MaxAI review and alternative
MaxAI is an AI sidebar sold as a subscription. UtilEngine puts chat, inline answers and your own commands in a launcher, on your own key at provider prices.

Both answer questions about the page you are on. They differ on where the AI lives, and on who you pay for it.

Comparison based on the MaxAI site and pricing page as of November 2026. If you want AI that works the moment you install it, with image generation and no key to set up, MaxAI is built for that.
Where they differ
The first difference is who you pay for the AI. MaxAI bundles model access into its plan. The free tier includes unlimited chat on a faster model and three Pro chats a day, and Pro is $12 a member a month billed yearly, or $30 billed monthly. UtilEngine does not sell AI. You add your own OpenRouter key and pay the provider for the tokens you use, with no markup from us.
The second is setup. MaxAI works as soon as you install it. UtilEngine needs a key first, or a model server on your own computer, which takes a few minutes. In return you choose from 89 models and can give each command a different one.
The third is shape. MaxAI lives in a sidebar. UtilEngine lives in a launcher that you open and close, and the same launcher saves windows as sessions, searches tabs, and inserts snippets.
How AI commands work in UtilEngine
Select text, run a command, and the answer comes back without changing the page.
