Smart search means happy visitors

Understand intentions, not just keywords

We've all been there. We know what we're looking for, but can't seem to figure out how to say it. Semsei helps your visitors discover the content they're seeking, even when their queries aren't quite perfect.

Lightning-fast results: Blink and you might miss it! No really, Semsei searches execute in less than a blink of an eye (0-400 ms). But don't take our word for it, give it a try. Sign up and index your own website and you can test it out right here on Semsei.
Set it and forget it: No constant tweaking required. For Hobby users, just point Semsei at your domain, and we'll keep your search results fresh and relevant on a daily basis.
User-friendly: Semsei lets users search in their own words, not yours.
Up and running in minutes: Depending on the size of your domain, you can index your site and be searching before you finish brewing that morning cup of coffee.
