Crin AI

The platform offers interactive, visual lessons that illustrate how modern language models transform input text into tokens, embeddings, and vectors. Each node in a lesson displays the actual data flow—tokenizers split text into colored pills, embedding layers render high‑dimensional vectors as heatmaps, and vector nodes present bar‑chart representations—allowing users to see real values rather than placeholders. Lessons can be viewed in three modes: a visual overview, a simple plain‑English analogy, and a deep technical definition, with the ability to switch modes without losing progress.

Designed for developers and anyone interested in learning AI fundamentals, the curriculum covers basics such as tokenization, attention, and embeddings before moving toward building applications. Progress is saved to a user account, so learners can resume exactly where they left off across multiple sessions. The content is free, requires no prior AI knowledge, and is organized into self‑contained lessons that can be started in any order.
