πŸ‘‹ πŸ”Ž Hello Cognition: Search Engine for Developers

Hello answers technical questions with simple explanations and relevant code snippets from the web.

TL;DR: Hello searches and understands technical sources for you, giving you actionable explanations and suggestions for your technical problems.

Hey YC, we’re Michael and Justin - excited to launch Hello Cognition today!

Problem

Software engineering runs on ad-hoc know-hows - the most valuable information is either in technical documentation or scattered around discussion boards and blogs. Google is too broad and shallow of a search tool to be great at suggesting actionable technical solutions. Understanding information about a complex technical problem still involves a lot of manual time and effort.

Solution

Hello is a search engine that extracts understanding + code examples from technical sources, bringing you information you can immediately act upon to make progress on the problem you’re working on.

Our Story

For our honors theses at UT Austin, we researched prototypes of large generative language models that can answer complex questions by combining information from multiple sources. Training a sequence-to-sequence language model (T5 derivative) on our custom dataset designed for factual generation yielded much better results with less hallucination. After creating this prototype, we started actively developing Hello with the idea that searching should be just like talking to a smart friend.

How it works

When you submit a query, we pull and rerank raw site data from Bing, then extract understanding with our proprietary large language models. For extracting and ranking code snippets, we use BERT-based models. We finally use seq-to-seq transformer models to simplify all this input into a final explanation.
