PM work

Clarity is the product of the process.

PMs translate ambiguity into decisions. The workspace should keep evidence and drafts together.

  1. 01

    PRD drift

    Specs rewritten in chat without the source brief.

  2. 02

    Research pile-up

    Interviews and notes never become a decision.

  3. 03

    Unchallenged roadmap

    Priorities feel obvious until launch week.

PM toolkit

Discovery to decision.

Writing, synthesis, and critique.

Briefs & research

Attach notes, surveys, and PRD drafts.

One thread.

Write then challenge

Draft with one model; critique with another.

Better specs.

Option branches

Keep P0/P1 cuts as explicit forks.

Visible trade-offs.

Live market scan

Current competitor and category context.

Supported models.

Deep prioritization

Raise effort for scoring frameworks.

When it’s messy.

Ultra Mode

Multi-agent product review on Pro.

Before commit.

PM loop

Frame, evidence, decide.

A lightweight product decision path.

  1. 01

    Frame the problem

    Users, constraints, success metrics.

  2. 02

    Synthesize evidence

    Attach research and extract decision-relevant facts.

  3. 03

    Challenge the plan

    Second model or Ultra Mode on risks and scope.

PM scenarios

Product jobs across discovery and delivery.

PRD draft

Turn these notes into a PRD with open questions.

Attach notes → Writing model → Branch scope

Outcome

PRD with explicit unknowns.

Prioritization

Score these initiatives with RICE and risks.

Reasoning → Branch cuts → Second model

Outcome

Transparent ranking.

Launch risks

What will break this launch plan?

Ultra Mode → Files → Live search

Outcome

Risk register draft.

FAQ

PM questions

Does this replace product analytics tools?

No. Use it to reason on top of data you bring in as text or files.

Can engineering use the same threads?

You can share exports or copy outcomes; the product is an individual multi-model workspace.

Is Ultra Mode useful for PRDs?

Yes for high-stakes specs—parallel critique before you lock scope.

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.
