Writing tools for humanizing, paraphrasing, grammar and plagiarism checks.

Savings opportunities available through GPTinf coupon codes

GPTinf bundles writing tools with free access and paid word allowances. Annual billing lowers the effective monthly rate, while the free tier lets you try the workflow before subscribing. Lite includes 5,000 humanizer words and 2,500 paraphraser words; Pro increases those allowances to 25,000 and 12,500. For repeated edits, Pro includes re-humanize and selective rephrase, which preserve the word budget when used on existing output. Unlimited removes the humanizer word cap. These routes serve different needs: an annual commitment, a smaller allowance, or revisions that avoid spending more words on the same text.

Eligible products and services

Service categories frequently on promotion

GPTinf offers Lite, Pro and Unlimited subscriptions with monthly or yearly billing. The selected plan sets the writing allowance and access to advanced editing features; the billing cycle sets the payment cadence. Lite includes unlimited plagiarism checks, grammar checks and Fix All Errors. Pro adds selective rephrase and re-humanize, alongside priority email support. Unlimited includes the Pro features and early access to new features. A paid subscription combines these tools rather than requiring a separate subscription for each checker. The annual option keeps the chosen plan's features and monthly allowance while lowering its effective monthly rate.

Services usually excluded from promo codes

GPTinf adds sales tax to purchases where required, so tax belongs alongside the subscription amount in the final payment. Paid allowances also distinguish the tools: Humanizer processing draws on its monthly budget, while plagiarism, grammar and detector checks do not spend that pool. A yearly subscription does not carry unused humanizer words into later billing months. Lite and Pro are individual seats rather than shared team subscriptions. Selective Rephrase requires Pro or Unlimited; choosing Lite leaves that feature behind an upgrade prompt. These distinctions keep taxes, usage allowances and feature access separate from a subscription saving.

Factors influencing the final discount value

Impact of billing cycle on promotional price

GPTinf's annual billing takes payment for the year in advance at a lower effective monthly rate. Monthly billing charges separately each month. The word allocation still refreshes with each billing month under either arrangement, and unused capacity expires at the reset. Changing a monthly subscription to annual applies the annual rate at the next renewal. Moving an annual subscription back to monthly starts after the existing annual term finishes. Paid access continues through the period already purchased. Cancellation takes effect at the end of the paid term, with subscription charges recurring until cancellation.

Promo codes vs. automatically applied offers

GPTinf's yearly saving is tied to the billing selection, with Monthly and Yearly choices above the plan cards. The free tier is a separate way to use the writing tools before purchasing, rather than a timed trial of a paid subscription. Paid plans add larger word budgets and features such as Fix All Errors. Upgrades activate immediately with a prorated word budget; downgrades begin when the current period ends. Re-humanize on Pro and above provides another form of value: revising existing text without spending more words, instead of reducing a subscription payment.

Accessing active codes for GPTinf

GPTinf's plan selection starts with the Monthly or Yearly choice above Lite, Pro and Unlimited. The cards show the subscription amount, humanizer allowance and paraphraser allowance before the Choose Lite or Choose Unlimited button. Account holders manage subscriptions through Settings and Billing; the Your Plan card shows the current plan, renewal date and payment method. For help with the offers on this page, support@gptinf.com accepts account and billing questions. A useful message identifies the account email, the action attempted and the exact on-screen message, with a screenshot showing the whole window. Scroll up for the current GPTinf offers.

GPTinf Discount FAQs

Fix All Errors prompts GPTinf free users to upgrade because applying every grammar correction together is a paid feature. The button remains visible on free and anonymous access, but clicking it opens the plan selection instead of changing the text. Paid users can paste or type into the Grammar Checker, run Check grammar and use Fix All Errors in the toolbar to apply the suggestions immediately. Individual corrections can also be accepted by clicking an underlined error. Bulk changes have no preview step and the checker does not keep a separate edit history. Reviewing the fix list before applying the corrections protects wording you intend to retain.
Yes, an existing GPTinf monthly subscription can move to annual billing at its next renewal. Billing-cycle changes are made from Settings and Billing on the existing account. Monthly-to-annual changes use the annual rate at renewal, while annual-to-monthly changes wait until the current yearly term ends. Your Plan identifies the current plan, renewal date and payment method together. Opening Account takes you directly to settings, without needing a navigation dropdown. The paid term stays active through the date labelled Renews on. That date identifies when the new billing arrangement can replace the period already purchased, keeping access attached to the subscription already in your account.
No, GPTinf annual subscriptions supply the plan's allowance month by month rather than as an upfront yearly pool. Humanizer words are counted when text is processed, and the budget refreshes at the start of each billing month. Unused words expire when that reset happens, so a yearly payment does not create a balance that accumulates across the subscription. Paid plans remove the per-run cap, but Lite and Pro still have their monthly humanizer budgets. Detector, grammar and plagiarism checks leave that humanizer balance untouched. If the allowance is exhausted, humanizing pauses until the next reset or an upgrade; upgrading provides a route to continue processing.
GPTinf uses its free tier as the trial, with no timed trial of the paid plans. You can open the Humanizer without an account and paste text or upload a PDF, Word document or plain text file. Standard and Academic modes provide different writing registers, and the rewritten output appears with a detection score underneath. A free account adds unlimited freeze keywords, which keep selected words or phrases unchanged during rewriting. Free access has usage limits, while paid subscriptions provide larger allowances and additional editing functions. Trying the free workflow with the document formats and writing mode you need helps establish which paid features matter before a subscription purchase.
Yes, GPTinf Lite includes unlimited plagiarism checks as part of its paid subscription. Pro and Unlimited include that access too, so buying a larger humanizer allowance is unnecessary solely to remove the free plagiarism cap. A registered free account has a shared allowance of 500 plagiarism words per day, and each scan spends part of it. The report retains the same matched sources, percentages and sentence-level attribution on free and paid access. The Account page's Your Plan card lists the plan allowances, including plagiarism access. For a buyer focused on originality checks, Lite provides unlimited scans without requiring the additional humanizer capacity of Pro.
Yes, GPTinf Pro includes editing functions that revise existing humanizer output without spending additional word budget. Selective Rephrase also belongs to Unlimited and works on a highlighted sentence or passage after the first Humanizer run. Clicking Selective Rephrase rewrites only the selected output, leaving surrounding sections intact and retaining the original writing mode. Re-humanize runs the whole text again without an additional word charge on Pro and above; a new run on Free or Lite consumes the applicable allowance. The selective tool replaces its previous output version. Saving a copy before revising preserves an earlier draft while the included editing function protects the remaining word allowance.
GPTinf accepts Visa, Mastercard, American Express, Discover and PayPal for subscription purchases. Sales tax is added when required, making it part of the amount payable alongside the chosen subscription. Orders with recurring charges authorize further payments until cancellation, and purchase information must remain accurate so those transactions can complete. For account holders, the Your Plan card displays the payment method and renewal date with the current subscription. Payment details can be updated through Settings and Billing if the card needs replacing. Keeping that information current helps the next subscription charge complete; cancelling the applicable subscription is the action that ends recurring payment authorization.
GPTinf reviews refund requests case by case within 3 days of the charge. Eligibility depends on the circumstances and usage, with unintentional charges, duplicate payments and technical problems among the reasons considered. Using very little of the monthly allowance supports a request, while consuming most or all of it makes approval less likely. The request goes to support@gptinf.com with the subject Refund request, the account email, the approximate charge date and a short explanation. Annual subscriptions use the same request window, and approved refunds return to the original payment method. A refund request leaves the subscription running, so separate cancellation is needed to stop future charges.
You can stop future GPTinf subscription charges by cancelling from the account's billing controls. Opening Account leads to settings, where the Your Plan card has a three-dot menu containing Cancel Subscription. The cancellation dialog shows the plan, remaining words and access end point before the Confirm cancellation action. An email confirms the cancellation, and paid features remain available until the current subscription period finishes. Account information, settings and saved work stay intact, with free access replacing the paid subscription afterward. Cancellation prevents the next billing cycle rather than returning the current payment. The completed confirmation step is what finishes the process and preserves access through the term already paid for.
GPTinf's payment processor retries a failed subscription charge before downgrading the account to free access. An expired card, insufficient balance, mismatched billing address, international transaction block or unsuccessful bank confirmation can prevent payment. The payment method can be replaced or updated through Settings and Billing, after which the automatic retry handles the charge. If every retry fails, the paid subscription falls back to free access while account data and saved history remain intact. Resubscribing is available from the same billing settings. For a bank that blocks international charges, authorizing the merchant with the bank and then updating the card gives the retry a valid payment route.
