The problem

Articles with formulas often show blurry images or broken text, which hurts readability and search ranking.

The solution

Formulas render as text with KaTeX, illustrations are generated from TikZ into SVG, and cover images are created automatically. Each article ends with a call to practice, a course, or a consultation.

How it works

What happens, step by step, from the user's point of view.

  1. 01

    The writer drafts an MDX article

    Articles are written as plain text with formulas inside, then stored alongside the website code.

  2. 02

    Illustrations drawn from code

    Pictures such as graphs and shapes are written in TikZ, and a script turns them into sharp SVG images.

  3. 03

    Covers are made automatically

    A script creates a cover image with the title and main illustration, used when the article is shared.

  4. 04

    The reader opens the article

    Formulas display as crisp text through KaTeX, with a table of contents to jump to any section.

  5. 05

    A topic-matched call to action

    Each article ends with a fitting next step: tutoring, self-study practice, or a free consultation when no product fits.
