How it works

The flow should be simple enough to use quickly and structured enough to produce a useful publishing decision.

Step 1

Paste the real text

Drop in the chapter, sales copy, or article section you actually want to judge instead of instinct about clarity.

Step 2

Review the formula spread

See Flesch-Kincaid, Gunning Fog, Coleman-Liau, ARI, and reading ease together so one number does not mislead the decision.

Step 3

Check reading-level fit

Translate the scores into grade level and reading age so the text matches the audience you are actually trying to reach.

Step 4

Spot density before editing gets heavier

Use the benchmark view to catch complexity, sentence length, and readability drift before the manuscript moves deeper into production.

Step 5

Move into the next editorial pass

Once readability is in range, turn the cleaned text into stronger packaging, positioning, or formal editing work.

FAQ

Readability questions authors usually ask before they edit further

Next step

Once the text is reading at the right level, the next move is improving the book around it.

Readability is one part of manuscript quality. The stronger follow-up is turning that clarity into sharper editing, packaging, and conversion copy.
