Ghost 5.2 Mini and Pro are live

  • New

    Ghost 5.2 Mini is now available

    Ghost 5.2 Mini is now the default lightweight humanizer model, built for fast, natural rewrites across everyday writing.

  • New

    Ghost 5.2 Pro adds stronger coherence and readability

    Ghost 5.2 Pro is tuned for more coherent structure, smoother flow, and better readability than the Mini model.

  • Improved

    Updated humanizer model lineup

    The humanizer model selector now includes the Ghost 5.2 generation while keeping previous-generation Ghost 5.1 and Ghost 4.6 options available under Legacy.

More reliable results and faster matching

  • Fixed

    Accurate humanized word counts

    Humanized results now show the correct word count.

  • Fixed

    More reliable sentence highlighting

    Sentence highlights now stay better aligned with your text.

  • Improved

    Faster result processing

    Humanizer and scanner results now load more smoothly.

More 5.1 capacity and clearer pricing

  • Improved

    5.1 model servers upgraded for more users

    We improved the 5.1 humanizer server capacity so more users can process text at the same time with smoother availability during busy periods.

  • New

    New Starter, Plus, Pro, Business, and Scale plans

    We refreshed our pricing so every plan shows the exact daily limits up front. Starter includes 50 humanizations/day, Plus includes 150/day, Pro includes 350/day, Business includes 800/day, and Scale includes 2,000/day. Paid plans support up to 5,000 words per input.

  • Improved

    Upgrade prompts now show real daily limits

    When you reach a daily usage limit, upgrade messages now show concrete plan limits instead of multiplier-only copy, making it easier to choose the right plan.

  • New

    Major language support on the 5.1 model

    The 5.1 humanizer now supports major world languages — including German, Spanish, Portuguese, French, Italian, Dutch, Chinese, Japanese, and more. Paste text in your language and get natural, undetectable output without switching to English first.

  • Improved

    Support now opens live chat directly

    The dashboard Support button now opens Intercom live chat immediately, with your account details attached automatically so our team can respond faster.

Cleaner output, smoother highlights

  • Fixed

    Humanizer no longer cuts sentences mid-thought

    Resolved an edge case where longer inputs could be truncated before a sentence was fully rewritten. Your output now consistently finishes every sentence it starts.

  • Fixed

    Reliable sentence highlighting

    Fixed an issue where some sentences weren't being highlighted after humanization. Every rewritten sentence is now properly mapped and visible in the UI.

Easier to read, still undetectable

  • Improved

    Better readability on the 5.1 model

    We tuned the 5.1 humanizer to produce cleaner, more natural prose — fewer awkward phrasings, better flow, and less friction for your readers.

Scanner v2

A sharper, more accurate AI detector

  • New

    V2 scanner is live

    Our AI detector has been upgraded to V2 — significantly more accurate at identifying AI-written text and more consistent across different writing styles and lengths. Expect fewer false positives and sharper confidence scores.
