Cognitiva
Cognitiva is a browser-based tool that turns existing markdown into a clean, navigable documentation reader. Paste any markdown content and get a paginated 3-column layout (sidebar for pages, main content area, and a right-side table of contents) that you can download as a self-contained HTML file.

Exploring the app
My role
Solo project. Built the renderer, template system, and download functionality from scratch using vanilla HTML and JavaScript, with no build tools or framework. Also wrote Playwright test suites.
Context
Built to solve the problem of making existing markdown documentation actually readable and navigable without spinning up a full docs platform. The goal was maximum simplicity: no framework, no CI pipeline, one tool that works in the browser.
