Free readability & draft checker

Paste a draft and this checker counts what a reader feels: word count, reading time, average sentence length with the long sentences flagged, paragraph count, subheading coverage and how often your keyword appears. Its plain-language score is labelled an estimate, because that is what it is. The draft autosaves on this device only.

Runs in your browser. Nothing you type is uploaded, sent to a server or stored anywhere except this device. This tool is template- and rule-based — it does not use generative AI, and it will never invent a fact for your post.

What to look at

    Worked example

    The sample draft in the editor is 150 words across two headed sections and eight sentences. Run through the checker exactly as it stands, it reports a one-minute read, two Markdown subheadings, and two sentences flagged for running past twenty-five words — including the one that lists rent, tax and software, which is doing three jobs at once and reads like it. Replace the sample with your own draft and every number moves as you type; close the tab and the draft is still here when you come back, because it never left this device.

    The method

    How it works

    1. It counts, then it points. The numbers are exact counts of your text. The notes underneath point at the two or three things worth fixing first — a checker that flags everything flags nothing.
    2. Sentence length is a signal, not a sentence. A long average usually means sentences doing two jobs at once. Short ones everywhere is its own problem: the post starts to read like a shopping list.
    3. The score is an estimate. The plain-language score uses a standard readability formula based on sentence length and syllables. It is useful for spotting dense patches and useless for judging whether your argument is any good.

    What this tool does not do

    • It does not check grammar, spelling or facts — counts cannot do that work, and the page will not pretend otherwise.
    • Keyword density is reported, not targeted. Writing to a density number produces the kind of post readers can smell.
    • The readability formula was designed for general English prose. Technical, legal or medical writing will score “harder” while being exactly right for its readers.

    No. The counting happens in JavaScript in your own browser, and the draft autosaves to your browser's local storage on this device — the same privacy model as every WorkKitly tool. Clear the draft with the button provided, or clear your browser data, and it is gone.
    The score is an estimate from a standard formula (sentence length and syllables per word), shown on a 0–100 scale where higher reads easier. For a general blog audience, a score in the 60s or above usually feels comfortable — but treat it as a pointer to dense paragraphs, not a grade to chase.
    Because length is where readers quietly give up. A sentence past twenty-five words is not automatically wrong — the checker does not delete or rewrite anything — but each one should earn its length. In practice, most flagged sentences split cleanly into two.
