experience you want to offer.

Search analytics can help you review search activity. Check the feature details for the platform you are considering to see what it provides.

Can I try it before paying?

Check whether the platform offers a free plan or a free trial, and compare the paid starting price where it is listed.

A free plan and a free trial are not the same: a trial lasts for a stated period, while plan terms can differ. Pricing may also be available on request.

Does it need a public API or open-source code?

Check for a public API if the platform needs to connect with other software, and review the licence if you need to read or change its code.

The board marks API availability, open-source code, and a free tier separately. Those marks do not replace checking the terms and capabilities that matter to your setup.

Questions

What is an AI search and discovery platform?

It is software for finding information or products, with features such as semantic search, recommendations, personalized results, and search analytics.

What should I compare when choosing AI search software?

Compare search and discovery features, connectable data sources, deployment options, integrations such as a public API, and pricing.

Do AI search platforms have free plans?

Some offer a free plan, while others list a free trial or paid pricing. Check the terms for the platform you are considering.

What does self-hosted mean for search software?

Self-hosted means running the platform on infrastructure you manage. Check whether that deployment option fits your setup.

What is the difference between an API and open-source software?

A public API lets software connect to the platform. Open-source code can be read or changed under its licence; the two are separate marks.
