Alter

Alter: The seamless AI that supercharges your Mac. Skip the chat, execute instant actions across all apps. 10x your productivity with complete privacy control

Alter is a Mac assistant that acts on what is already on the user's screen instead of requiring a chat window, combining screen context with voice commands so a spoken instruction can trigger a multi-step action directly inside other apps.

It reads the active app and screen content, inserts text automatically, and can control other macOS apps through voice-first workflows and dictation, with an offline option for meetings that includes speaker identification and can run on local models for privacy. It connects to more than 2,000 apps through webhooks and Shortcuts-style automation and gives access to a range of AI models rather than a single provider, which puts it in the Other AI category as a personal assistant layered directly on top of macOS instead of a separate app to switch into.

Alter can be downloaded for macOS 14 and later with no credit card required to get started, though a separate pricing page suggests paid plans exist beyond that initial download, so the exact pricing model is not fully spelled out in the material reviewed here. Mac users who want voice-driven actions across their apps can download Alter and try it without entering payment details.
