How to use Claude, GPT, and Gemini together in one chat
You do not need three browsers. You need a switch rule — when each model enters the same thread.
Want to use Claude, GPT, and Gemini together without copy-paste chaos? On zy.ai Pro/Ultra you open one chat, keep one history, and switch models when the job changes. Free plans stay on free models first.
Step-by-step workflow
- Start on a free model for outline or sketch (Free tier).
- When quality stalls, switch to Claude for careful code/long structure.
- Use GPT when you want a generalist second pass.
- Try Gemini for research-shaped or multimodal-heavy turns.
- Keep the same thread — never re-explain the project in a new lab login.
Deeper comparison: Claude vs GPT vs Gemini.
Switch rules that work
- Plan → free — brainstorm and outline cheaply
- Hard code → Claude-style depth when available on Pro+
- General polish → GPT when you need a different cut
- Research synthesis → Gemini when that strength fits
- Stuck twice → change model, not the whole tool
Multi-model is a method. Random model spam is not.
One subscription framing: one subscription many AI models.
Plans required
- Free — free models only
- Pro $15/mo — frontier models including Claude/GPT/Gemini/Grok as listed
- Ultra $45/mo — capacity, Voice, agents, Deep Research
Upgrade timing: Free vs Pro. Free online overview: free AI chat online.
Optional tools mid-chat
Connect MCP servers (GitHub, Notion, …) on member plans so models act on your stack — MCP tools in AI chat. Docs: /docs.
Run the multi-model workflow
Start free on zy.ai, then unlock frontier models on Pro when the work earns it.
