ZeroTwo is an AI assistant app that puts models from several companies in one place. You chat with them, hand off longer tasks, work with your files, and keep it all in one account across the web, desktop, iPhone, iPad and Android.
What you can do with it
- Chat with many models. Models come from providers such as OpenAI, Anthropic, Google and xAI. Pick one in the model picker, and switch to another whenever you like. Auto is ZeroTwo's own option that picks a fast, low-cost model for you.
- Search the web. In Chat, choose Web Search from the + menu in the message box. Answers that cite sources can show a Sources button.
- Create images and video. In Chat, choose Create image from the + menu, or open the Images page. Plans also list video generation, and it uses credits.
- Add files. Use the + button (Add files & more) in the message box and choose Files and folders, or Add from library to pick a file you already have. Your files and images are kept in your Library.
- Talk instead of type. Use Start voice conversation or Start voice dictation in the message box.
- Hand off bigger jobs. The Mode tabs at the top of the chat switch between Chat, Work and Code. In Work, ZeroTwo takes a task through several steps with tools.
- Organize your work. Use Projects for related chats, Spaces for pages and files you can share with other people, and Scheduled for tasks that run on a schedule.
- Personalize and connect. Settings > Personalization holds Memory and custom instructions. Customize lets you add Plugins, Skills and Connectors, for example Gmail, Google Calendar, Notion, Slack and GitHub.
