Heading Outline Checker
Paste Markdown or simple HTML-ish draft text and see the heading structure before it turns into published web furniture.
Status: Live · Processing: the outline logic runs locally in your browser. Paste a draft, check the detected headings, review hierarchy warnings, and copy a Markdown summary if you need to hand the notes to future-you.
This is not an SEO oracle, an accessibility audit, or an AI editor wearing a tiny lint badge. It just makes the heading outline visible so skipped levels, duplicate section names, missing top-level headings, and multiple H1s are easier to catch.
Heading Outline Checker
Paste Markdown or simple HTML-ish draft text and see the heading structure before you publish it. This checks the outline; it does not rewrite the draft or pretend SEO is solved because a robot counted some hashes.
Privacy note: the outline check runs locally in your browser. Draft text pasted here is not intentionally submitted to CyganLabs, stored in WordPress, or sent to an AI service or third-party endpoint by this tool. Like the rest of the public site, this page may still load normal WordPress, security, analytics, or ad scripts. Do not paste secrets here.
Keep secrets out of drafts anyway. This is a structural checker, not a secure vault, an HTML validator, or an editorial judgment machine.
Supports Markdown headings like # Title through ###### Detail, plus simple <h1>–<h6> tags. Headings inside fenced code blocks should be ignored by the final logic.

Copyable review summary
When to use it
- Before publishing a long-ish Markdown draft, WordPress page, guide, runbook, or documentation note.
- When a draft feels messy and you want to see the structure without rereading every paragraph.
- When headings have been copied through too many editors and the hierarchy may have become soup.
- Before handing a draft to someone else for review and asking them to guess whether the outline makes sense.
- When you need a copyable Markdown outline summary for a ticket, review note, or editing pass.
What it does not do
- It does not rewrite, rename, reorganize, or improve headings for you.
- It does not judge whether the draft is good, persuasive, accurate, readable, accessible, or search-optimized.
- It does not inspect live WordPress pages, parse every possible HTML edge case, validate links, or fetch destination URLs.
- It does not replace Markdown Cleaner; this checks structure, while Markdown Cleaner cleans formatting sludge.
- It does not store draft text, create accounts, add tool-specific telemetry, or intentionally submit your content. Normal site scripts may still load around the tool page.
