Why AI-Generated Markdown Breaks
AI models like ChatGPT, Claude, and Gemini produce Markdown that looks correct in their own interfaces but breaks when pasted into editors like Obsidian, Notion, or VS Code. Common issues include unclosed code fences, missing blank lines around headings, and inconsistent list markers.
AI Markdown Cleaner applies a set of deterministic, rule-based fixes entirely in your browser — no server, no AI rewriting, just clean, predictable output.

Markdown Best Practices for AI Workflows
Always fence code blocks
Wrap code with triple backticks and specify the language for proper syntax highlighting.
Use consistent heading levels
Don't skip from H1 to H3 — maintain a logical hierarchy for better readability.
Limit consecutive blank lines
Most Markdown renderers treat 2+ blank lines the same as 1. Keep it clean.
Standardize list markers
Stick to - for unordered lists. Mixing *, +, and - can confuse some parsers.
