**TL;DR**

Kart transforms the product discovery experience for the most innovative e-commerce companies. At a fraction of the cost and time, we build customized AI shopping assistants like Amazon Rufus, trained to answer any question on your catalog.

**Ask**

We would love:

*   any leads to brands or e-commerce shops that would benefit from a better assistant
    *   stores with multiple brands are awesome, i.e., Best Buy
    *   we are mainly in the electronics/furniture/fashion space, but happy to help any store
*   follow us on [Linkedin](

**Problem: E-Commerce Search is changing. Amazon Rufus is coming.**

Top brands, like Amazon, are all investing in sales assistants on their websites. This is no coincidence: ChatGPT and Perplexity have shown how valuable chatbots can be for search. AI shopping assistants have been shown to boost conversion rates by 15%.

Product search is just one sector, and a very large one at that. A poll conducted by Anderson Consulting showed that 62% of online customers would buy more products if live chat and support were available. A survey by Invesp shows that chatters tend to spend 60% more per purchase.

**Solution: We build your product search assistant!**

Until now, human sales assistants have always been coveted but too expensive to maintain for non-luxury brands. Now, we build agents for your online store for a fraction of the cost.



Our team was formerly employed at Cohere and Tiktok Shop, competed in International Linguistics Olympiads, and won the recent Amazon Alexa Prize Social Chatbot challenge. We held a demo on [ for electronics and helped 10,000+ users with their latest electronic purchases. Here’s what our assistant can do for you:

1.  **Give product recommendations:** Trained on your catalog, we know what’s popular and other trending products across the industry. We help customers find exactly what they need, keeping our recommendations as objective as possible while maximizing sales conversion rate.
2.  **Answer non-product questions:** The current search is bad with nuanced questions. We handle all these cases: your customers can now ask questions ranging from _best father’s day gifts_ to a _summary of reviews for the latest samsung oled monitor._

Whenever you are ready to transform your online store, please contact us at [founders@kart.ai.](mailto:founders@kart.ai) We can’t wait to transform the future of shopping with you.
