Free AI SEO tool

Score a passage on how citable it reads to an AI answer engine.

Paste a single paragraph and get a 0-100 citability score broken down into directness, self-containedness, concreteness, sentence length, and passage length, with specific rewrite tips.

How to use this tool

  1. Paste a single paragraph or passage into the text box, or click Load example to see a sample.
  2. Click Analyze passage to run the heuristic scoring in your browser.
  3. Review the overall 0-100 score and the five labeled sub-scores in the panel on the right.
  4. Read the detail line under each sub-score to see exactly what was measured, such as average sentence length or concrete-marker density.
  5. Work through the rewrite tips, which point to the specific weak sub-scores found in your text.
  6. Revise the passage and re-analyze until the sub-scores you care about improve.

This is a heuristic scored entirely in your browser, not a live AI citation scan. Nothing you paste is sent to a server. It estimates how quotable a passage looks structurally — it cannot know whether any AI system will actually cite it.

Questions

Frequently asked questions

Useful context for applying this tool to your site.

What does the citability score actually measure?

It combines five pattern-based sub-scores — directness, self-containedness, concreteness, sentence length, and passage length — into a single weighted 0-100 number. Each sub-score looks for a specific textual pattern associated with passages that read as standalone, quotable claims, such as opening with a concrete subject instead of a pronoun.

Is this a live scan of how AI systems cite my content?

No. This is a deterministic heuristic that runs entirely in your browser against the text you paste; it does not fetch a URL, call a model, or send anything to a server. It cannot know whether any specific AI system will actually cite a given passage, and a high score is not a guarantee of citation.

Why did my passage score low on self-containedness?

The self-containedness check flags passages whose first word is a pronoun that depends on unincluded context, such as "This," "It," "They," "These," or "That." Replacing that opening word with the actual subject usually raises the score, since the passage can then be read and understood on its own.

What counts toward the concreteness sub-score?

The tool counts numerals, percent and currency symbols, and capitalized proper-noun-like tokens per 100 words as a rough proxy for specific, quotable facts versus vague generalities. It's a surface-level pattern match, not true named-entity recognition, so unusual capitalization or acronyms can occasionally skew the count.
