Chatbot App vs Mammouth (2026): which should you pick?

Pick Chatbot App if

• Fits if you want many models and image tools under one membership
• Works for people willing to pay monthly to get past the free plan

Look elsewhere if

• Pricey if you pay monthly: Pro is $29.99, and only the monthly price could be read
• Tight if you stay free: limited messages on one model, no files, images or voice
• Not for you if you might want your money back, as refunds need under 20 messages sent and a request within 3 days
• Watch out: the trial is $1.99 for a week, then $29.99 a month
• Watch out: the maker, HubX, says it is not affiliated with the model providers

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

Chatbot App

• The free plan has limited messages and no file upload, image generation or voice mode.
• Its refund policy allows a refund only if fewer than 20 messages were sent and the request comes within 3 days of first purchase.
• The pricing page shows monthly, quarterly and 6-month selectors, but only the monthly price could be read from the page text.
• Chatbot App says it is not affiliated with OpenAI, Google or the other model providers and uses their official APIs.

Mammouth

• There is no free plan, and the pricing page lists no free trial.
• Usage is limited per session and quotas renew after 3 hours. At a model's limit Mammouth switches to a lighter model.
• There is no App Store app: on iPhone, Mac and Windows it installs from the browser as a web app. Android has a Play Store listing.
• Prices are shown in euros or US dollars depending on the visitor's country, and dollar prices exclude VAT. Paying by bank transfer needs an annual commitment.
