What is Krater?
Krater is a web-based AI workspace that bundles ChatGPT, Claude, Gemini, Grok and more than 400 other AI models under a single subscription. Users can chat with any model, switch models mid-conversation, or let an Auto Router pick the model for them. The workspace also includes creative tools for making and editing images and videos, building slides, websites and live-preview artifacts, generating code, and working with text-to-speech, sound effects and transcription.
Beyond chat, Krater offers an agent that takes a goal, plans it, researches on the web and runs tools to deliver a finished result. It can connect to over 1,400 apps such as Gmail, Slack, Notion and GitHub, run scheduled tasks, and keep memory and projects so it retains context and files. Users can also upload PDFs, URLs or videos to get summaries and answers from their own sources.
