One subscription, multiple AI models

One subscription for multiple AI models—not four monthly tabs.

Pro is $14.99/month for multi-model access with voice, math modes, branching, and Ultra Mode. Lifetime is $149.99 one-time when you prefer bring-your-own API keys. Full workspace access requires a Pro or Lifetime plan.

Workspace preview
I currently pay for three AI apps—show a week where one multi-model workspace covers the same jobs.
Any supported family

A realistic consolidation map:

  1. 01Writing and long-context on Claude-class models
  2. 02Structured reasoning on GPT-class models
  3. 03Math modes and Ultra when single-app stacks fall short

Subscription stack pain

You do not need four logos to do serious work.

Budget-conscious multi-model users hit the same wall: each provider’s paid tier is good, and the total is worse.

  1. 01

    Stacked monthly fees

    Plus + Pro + Advanced style plans add up quietly.

  2. 02

    Context tax

    Switching apps means re-explaining the project every time.

  3. 03

    Feature gaps between apps

    Math visualization, branching, and Ultra Mode rarely live in every single-provider UI.

What one plan unlocks

Models plus workspace—not only a price.

Consolidation only works if the product is complete.

Multiple families

OpenAI, Anthropic, Google, xAI, and more on supported plans.

One login.

Voice included

Voice chat on Pro and Lifetime.

Not an extra SKU.

Math modes

Strict Math and interactive visualization.

STEM ready.

Branching

Parallel solution paths without new accounts.

Power-user workflow.

Ultra Mode

Multi-agent depth on Pro for hard reviews.

When one pass is weak.

Files & search

Attachments plus live search on supported models.

Study and work.

Consolidation path

Audit, switch, cancel carefully.

Replace stacks without leaving yourself mid-project.

  1. 01

    List current AI spend

    Write down each monthly AI tool and what you use it for.

  2. 02

    Map jobs to milkyway.chat

    Confirm multi-model chat, math, files, and voice cover those jobs.

  3. 03

    Pick Pro or Lifetime

    Pro for hosted models; Lifetime if you want own keys and one-time payment.

Scenarios

Who consolidates successfully.

Student budget

I can’t keep three student AI plans active.

Pro monthly → Math + PDF → Model switch

Outcome

One predictable bill for mixed coursework.

Freelance stack

Clients need writing, research, and light code help.

Multi-model → Live search → Branch deliverables

Outcome

Fewer tools between proposal and delivery.

Key-first power user

I already buy tokens; I want one UI.

Lifetime → BYOK → Full modes

Outcome

Workspace without another pure model subscription.

FAQ

One-subscription questions

How much is Pro?

Pro is $14.99 per month and includes premium models plus voice. Cancel anytime per plan terms.

How much is Lifetime?

Lifetime is $149.99 one-time and is designed for bring-your-own API keys, with voice included.

Will one subscription replace every AI tool I use?

It replaces many multi-model chat needs. Specialized tools (IDEs, design apps, enterprise SSO products) may still be separate.

Is there a free multi-model plan?

Messaging requires Pro or Lifetime. Try the math visualization demo without a subscription.

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.
