IntelliBar

As a Mac AI assistant, IntelliBar differs from most by putting several AI models behind one interface and charging a one-time price for the app instead of a subscription.

IntelliBar is an AI writing assistant for macOS that helps with writing, editing and email-style tasks, and its prompt completions cut down on retyping.

There is a catch on cost.

IntelliBar relies on external AI provider APIs, so you bring your own access and pay those providers for what you use.

The app purchase does not cover model usage.

If privacy matters to you, IntelliBar also supports local models, which can keep sensitive drafts on your own machine.

Local models are usually smaller than the hosted ones, so expect a tradeoff there.

IntelliBar runs only on Mac, so Windows and Linux users are left out.
