DocLint

Catch broken links, outdated screenshots, and style violations in your docs.

● The Problem

Technical documentation rots. Links break, screenshots show old UIs, API examples use deprecated endpoints, and style guide rules are ignored. Docs drift from reality faster than anyone can manually audit.

● The Solution

A CI tool that lints your documentation. Checks for broken links, validates code examples, compares screenshots against live UI, and enforces style rules (terminology, formatting, voice). Runs on every PR.

Competitive Landscape

Vale handles prose linting. Markdownlint checks formatting. Nothing combines link checking, code validation, and screenshot comparison in one tool. The bundled solution is the value.

Why Now?

Developer experience is king. Bad docs cost real revenue in churned developers. AI makes screenshot comparison and style enforcement practical at scale.
