AI explained in plain words
Short explainers on the ideas behind AI, written for people who do not work in tech: what AI agents are, how to read benchmark scores, what RAG means, and how we score the tools on this site.
- Benchmarks lie. Here is how to read them anyway (). A model topping a leaderboard tells you less than you think. What the numbers measure, what they miss, and when to trust them.
- How we score every AI tool (). The number on every tool page isn't a vibe. Here's exactly what the Solthar Score measures. And what it deliberately ignores.
- AI agents, explained. And why 2026 is their year (). Everyone's shipping “agents.” Most people can't say what one actually is. Here's the honest version.
- RAG is not a product. It is a plumbing decision (). Retrieval sounds like a feature you buy. It is really a set of unglamorous choices about chunking, ranking and what to do when nothing matches.
