Skyline

✨ Bring your own algorithm for Bluesky ✨

Skyline allows you to create your own AI algo-feeds (or use one of our pre-defined ones). Try it out here!

My goal with this project was to create a social media that makes you happy, not just optimizes engagement.

We have the following feeds:

• One post from each person you follow (let's not forget the shy poasters) 🙈
• Mutuals feed, to keep up with your friends 🤗
• Wholesome-only, to remind yourself of the best in humanity ❤️‍🔥
• What's Hot, but only in your preferred language 🌐
• Make your own algorithm! Just tell the AI what you want to see and what you don't 🤖

The way custom algorithms work in Skyline is via LLM embeddings. You can write a positive prompt "I want to see more of...", and posts matching will be brought to the top, and a negative prompt "I want to see less of..." which decides which posts to push to the bottom.

Ultimately, my interest in bring-your-own algorithm comes down to encouraging more love & kindness in the world. And I found this had a bigger impact than I thought it would! You can try this for yourself: does browsing Wholesome put you in a lighter, better mood than browsing Following?

In the long-term, I imagine safe MDMA-analogs in our coffee and other wild transhumanist stuff as the way, but in the short-term I think we'll be going the memetic route! That means kinder algorithms, kinder chatbots, new secular "religions", etc.

Everyone knows "social media makes you angry" - but maybe the tech is finally here for "social media makes you kinder"?

Getting Started

This is a Next.js project bootstrapped with create-next-app.

First, run the development server:

npm run dev
# or
yarn dev
# or
pnpm dev

Open http://localhost:3000 with your browser to see the result.
