Gmail AutoComplete is a Chrome extension that brings AI-powered writing assistance to your Gmail. It offers multiple AI models, including GPT-3.5/4, Claude 2, LLaMA 2, and Grok 1, to help you summarize, shorten, make friendly, generate responses, complete emails, proofread, and convert text to academic or business style. With a command prompt interface and context menu integration, you can quickly improve selected text and review changes in a three-panel diff view. Your API keys are stored locally, and all processing.
