About First Principles
Simple words. Clear thinking.
What this tool does
First Principles helps you examine a question, find the most useful answer, and choose one next step. The name reflects a method of thinking: separate reliable facts from assumptions and reason from the foundations of a problem.
How answers work
AI answers use an OpenAI text model through fal.ai and OpenRouter. The first sentence presents the key answer; the supporting explanation identifies an assumption, an action, and a condition that could change the answer. The tool has no live web search in this version and cannot verify current facts.
Examples and limits
The examples on this site are written illustrations. They are labeled as examples and are not live AI responses or proven customer outcomes. The tool can be wrong and does not replace domain expertise or your own judgment.
Background
The philosophical background is discussed in the Stanford Encyclopedia of Philosophy’s Aristotle’s Logic article. Our short practical method is an adaptation for everyday problem solving, rather than a complete account of Aristotle’s theory.
