Short answer

How can I check my writing grade level with AI?

Your AI uses specific readability formulas to calculate the exact grade level of your text. You'll get precise Flesch-Kincaid or Gunning Fog scores instead of just a vague feeling about how easy your writing is.

Readability outcomes.

Mathematical validation.

The AI processes your text through two distinct mathematical models.

FLESCH

Flesch-Kincaid scores

The AI calculates the Flesch-Kincaid grade level. This tells you exactly what grade level your text matches based on sentence length and syllable counts.

GUNNING

Gunning Fog scores

The AI runs the Gunning Fog index. This provides a different mathematical perspective on how difficult your text is to read.

TARGET

Target alignment

You can compare the calculated scores against your specific requirements. This ensures your content hits the exact complexity level you intended.

HUMAN

Manual adjustments

The AI provides the math, but you decide how to rewrite the text. You remain in control of the actual tone and style.

The workflow

What your AI does when text arrives.

The AI acts as a mathematical validator for your prose.

  1. Analyze text

    Your AI reads the text you provide to prepare for the calculation.

    calculate_flesch_kincaid

  2. Calculate Flesch-Kincaid

    The AI applies the Flesch-Kincaid formula to determine the grade level.

    calculate_flesch_kincaid

  3. Calculate Gunning Fog

    The AI applies the Gunning Fog formula to provide a secondary readability metric.

    calculate_gunning_fog

  4. Report scores

    The AI presents the final grade level numbers directly in your chat interface.

FAQ

How this task behaves.

  • 01

    Can the AI rewrite my text to be simpler?

    No. The AI only calculates the mathematical scores. You must ask your AI to rewrite the text yourself after seeing the results.

  • 02

    Does it work on any text?

    Yes, as long as you provide the text or a file your AI can read.

  • 03

    Can the AI change the grade level automatically?

    No. The tools only provide the calculation. The AI cannot change the text through these specific tools.

  • 04

    Will it delete my original files?

    No. This MCP only reads data to perform calculations. It has no capability to delete or modify your files.

  • 05

    Which formula is more accurate?

    Both are mathematical standards. You can use both to get a more complete picture of your text's complexity.
