Ai Helper
Ai Helper is a desktop AI companion that puts ChatGPT on macOS, Windows, and Linux. Summon it with Option+X on Mac or Alt+X on Windows and Linux, then chat, run slash prompts, or paste answers into whatever app already has focus. You connect your own OpenAI API key, so usage bills through OpenAI rather than a bundled credit pool.
Unlike browser tabs or the official ChatGPT app, Ai Helper is built for in-flow work. It offers three output modes: continuous Ai Chat, fast typewriter streaming, and paste mode that keeps code formatting intact in editors. Version 1.3 added Gemini Pro and Markdown preview, while v1.3.0 brought 30+ model engines you can switch between without leaving the overlay.
Entrepreneurs, developers, and marketers use Ai Helper to draft emails, debug code inside IDEs, and reuse custom assistant personas. The prompt library and built-in assistants let you standardize repetitive tasks, and Chinese plus English UI support makes it workable for bilingual teams.
