# How to use AuthorText > How to use AuthorText: checking a text, sign-up and login, plans and subscribing through PayPal. - URL: https://authortext.com/en/help - Language: en - Site: AuthorText (https://authortext.com/) A short guide: from checking a text to registering and subscribing. ## 1. Checking a text Open the analyzer page and paste the text into the field on the left. You can also load a text from a link or from a file (PDF, DOCX, ODT, RTF, EPUB, FB2, HTML, TXT, MD): the tabs above the field. Press "Check". On the right you get an overall score (0 to 100) and bars for the separate signals: variation of sentence and paragraph length, stock phrases, connective words, hidden characters and others. Below the score you see the spots in the text with quotes. Click a spot and the text scrolls to the right line. The "Highlight" tab shows such spots right in the text. The "What you could improve" block shows which fragments are written too evenly and how to fix them. In the free mode only a counter is shown; the details open on paid plans. The clean button removes hidden characters and simplifies typography; then you can copy or download the text. If the text is longer than your plan allows, only the part that fits is cleaned and kept. ## 2. Reading the result The score rests on statistical features of the text. From about 50 points a text looks AI-written, and from 70 it is a strong sign. It is a guide, not proof of authorship. On short texts (under a few hundred words) the score is less reliable, and the service says so. Texts of some genres (advertising, social media) are judged more cautiously. The text is sent to the server only for analysis and is not stored. ## 3. Plans and limits Without logging in the free plan applies: up to 3,000 characters, the main signal bars and the first 3 spots with quotes. Paid subscriptions: Basic (€3 a month), Plus (€9.99), Pro (€19.99, with an API key) and Max (€24.99, no limit on the number of checks). They give longer texts, all the spots with quotes, the metrics table and the detailed breakdown. Compare them on the "Plans" page. Which bars are shown is set in "Menu -> Settings". ## 4. Registering and logging in Press "Log in" in the top right corner. There are two ways; pick the one that suits you. A code by e-mail: enter an address, receive a six-digit code (valid 10 minutes) and enter it. No password is needed, and the address is the login. The account is created on the first login. Login and password: choose the "Login and password" tab -> "Create an account", pick a login and a password (at least 8 characters). The e-mail is optional. Both ways can use the same e-mail address: they are two separate accounts. If you do not see the code option, sending mail is switched off at the moment; use login and password. A login lasts about 12 hours. You can log out in the menu. ## 5. Your cabinet Open "Menu -> Cabinet" (after logging in). It shows the sign-in method, the login or e-mail, your subscription (plan, status, date of the next renewal or of the end) and how long the login lasts. The "E-mail and password" card: confirm the address with a code, after which the password can be changed with a code sent to that address. A sign-in by code has no password. If the owner of the service issued the account, its plan is assigned by hand, and subscribing works as for any other account. ## 6. Subscribing and paying Open the "Plans" page, choose a plan and press "Subscribe". If you are not logged in, the login window opens first. You then go to the PayPal page and confirm the subscription there. Payment is through PayPal only. The site never asks for or receives bank-card data. The subscription renews every month until you cancel it. You can cancel at any time in your cabinet: the plan then stays active until the end of the paid period. You can change the plan on the "Plans" page or in your cabinet: PayPal asks you to confirm the change. Questions about payments and refunds: support@authortext.com. ## 7. For programs (API) For requests from your own programs you need the Pro or Max subscription and a key, created in the cabinet. Description and examples: the "For developers" page.
