AI Content Detector — Check if Text is AI-Generated Free

PDF to Word

Basic text version: this extracts the readable text from a text-based PDF and saves it as an editable Word (.doc) file you can open in Microsoft Word or Google Docs. It works on PDFs that contain real text — scanned documents and complex layouts (columns, tables, images) won’t carry over.

Merge PDF

Pick two or more PDFs and they’ll be combined into a single file, in the order you selected them. Everything happens in your browser — your files are never uploaded.

    Compress PDF

    Two ways to shrink a PDF. “Re-save” tidies the file structure without touching quality. “Strong” rebuilds every page as an image at your chosen quality — much smaller for scan-heavy PDFs, but text becomes part of the image.

    JPG to PDF

    Turn one or more images (JPG, PNG, WebP and more) into a single PDF — one image per page, sized to fit the page.

      Split PDF

      Pull pages out of a PDF: either download every page as its own one-page PDF, or extract just the page range you need into a single new file.

      PDF to JPG

      Renders every page of your PDF as a JPG image and downloads them one by one (page-1.jpg, page-2.jpg…). Best for documents up to about 50 pages.

      Word to PDF

      Runs on a connected serviceConverting a Word document to PDF with its layout, fonts and tables perfectly intact needs a document-conversion service. This tool activates on the live SavyTools website — it isn’t connected yet, and no file you choose here is uploaded or converted.

      Word Counter

      Character Counter

      Detect AI-generated text free online with SavyTools’ AI content detector, which analyses patterns in writing and gives an AI probability score. If you want to check if text is AI generated — an essay, an article, or a submission you are reviewing — the score works as a screening aid, not a final verdict, since formal human writing can sometimes be flagged too. Please note: this tool activates on the live site once it is connected to a detection service.

      Please note: this tool activates on the live site once it is connected to a detection service. The tool panel on the page will show its status plainly, and nothing here pretends it is already running.

      How to Use

      1. Open the AI content detector at the top of this page and paste the text you want to check.
      2. Run the detection and wait for the analysis to complete.
      3. Read the AI probability score and any highlighted sections.
      4. Use the result as one signal among others, not as proof on its own.

      Frequently Asked Questions

      How accurate is AI detection?

      Detectors give probabilities, not certainties. Longer, natural texts give more reliable signals, while very short texts are much harder to judge and should be treated with extra caution.

      Which AI models can it catch?

      The detector scores patterns that are common in AI-generated writing rather than naming one specific model. Results are estimates, and newer models can be harder to spot than older ones.

      Can it give false positives?

      Yes. Formal, technical, or heavily edited human writing is sometimes flagged as AI-generated. Never use a single score alone to accuse someone or to reject a piece of work.

      Tips

      Check longer passages rather than single sentences, since short texts give the detector very little to work with. Treat the score as one signal: a high score does not prove a text is AI-written, and a low score does not prove it is human. Combine the result with what you know about the author and the writing before drawing any conclusion. This tool runs through a connected detection service on the live site.
