One model is a default, not a strategy
Paying for several AI products duplicates cost and fragments context.
Power users already switch models—they just do it across browsers, accounts, and billing relationships. A multi-model workspace removes that tax.
- 01
Subscription overlap
ChatGPT Plus, Claude Pro, and Gemini bundles add up for the same kinds of tasks.
- 02
Context does not travel
Rebuilding the same prompt in another app loses files, branches, and history.
- 03
No fair comparison
You cannot judge models fairly if setup differs every time you switch.
Unified workspace
What multi-model means in practice.
Not a model picker buried in settings—a workflow built around switching.

Ultra Mode on any chat model
Run multi-agent synthesis on GPT, Claude, Gemini, or Grok without switching apps.
Pro feature with Grok native fast path.

See divergent answers side by side.
04
Shared file context

FAQ
Multi-model questions
Which models are included?
Supported families include OpenAI, Anthropic, Google, xAI, and others available on your plan. The in-app model list is the source of truth as providers update.
Is milkyway.chat the same as Poe or other aggregators?
We focus on a disciplined workspace—math modes, branching, voice, and clear Pro/Lifetime pricing—not a bot marketplace.
Can I use my own API keys?
Lifetime plan supports bringing your own keys (e.g. via OpenRouter) for supported configurations. See pricing for details.
Does switching models share my data with all providers?
Only the model you invoke processes that message. See the Privacy Policy for provider-specific handling.
How much does milkyway.chat cost?
Pro is $14.99 per month and includes all premium models plus voice chat. Lifetime is $149.99 as a one-time payment and lets you bring your own API keys. Visit the pricing page for current plan details.
Can I try the workspace before subscribing?
Yes. You can explore the interactive math visualization example without a subscription. After signing in, you can browse the workspace interface, but sending messages requires an active Pro or Lifetime plan.
