Launching todayAI Sidebar for GPT, Claude & Gemini
Thinkbeside is a Chrome extension that places AI models in a sidebar beside the page, PDF or video you are viewing. It is aimed at people who want to question their reading without copying text or switching tabs. Users connect their own API keys from OpenAI, Anthropic, Google, DeepSeek or xAI and pick the model they want. The extension itself is free to install, and users pay each AI provider directly for what they use.
