About Alter
Alter is a native macOS AI assistant that understands your current work context across apps, letting you talk naturally to draft emails, extract insights from YouTube videos, or turn a messy meeting into clear action items. It supports fully offline local models alongside hosted models (which are proxied without storing conversations), and voice-first workflows complete tasks roughly three times faster than typing. The core app is free — connect your own API keys or run local models, with a 7-day trial of premium models included.
