Our autocomplete is the best introduction to your site's search

Constructor.io provides shockingly good suggestions optimized to increase conversions

Icon suggestions

Search suggestions at the speed of thought

Autocomplete must respond instantly, or it makes your entire site feel slow and kills conversions. We built our autocomplete to return results in a fraction of a second.

Icon misspellings

User misspellings shouldn’t cost you money

Our patent-pending Phonetic Intelligence Engine provides high quality results, even for misspelled queries. That means your conversion rate never suffers from misspellings.

Icon machine

Machine learning optimizes results in real-time

Advanced machine learning algorithms learn from your users to continuously update result rankings, optimizing conversions and search revenue.

Personalization

Personalized results

Don't serve lowest-common-denominator results to all users. Constructor.io can personalize suggestions by returning individual users' recent searches as suggestions, dramatically improving user experience for repeat purchases.

Icon results

Images, categories & search suggestions

We’ve built our autocomplete with flexibility in mind. Send your users directly to product results, suggest common searches, or recommend suitable category pages. We also support displaying product images and descriptions in search results.

Icon global

Global infrastructure, localized search

Our architecture is distributed across the world to ensure your users see instantaneous results, regardless of location. That’s crucial given we support all languages, including those with 2-byte characters and non-Western alphabets.

Two-minute integration

Our goal is to be your easiest vendor integration ever.
