zy.ai
One chat. Many labs. Same history.
ChatGPT is OpenAI only. Claude.ai is Anthropic only. Gemini's app is Google only. zy.ai is the workspace in between: create a free account (no card), use quality free models, or unlock Claude, GPT, Gemini, and Grok on Pro — without re-pasting the brief.
How zy.ai compares
Not a rank list. A product shape. Pick the surface that matches how you actually work.
ChatGPT / Claude / Gemini apps
Best when one vendor already covers 95% of your week. Weak when you keep opening a second tab and pasting the same context.
Poe-style aggregators
Many named bots, often a new thread per bot. Fine for play. Harder when the job is one long piece of work.
Perplexity-style answers
Built to cite the live web. Use that when the job is sourced research. zy.ai is chat-first: models, history, then optional search and Ultra agents.
Multi-model workspace
One conversation. Free models to start. Frontier labs on Pro. Voice and research agents on Ultra. History stays when you switch.
When zy.ai is the better tool
You already bounce between labs
Draft on a free model, then want Claude for the hard pass, then GPT for a second cut. Same thread.
You refuse a card to try
Five honest guest messages. Sign in only if you want to keep the work.
You want one bill you can explain
Free, Pro $15, Ultra $45. Not three lab subscriptions plus a fourth search app.
When to stay on a single lab
If one family already does almost every task, and your team trained there, stay. Multi-model wins when tasks diverge every week. More: single lab vs multi-model.
Start in one minute
Ask a real job
An email, a function, a rewrite. If it helps, sign in so the thread is saved.
Upgrade only if needed
Pro when frontier quality is weekly. Ultra for Voice and research agents.
Is zy.ai a ChatGPT clone?
No. ChatGPT is OpenAI's product. zy.ai is a multi-model workspace that can include GPT models on Pro, plus other labs, plus a real free tier.
Do I need Pro to use Claude or GPT?
Yes. Free stays on free models. Pro ($15/mo) unlocks frontier labs in the same chat.
Is this a Perplexity alternative?
Only if you wanted one place to chat across models. Perplexity is search-first with citations. zy.ai is chat-first; Ultra adds research agents when that is weekly work. See Perplexity alternative.
