Alter Reviews

Reviewers consistently describe Alter as a Mac AI assistant they use every day because it stays close to their workflow: it understands on-screen context, works across apps, and makes common tasks like replying to email, summarizing meetings, and organizing prompts faster with less window-switching. They also repeatedly praise its broad model access, speed, low resource use, customizable actions, and privacy options, including local or no-retention models. The only notable complaint is that chat history and the chat interface still feel rough, though users say the team ships updates quickly and listens closely.
