InstaPrompt
InstaPrompt is a Chrome browser extension that provides instant AI assistance on any text selected on a web page. It overlays a small prompt button near highlighted text, allowing users to run prompts such as summarize, explain, or rewrite without copying to another tab. It also supports right-click menu commands, a keyboard shortcut (Alt+Shift+X), and a popup launcher for manual input. The tool requires no API key or initial setup; a built-in AI and starter prompt library are available immediately after installation. A free tier offers about 25 uses per month. Paid Pro features include model selection and the ability to bring your own provider key for unmetered usage. Context Labels let users save tone, brand voice, or research focus and attach them to any prompt. InstaPrompt is designed for readers and knowledge workers who frequently use AI to make sense of web content. It emphasizes privacy by design: selected text is sent to the AI to generate a response but is never stored or used for training, according to the vendor. Responses can be saved and reopened later, with prompt and library sync across devices via email sign-in.
