PromptHop

PromptHop is a browser extension that lets users transfer chat context from one AI tool to another in a single step. It supports multiple AI platforms like ChatGPT, Gemini, Claude, and Perplexity, preserving conversation history and reducing the need to retype context. It compresses chat data locally to save tokens and maintains privacy by keeping all data on the user's machine. The extension is available for Chrome, Edge, and Brave, with Firefox and Safari support coming soon.
