Pricing questions

You get full Premium access for 7 days. Payment details are collected upfront, but nothing is charged until the trial ends, and you can cancel at any point during it. The trial is available once per account, on your first subscription.
Yes. You can cancel from the billing portal in your account whenever you like. Your Premium features stay active until the end of the period you have already paid for, and you are not charged again after that.
Ultra AI switches AtomAI to GPT-5.6 Sol, OpenAI's deepest reasoning model, for your hardest maths, coding and research questions. Everyday questions run on GPT-5.6 Luna, which is faster. Ultra AI has its own usage limit, separate from your everyday questions, and is available on Premium. PDF uploads come out of that same Ultra allowance, so there is no separate PDF quota to keep track of.
The features are identical. Yearly works out at $5 a month, billed as $60 once a year, which saves you $36 compared with paying $8 every month.
Usage runs on two rolling windows: a short one that resets every few hours, and a weekly one. Reaching a limit pauses you until that window resets - nothing is lost and you are never charged for going over. You can see exactly where you are, as a percentage, in the profile menu inside the app. Premium raises both windows substantially.
Nothing breaks - you simply wait for the window to reset, which happens automatically, and then carry on for free. If you keep running into it, Premium gives you several times the usage across both windows plus Ultra AI, web search and image generation.
Yes. The web app and the Chrome extension are the same app and share one account, so anything you unlock applies to both, including the screenshot tool in the extension.
Payments are handled by Stripe, which accepts all major credit and debit cards. Your card details are never stored by AtomAI.
Get in touch through the contact page and we will sort it out. AtomAI is run by one person, so your message goes straight to someone who can actually fix it.
