ZERO ONE is your mobile command center for the TalkToAI stack.

Open four workspaces without juggling bookmarks:
• OpenZero — free AI panel
• ZeroThink — research and deeper reasoning
• ZMail — secure mail
• CallChat — voice and video when you need it

Install once. Sign in to each service as needed. HTTPS only.
Camera and microphone are requested only for CallChat.
