This page lists every control in the **AI Detection** workflow and says what each one does: the editor and its samples, the **Scan** and **Auto-scan** controls, the four tabs of the **Analysis** pane, the **Export** menu, **Detector settings**, and the **Bulk AI Detector**. It is for anyone who has read [Detect AI-Written Text](/ailyze-docs/analyze-data/detect-ai-written-text.md) and wants to know what a specific setting changes. AI Detection is free on every plan, needs no account, and runs in your browser; nothing you paste or upload is sent anywhere. The word floor and per-scan limits are on [Plans, Limits & Credits](/ailyze-docs/reference/plans-limits-and-credits.md). Last verified against the staging app on 14 October 2026. ## The editor

The sample chips under the editor disappear once you paste your own text.

| Control | What it does | Notes | | --------------------- | ------------------------------------------------------------------------------------------------ | ----------------------------------------------------------------------------------------------------- | | Text area | Paste or type the text to check. | A footer counts the words and says how many more are needed for a result. | | **Scan** | Runs the detector. | Ctrl+Enter (⌘+Enter on a Mac) also scans. | | **Upload file** | Reads a TXT, MD, PDF, DOCX, CSV, XLSX, or XLS file in the browser. | Choosing several files opens the bulk detector. A scanned PDF with no selectable text cannot be read. | | **Clear** | Empties the editor. | | | **Auto-scan** control | Opens the auto-scan popover (below). | Reads **Auto-scan on**, **off**, or **paused**. | | **Try a sample:** | **Human-written sample**, **AI-generated sample**, and **Journalism sample** load example texts. | Hover a chip to see where the sample comes from. | | **Bulk detector** | Opens the Bulk AI Detector. | | | **Scan it anyway** | Appears on long documents, where automatic re-scanning pauses. | | ### Auto-scan | Setting | Options | Default | | ------------------------------------------------------------------ | -------------------------------------------- | ------------------ | | **Re-scan as I edit** | On or off. | On | | **When** | **When I stop typing** or **On a timer**. | When I stop typing | | **Wait … after typing stops** | How long to wait after the last keystroke. | About a second | | **Check every …** | The timer interval, in timer mode. | Fifteen seconds | | **Only after … words change** | How many words must change before a re-scan. | Three | | **Also scan right after a paste**, **Also scan when I click away** | Extra triggers. | Both on | Only the passages you changed are re-run, so a re-scan is usually instant. ## The Analysis pane The pane header shows scan progress with a **Stop** button, then **Export** and the **Detector settings** gear. On a first visit a **One-time setup** card shows the detector downloading; it is cached afterwards and works offline. A language warning appears when the text does not look like English, because the score means nothing on other languages. | Tab | What it shows | | ------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | **Overview** | The gauge with the **AI-generated content probability** and a verdict from **Very likely human-written** to **Very likely AI-generated**; a **Low**, **Medium**, or **High confidence** pill with the reasons on hover; the **Human**, **Mixed**, and **AI** composition bar; the **Most AI-like passage**; the **Across the document** strip, where clicking a band jumps to that text; the **Score distribution** histogram; and text statistics. Below the word floor it reads **Not enough text for a reliable result**. | | **Breakdown** | **Passages** and **Sentence Groups** with their scores, sorted **Highest** or **Lowest**, fifty at a time. | | **Style** | Writing-style statistics measured from the text alone and not part of the score: **Sentence-length variation**, **Vocabulary variety**, **Em-dash, semicolon & colon rate**, and **Stock AI phrasing**, plus the stock phrases and repeated three-word phrases found. | | **History** | A sparkline of this session's scans with **Compare with** an earlier scan, and the scans saved in this browser. **Saved on this device** turns saving off; rows can be pinned, restored to the editor, or deleted. | **Model limitations** under the pane opens the list of caveats: English only, higher false positives for non-native and technical prose, and never a sole basis for a disciplinary decision. ### Export | Item | What you get | | ------------------------------------ | ------------------------------------------------------------- | | **Copy summary** | The verdict and key figures as text, on the clipboard. | | **Download annotated report (HTML)** | The text with its highlights and the analysis, as a web page. | | **Download raw scores (JSON)** | Every passage score, for your own processing. | | **Download summary (text)** | A plain-text summary. | | **Print or save as PDF** | The browser's print dialog. | Every export carries the accuracy warning with it. ### Detector settings

Changing a threshold re-scans at once, so you can watch the composition bar move.

| Setting | What it changes | Default | | ---------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------- | -------------- | | **Count as human below …%** | Passages at or below this score count as human in the composition bar. | A quarter | | **Count as AI above …%** | Passages at or above this score count as AI; everything between the two thresholds is mixed. | Three quarters | | **Flag passages under … words** | A trailing passage shorter than this is marked unreliable. | The word floor | | **Highlighting** | **Heat map**, **Three bands**, or **Off**. | Heat map | | **Detector precision** | **Automatic**, **Balanced**, or **Highest**. The larger build only helps on machines with GPU acceleration and downloads a different model. | Automatic | | **Cached model** → **Clear from this browser** | Removes the downloaded model; it is fetched again on the next scan. | | | **Reset all settings** | Restores every default. | | ## The Bulk AI Detector

Drop the files themselves; a dropped folder is not opened.

| Control | What it does | | ----------------------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | Drop zone and **Choose files** | Add TXT, MD, PDF, DOCX, CSV, XLSX, or XLS files, up to the per-run cap. Extra or unsupported files are skipped with a notice. | | **Scan … documents** | Scores every file: an overall score, a verdict, and a confidence rating. **Stop** halts a run; **Clear** empties the list. | | Summary line | How many were scanned, how many lean AI, how many are not English, and how many failed or were skipped. | | Table | **Document**, **Words**, **AI**, and **Verdict**, sortable, most AI-like first. Click a row to run the full scan on that document with highlighting and the usual tabs; **All documents** returns. | | **Export** | **Download summary (CSV)**, **Download summary (Excel)**, and **Annotated reports**, a ZIP of HTML reports for the documents you opened. | | **Check a single document instead** | Back to the editor. | Batch results stay in the tab and are not saved, so export before you close it. ## Next steps * [Detect AI-Written Text](/ailyze-docs/analyze-data/detect-ai-written-text.md) — how to read a score responsibly. * [Supported File Types](/ailyze-docs/reference/supported-file-types.md) — what the detector can read. * [Plans, Limits & Credits](/ailyze-docs/reference/plans-limits-and-credits.md) — the word floor and per-scan limits.
