Looking for a co-founder to change language learning forever
I’m throwing this out because I’ve gone as far as I can as a solo founder without holding myself back. (More info about me in my profile.)

I have an awesome prototype that re-imagines how people learn a language. I think this has a real chance to change the world by making language learning as achievable as learning to read in your first language and as predictable as following a recipe.

I applied to YC last year and got an interview, but it was still early enough in development that I needed to rely on instinct and intuition to answer questions. I’ve finished the initial R&D and am building the final UI for the prototype. The prototype natively supports any pairing between 20+ languages, including English, Japanese, Korean, Chinese, Russian, and many European languages. Practically these pairs are limited by the availability of bilingual dictionaries.

I’ve been meeting with a couple of people a week, mostly language learners, teachers, and tech people, but I am finding people, perhaps unsurprisingly, have a lot of trouble seeing past the curse of knowledge. We’ve all learned a language, so most of us feel qualified to teach it to others without deeply examining our assumptions.

Meeting someone on HN isn’t ideal, but I’m determined to find the right people and I’m willing to improve my chances in any way that seems productive.

What’s my idea?

I’ve studied Japanese for years and constantly wonder, “how close am I to being able to read and understand this book, academic paper, song, or show?” And there isn’t any tool that can answer that question for me.

Natural language processing (NLP) has advanced to the point where I can build something resembling abstract syntax trees (ASTs) for natural language sentences. By indexing the words and original sentences, I can easily track a user’s learning across any number of pieces of content, link to word references like dictionaries, cross-index words to show other examples of usage, create automatic exercises with full context, schedule reviews (SRS), tagging named entities (proper nouns and the like) and provide concrete guidance.

I want to build language servers (natural language LSPs) and integrated language environments (an IDE for language) for individuals. For any content a user adds she will have access to content reader, dictionaries, cross-references, character information (like kanji) if applicable, review exercises, parallel text tools (not machine translation), and sentence shadowing tools.

My prototype takes the books, articles, or web pages you would like to read and creates a detailed index of all the words and sentences; it then finds the fewest sentences that cover all the words and turns those into fill-in-the-blank exercises to study from. You are given real feedback and correction when answering exercises. It also includes an integrated e-reader and dictionaries.

Who do I want to meet?

You must be:

* Deeply curious and technical (but this need not be in programming);

* Willing to ignore established methods/ideas when reality doesn’t match;

* Deeply believe that at every level, the details matter;

* Able to say “No” in order to ship, even for things with obvious immediate value.

I'm currently preparing my YC application for the winter 2023 batch.
If interested, please email me at joshua@solarmist.net. Put "co-founder" somewhere in the subject and include:

1) something awesome you've built

2) why would you be right for this and

3) the best time and way to contact (FaceTime/Zoom/etc) you.

Even if you aren't the right person, please upvote this and help us meet.
