Fluid AI

Fluid AI is a macOS application that embeds AI assistance directly into your desktop workflow, enabling you to use powerful language models inside any app. It provides a system-wide command bar and context-aware tools that work across browsers, documents, email clients, coding environments, and messaging platforms without requiring you to switch windows or copy and paste content. Users can select text anywhere and instantly summarize, rewrite, translate, or analyze it using configurable AI prompts.

For writing tasks, Fluid AI supports drafting emails, documents, and responses in-place, with options to adjust tone, length, and clarity. For research and reading, it can generate concise summaries, extract key points, and answer questions about the selected content. Developers can use it to explain code, refactor snippets, or generate implementation ideas directly in their editor.
