Jan 1.0 GA: the first offline-first desktop AI with an extension store
In one sentence Jan.ai reaches GA with version 1.0: integrated model manager, local API server, native MCP support, and an extensions system — the first desktop AI app with a plugin ecosystem. An offline alternative to ChatGPT for privacy-first users.
Jan positions itself as the answer to a simple question: why shouldn't I have a desktop AI app that works exactly like ChatGPT, but without sending any data to any external server? Jan.ai's answer is a complete desktop application that works even without an internet connection, with an experience comparable to cloud AI apps.
Jan 1.0's distinctive feature is the extensions system: like a browser with plugins, Jan allows installing community extensions that add functionality (integration with external tools, new prompt types, connections to specific services). This transformed Jan from a simple local client into an extensible platform.
Native MCP (Model Context Protocol, the Anthropic/Claude standard) support allows Jan to connect to the same tools and data sources used by Claude — calendars, file system, databases, enterprise APIs — all without cloud dependency. For those working with sensitive data, Jan 1.0 became a serious desktop alternative to ChatGPT.
