In plain words
YC Idea Matcher is a dev tool that lets users submit a business idea and receive a list of similar companies from the Y Combinator portfolio. It uses semantic search powered by OpenAI embeddings and Neon Postgres to understand the context and intent behind queries, rather than simple keyword matching. The tool helps entrepreneurs and developers explore related YC companies to their own concepts, making it useful for market research, competitive analysis, and understanding the startup landscape.

But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself.

Brandon and I are not LLM experts and started the project a few months ago because we wanted to understand better how the generation process works.

Recently we came up with a fast way to generate text that matches a regex (https://blog.normalcomputing.ai/posts/2023-07-27-regex-guide...). The basic idea is simple: regular expressions have an equivalent Deterministic-Finite Automaton (DFA) representation. We…
