Antispace

Antispace describes itself as an artificially intelligent operating system: a single workspace where an AI agent connects to a user's email, calendar, notes and to do lists and carries out actions across them. Users chat with the agent about their workspace, ask it to draft replies, schedule events or search, and receive a daily brief built from the connected tools. It is aimed at individuals who want an AI assistant that acts rather than only answers. Listed features include a built in mail client with semantic search over the inbox, a calendar, support for multiple email and calendar accounts, memory the user can shape with plain instructions such as asking it to remember a preference, and brainstorm mode. Users can install AI characters with distinct personalities and pick between models from Anthropic, Meta, OpenAI and Perplexity from chat. The vendor states that user data is not used to train third party model providers or for advertising, and that it holds CASA Tier 2 certification. The site says Antispace is completely free for now and publishes no paid plan prices. Sign up is available on the home page.
