ChatGOT vs Mammouth (2026): which should you pick?

Pick ChatGOT if

• Fits if you want chat, PDF questions and a few images from one cheap plan
• Works for light use where 10 questions a day on the free plan is enough

Look elsewhere if

• Tight if you stay free: 10 standard queries a day and nothing else
• Watch out: PDF chat, web access, custom bots and chat with images are paid only
• Skip it if you want to know the billing basis, because the pricing page doesn't state it
• Watch out: refund and cancellation terms sit in the Terms of Service, not on the pricing page
• Not for you if you want a phone app, as it's browser and extensions only

Pick Mammouth if

• Fits if you're paying for two or three AI subscriptions and would rather have one bill
• Works for people who want a second opinion, since one click sends your prompt to another model

Look elsewhere if

• Not for you if you want to try before you pay, as no free plan or trial is listed
• Skip it if you want a proper iPhone or Mac app, because it isn't in the App Store and installs from the browser
• Tight if you chat in long bursts: usage is capped per session, renews after 3 hours, then drops you to a lighter model
• Pricey if you need more room, with 3x the usage at $20 a month and 10x at $60, both billed yearly
• Watch out: dollar prices leave out VAT, and paying by bank transfer needs a yearly commitment

ChatGOT
