Yellow Pill

Inspiration

I personally cannot wait for my own personal Jarvis from Iron Man or Samantha from Her. I think we're finally close enough, and I think pretty soon, personal context will be the only moat. I find a ton of value in content on platforms like X, but I had a hunch that when steered right, AI can already generate great content that is useful and valuable for people if it's clever about how it stores its memory on that person.

What it does

It lets a user sign in with their X account, parses their public profile, asks them a bunch of questions about themselves, and populates a feed of useful and relevant content for that user.

How we built it

Basically there are three main components: 1) the "core profile" of the user, which is a manifest of everything you need to know about someone to know what makes them tick and what's important to them, and 2) the generation jobs that run in the background to populate a feed of fresh and relevant content, and 3) the frontend web app that lets a user log in and browse and interact with their feed.

Challenges we ran into

It took more prompt engineering than I anticipated (as it always tends to) to get it to produce valuable, relevant results. I had a breakthrough when I realized I was overly compressing the user's initial input, and adding a "meta" layer to the user's profile that analyzed things like their word choices, and the subtleties and nuances of their answers produced significantly better results.

Accomplishments that we're proud of

The app works smoothly and generates content that I genuinely found personalized and useful.

What we learned

I learned a ton about walking the tightrope of storing enough consistent memory to produce good results without bloating every request.

What's next for Yellow Pill

I'm going to make it into an iOS app, and use protocols like x402 to introduce novel payment models where users can pay per token instead of a traditional monthly subscription. I also plan to generalize the core personal model piece (which I call a Soul Manifest), and build other things on top of that, including a personal assistant. I also want to tap more data sources into this project—for example it should know your schedule, and deliver a morning briefing at the top of your feed, perhaps as a podcast in the voice of a celebrity you know and love.
