StealthGPT Promo Codes & Coupons February 2026

Promo codes at StealthGPT often fail due to expiration, plan incompatibility, or cached browser data. You might see errors like "invalid code" or notice no discount applies after clicking "Apply."

This commonly happens when selecting plans like Pro Annual, especially with third-party codes that have expired. StealthGPT's pricing page shows promo code fields only on subscriptions, not one-time purchases, and codes typically exclude student discounts or renewals.

To fix the issue:

1. Visit stealthgpt.ai/pricing, select your plan, and click Subscribe.
2. Enter the code in the "Promo Code" box exactly as shown (codes are case-sensitive).
3. Click Apply—the discount should show instantly if the code is valid.
4. If it doesn't work, try clearing your cache or using incognito mode.

Pro tip: Most codes are valid for 1-3 months and offer site-wide discounts of 10-25%. For best results, use codes on first purchases, especially during sales events like Black Friday.

No, StealthGPT promo codes typically apply only to first-time purchases or initial subscriptions, not renewals. This is confirmed by user reports and code terms that limit discounts to "first purchase" only.

Users often try entering codes like "STEALTH20" on renewal and see "invalid code" messages because these discounts are designed to target new sign-ups. The official policy on the pricing page verifies this limitation.

To check if a code might work on renewal:

1. Log in at stealthgpt.ai/account.
2. Go to billing during your renewal period.
3. Look for a promo field (which is often absent for renewals).
4. Contact support if needed, though they rarely honor promo codes for renewals.

Pro tip: For maximum savings, time your switch to an annual plan during promotional periods, as these often offer the best discounts (up to 33% off).

No, StealthGPT does not allow combining multiple promo codes on one order. Only one code can be applied per transaction.

If you try to use multiple codes like "UNDETECT25" and "STEALTH20" together, only the last one entered will be processed, or you'll receive an "invalid" message. This follows standard SaaS industry practice where the checkout system has a single promo code field.

Here's how to use a promo code effectively:

1. Select your plan on the pricing page.
2. Enter your best available code (e.g., 25% off annual) in the "Promo Code" field.
3. Click Apply—you won't be able to add more codes.
4. If the code doesn't work, try an alternative.

Pro tip: Choose the highest-value code available, such as 25% off an annual plan, and check the terms before attempting to use it.

No, you cannot stack promo codes with StealthGPT's student discount. The student discount is a standalone offer of $0.99 for the first month and requires a valid .edu email address.

When students sign up with their academic email, the $0.99 discount automatically applies to the first month. Attempting to add a promo code like "STEALTH20" will trigger an "invalid code" message or have no effect.

To use the student discount:

1. Sign up on the pricing page using your student email.
2. Select your plan—the student discount will automatically apply to your first month.
3. Skip the promo code box entirely.
4. Note that after the first month, you'll be charged the regular price.

Pro tip: The $0.99 student trial for the first month is often a better deal than most promotional codes for testing the service's features.

Yes, StealthGPT promo codes reliably work in incognito mode, and this approach often fixes cache-related "invalid code" errors from previous sessions.

Users report that codes like "STEALTH20" sometimes fail in regular browser sessions due to cookies but apply smoothly in incognito mode during checkout.

To use a promo code in incognito mode:

1. Open an incognito window (Ctrl+Shift+N in most browsers).
2. Navigate to stealthgpt.ai/pricing.
3. Select your plan and click Subscribe.
4. Enter your promo code and click Apply—it should verify instantly.

Pro tip: Always try incognito mode for third-party codes, as this approach has a higher success rate by bypassing tracking cookies that might interfere with new user status.

The promo code field at StealthGPT sometimes vanishes after clicking Subscribe due to browser glitches or plan pre-selection issues. This can be fixed before completing payment.

This commonly happens after selecting the Pro plan, causing users to miss out on discounts like 25% off annual subscriptions.

To solve this issue:

1. Perform a hard refresh (Ctrl+F5) on the pricing page.
2. Re-select your plan exactly as before.
3. Click Subscribe again—the promo field should reappear below.
4. Enter your code and proceed with checkout.

Pro tip: Use desktop Chrome in incognito mode to avoid mobile field bugs that have been reported in user forums.

The "invalid code" message at StealthGPT checkout usually means the code has expired, is case-sensitive, or doesn't match your selected plan (e.g., it might be for first-time purchases only).

Users sometimes type codes like "UNDETECT25" correctly but still encounter failures if the code has expired or is being used on a renewal.

To troubleshoot an invalid code message:

1. Copy and paste the code exactly (with no extra spaces).
2. Ensure you have a new account or that your plan matches the code's requirements.
3. Try using incognito mode or test another code like "STEALTH20".
4. Check for fresh, verified codes from reliable sources.

Pro tip: Most promotional codes are valid for only 1-3 months, so verify the validity dates before attempting to use them at checkout.

Yes, common StealthGPT checkout errors include "code expired," "invalid code," and situations where no discount applies after entering a code. These often occur with outdated third-party codes.

The "code expired" message typically appears for promotional codes that have reached their end date, while "invalid code" errors can happen when using codes for the wrong plans or during renewals.

To troubleshoot these errors:

1. Note the exact error message that appears after clicking Apply.
2. Verify the code's validity through its original source.
3. Try again in incognito mode to bypass potential browser issues.
4. Use verified codes like the 25% off annual plan offer.

Pro tip: If you encounter persistent errors, take a screenshot of the error message and contact StealthGPT support, as they may be able to manually apply the discount for you.
