Context-Aware Analysis

The difference: Traditional dictionaries give you every possible meaning. Aletheia gives you the right meaning for what you're reading.

Why Context Matters

Words are shape-shifters. The same word can mean completely different things depending on where it appears. Traditional dictionaries list all possible definitions and leave you to figure out which one applies.

This works fine for simple words. But for words with multiple meanings, technical jargon, or domain-specific usage, you end up scanning through numbered definitions trying to match one to what you're reading.

Aletheia eliminates this guesswork. By analyzing the text surrounding your selection, it delivers the meaning that actually fits your context.

How Aletheia Works

When you select a word or phrase, Aletheia captures three things:

This context bundle is sent to an AI model that understands language the way humans do: in context. Instead of pattern-matching to a static database, it reasons about what the word means here, in this sentence, on this page.

The result is an explanation tailored to your reading, not a generic dictionary entry.
