This is a prototype built in half a day as part of Nesta's Generative AI Exploration Day, with Anna & Clare from Best Begginings (the charity behind the Baby Buddy app).
The premise was to build a custom chatbot which responds to questions using referenceable content from Baby Buddy, also mimicking their style of writing which is concise and easy to read.
This website has access to a subset of Baby Buddy's content on labour & childbirth. When a user asks a question, we first perform a semantic search using vector representations of the text known as embeddings. This fetches the 5 most similar Q&A examples from the Baby Buddy data. We then input these examples into a prompt to GPT-3.5, along with the users's original question and some additional instruction, resulting in the chatbot's response.
