Why people choose zy.ai
ChatGPT is one lab. Claude is one lab. Gemini is one lab. zy.ai is many labs plus free models - in one chat, with the same history when you switch.
Most people who try AI open a single brand app. That works until the next task needs a different strength - careful code, a second opinion, a free model for volume, or Grok-style iteration. Then they open another tab, re-paste the thread, and lose the plot.
zy.ai was built for that moment. One workspace. Many models. Same conversation.
