## Getting started

Set up your account and run your first scan.

- [Run your first scan](https://winstonai.ai/help/run-your-first-scan): Paste text or upload a file, check the credit cost, and read your results in a few seconds.
- [Supported file formats and limits](https://winstonai.ai/help/supported-file-formats): What you can upload on each plan, how long a single scan can be, and how to get the cleanest result from a file.

## Scans & results

Read scores and highlights with confidence, and share what you find.

- [How to read your human score](https://winstonai.ai/help/how-to-read-your-score): What the 0–100 score means, what it doesn't, and how each result band should change what you do next.
- [What the sentence highlights mean](https://winstonai.ai/help/sentence-highlights): Red, yellow and unmarked sentences, the probability behind each one, and why a few highlights in human writing are normal.
- [Why human writing can be flagged as AI](https://winstonai.ai/help/why-human-writing-gets-flagged): False positives are rare but real. These are the kinds of writing most likely to trip a detector, and what to do when it happens.
- [Talking with a writer about a flagged result](https://winstonai.ai/help/discussing-a-flagged-result): A fair, five-step way for teachers and editors to follow up on a low human score without accusing anyone.
- [Share a report or download it as a PDF](https://winstonai.ai/help/sharing-reports): Send a read-only link to a scan, control what it shows, and export a PDF for your records.

## Plagiarism

What we compare against and what the numbers mean.

- [How the plagiarism check works](https://winstonai.ai/help/how-plagiarism-check-works): What we compare your text against, what a check costs, and how to keep quotes and references out of the score.
- [Reading a plagiarism report](https://winstonai.ai/help/reading-a-plagiarism-report): What the similarity percentage means, the three kinds of match, and when a high number is perfectly fine.

## Billing & credits

Credits, plans, invoices and cancelling.

- [How credits work](https://winstonai.ai/help/how-credits-work): What each kind of check costs, when credits roll over, and what happens if a scan fails.
- [Cancel or change your plan](https://winstonai.ai/help/cancel-or-change-your-plan): Upgrade, downgrade or cancel from your dashboard, and know exactly when each change takes effect.
- [Invoices, receipts and refunds](https://winstonai.ai/help/invoices-and-refunds): Download invoices, add a company name or tax ID, update your card, and know when a refund is possible.

## Account & security

Signing in, privacy and deleting your data.

- [Delete scans or your account](https://winstonai.ai/help/delete-scans-or-account): Remove a single scan, clear your whole history or close your account, and how long each one takes.
- [Reset your password or change your email](https://winstonai.ai/help/sign-in-and-password): Get back into your account, change the email you sign in with, and keep your account secure.

## Teams

Shared workspaces, roles and pooled credits.
