BrainyAI is a sidebar tool that brings AI chat, search and summarization abilities to your browser. It offers a direct interface to the large language models like GPT-3.5 and GPT-4, so you can chat with multiple models at once and compare their results. The tool can read documents, web pages and even generate AI-powered copywriting within the writing interface.
Another option is Voilà, an AI browser assistant that works alongside whatever browser you're using. Voilà offers tools for content creation, writing, brainstorming and research. It supports GPT-4 and offers a shared workflow system for teams, with data stored locally and not used to train AI models.
