Alter

What It Does

Alter is a native macOS AI assistant that transforms how Mac users interact with their computers through voice-first workflows and deep system integration. Unlike traditional AI chatbots, Alter understands your current screen context, controls native macOS apps, and executes complex multi-step actions through natural voice commands—all while maintaining privacy with optional offline/local model support.

Who It's For & Key Problems Solved

Designed for Mac power users, professionals, and teams who want to escape the limitations of web-based AI tools. Alter solves the friction of constantly switching between apps, copy-pasting AI responses, and losing context across workflows. It's built for users who value speed, privacy, and seamless integration over siloed AI experiences.

Key Features & Capabilities

• Screen Context Awareness: Understands what's on your screen across all macOS apps, providing contextual AI assistance without manual input • Voice-First Workflows: Complete tasks 3× faster through natural speech-to-action commands with automatic insertion into any app • Native macOS Control: Direct integration with iMessage, Calendar, Maps, Notes, Keynote, and other native apps • Meeting Intelligence: Records and transcribes meetings from any platform (Zoom, Google Meet, in-person) with speaker identification and AI-powered summaries • 50+ AI Models: Access to the latest models from OpenAI, Anthropic, Google, Meta, and more—automatically routed for optimal performance • Privacy-First Architecture: Works offline with Ollama and LM Studio for local processing; encrypted chats that never train on your data • Universal App Integration: Built-in actions for 2,000+ services via webhooks, Shortcuts, and direct integrations • 2-3× Faster Responses: Optimized routing delivers AI answers significantly faster than ChatGPT or Claude

Typical Workflows

Alter excels at seamless productivity enhancement: dictate messages that auto-insert into Slack, extract insights from documentation while browsing, generate Keynote presentations from PDFs, control Calendar and Notes via voice, chat with meeting transcripts for instant insights, and create custom automations across your entire app ecosystem. The AI automatically selects the best model for each task—Claude for writing, Gemini for web search, GPT-4o for complex reasoning.

What Sets It Apart

Alter is the only Mac AI assistant combining full screen context awareness, native app control, voice-first interaction, offline capability, and meeting intelligence in a single package. It lives in your menu bar, launches on startup, and feels like a natural extension of macOS itself—bridging the gap between what Apple Intelligence should have been and what power users actually need.
