Alter
Overview
Alter is a native macOS AI assistant that seamlessly integrates with every app on your Mac, offering context-aware help across your entire workflow. Unlike standalone chat interfaces, Alter understands what you're working on and provides intelligent assistance without breaking your focus. From drafting emails to summarizing meetings, this productivity tool transforms how Mac users interact with AI throughout their workday.
What distinguishes Alter from other AI assistants is its deep system integration. The app taps directly into your applications and browsers, allowing you to perform tasks instantly without switching contexts. Whether you're working in Safari, writing in Pages, or reviewing documents in Finder, Alter provides relevant assistance based on what's currently on your screen. This context-awareness makes it feel less like a separate tool and more like an extension of macOS itself.

Privacy-conscious users will appreciate Alter's security-first approach. All conversations are encrypted locally, and the platform supports completely offline operation through integration with Ollama and LM Studio. You maintain full control over your data, with options to use your own API keys or run AI models entirely on your device. The app never stores your data for model training, addressing common concerns about AI privacy.
The voice-first interface sets Alter apart in the crowded AI assistant market. Instead of typing commands, you can speak naturally to dictate messages, emails, and documents across any application. Users report completing tasks three times faster using voice commands, particularly for routine writing and communication tasks. The meeting recording feature works with both online platforms, such as Zoom, and in-person discussions, automatically generating summaries and action items.
