Vector Explore
Retrieval Augmented Generation (RAG)
The fastest way to understand RAG is to run it.
Download a public-domain novel, chunk it, embed it, spin up a local vector DB, and watch every step including retrieval and augmented generation happen in front of you, as you "chat with the novel". Classic build to learn.

Track Slack
Model Context Protocol (MCP) Apps
Got a Slack full of forgotten promises?
You said you’d follow up. Then Slack happened. Track Slack reads your sent messages, uses LLM reasoning to identify commitments, and serves a live dashboard inside ChatGPT or Claude. Just say "track my promises" to your agent, keep your promises, and boost your credibility.

Sorted Signals
Workflow Automation (n8n)
An experiment in agentic journalism.
A test-bed newsletter run on a self-hosted n8n community instance — Sorted Signals pulled the latest AI developments from RSS feeds, read websites with Jina, and drafted a weekly article. Supabase for storage. OpenRouter for inference.

Just Talk
Agent Skills
"Just talk to the AI" is good advice — until you have to do it all over again.
Just Talk keeps the conversation going with targeted questions until you’ve said everything you need to say, then stores it all in a structured, reusable format. Your context is there the next time you need it. Who knew a plain old text file could be so powerful?
