You can paste your website on aiter.io and get a real Marketing Brief before making an account. That is on purpose. The honest way to judge the output is to see it written about your own business, not about a demo company.
There are limits, and they are worth knowing before the first click.

What 5 credits cover
A visitor gets 5 credits, once. There is no daily top-up and no monthly refill, and the count is kept per network rather than per browser, so clearing cookies does not bring it back.
A campaign built from one website costs 1 credit. The first set of Google Ads is written automatically when the brief lands, at no extra charge. That leaves four credits for Meta ads, social post ideas or another round of headlines, which is plenty to tell whether the writing sounds like your business.
One campaign per visitor. Starting a second one asks you to sign up.
Which pages open
Four pages work without an account: Marketing Brief, Google and Meta under Ads, and the ideas list in Socials.
Everything else in the sidebar opens to a short note on what it does, with a sign-up button. That covers the four research reports, LinkedIn and TikTok ads, the Video Studio, articles, email, YouTube, PR, SEO, strategy, and turning social ideas into finished posts.
Why pictures need an account
Banners and social images ask for a login on every plan, the free one included. A picture takes far longer to make than a paragraph and costs 5 credits, so it waits for an account. Text stays free to try.
What happens when you sign up
The campaign comes with you. Sign up in the same browser and everything you generated moves into the new account, whichever sign-in method you pick, so nothing has to be rebuilt.
A new free account then starts with 10 credits, once. It also earns the streak bonus: spend a credit on seven days in a row and 5 bonus credits arrive. Paid plans add a monthly allowance and open the rest of the product, and which plan you need lays them side by side.
Frequently asked questions
Do the 5 credits reset?
No. They are a one-time allowance for trying the product. An account is the way to keep going.
Why did I hit a sign-up wall with credits left?
The wall is about the page, not the balance. Research, pictures, video and the other locked sections need an account whatever you have left.
Will my campaign survive if I sign up with Google?
Yes, as long as you sign up in the browser you used to make it. The sign-in method does not matter.
