Hot Shot's Secret: an AI that knows every product

Buyers of a lubricants and additives brand ask which product fits their engine, what a symptom means and how much fluid a vehicle takes. We built an assistant that answers from the brand's own information and recommends the right product.

What did BetterAI build for Hot Shot's Secret?

An AI product expert. It searches the brand's own information, calls custom tools for product search, FAQs, categories, symptoms, vehicle and engine details and fluid capacity, and answers in plain words with a product recommendation. It appears as a chat assistant on the website.

What problem does an AI product expert solve?

A brand with many products gets the same questions again and again: which one fits my engine, what does this symptom mean, how much fluid does my vehicle take. Answering them one by one takes expert time. The assistant answers from the brand's own information, at any hour.

What we built

Four parts.

Knowledge search

Answers from the brand's own information.

Documents are split into chunks and searched with OpenAI embeddings and Chroma through LangChain. Contextual compression keeps each answer focused.
