Product Builder OS · web workspace

Run the work where you learn it.

Turn today’s signal into a product decision, a skill rep, an inspectable artifact, and the next piece of evidence. The complete loop now starts—and continues—in the browser.

One connected system

Start on the web. Stay with the work.

There is no handoff to another product just to apply what you learned. Each step leaves useful state for the next visit.

  1. 01Signal

    Choose what matters

    Start with today’s brief and the decision it should change for your product.

    Open signal
  2. 02Practice

    Run the skill

    Work through a guided lab against your own context—not a generic exercise.

    Open practice
  3. 03Inspect

    Save the artifact

    Keep the attempt, output, rubric review, and revision together.

    Open inspect
  4. 04Prove

    Return with evidence

    Track the open question, challenge commitment, and proof that changes the bet.

    Open prove

Available on web now

A workspace for the work that compounds.

The web workspace is the default Product Builder OS: practical enough for a daily rep, persistent enough to show how your judgment is changing.

Enter the web workspace
  1. 01

    Projects and bets

    Keep the target user, problem, desired outcome, success signal, active bet, and threshold in one working context.

  2. 02

    Skill attempts and artifacts

    Start a practical lab, save the attempt, produce an artifact, and retain its review and revision state.

  3. 03

    Daily evidence follow-ups

    Carry an unanswered question forward until behaviour, customer, or market evidence can resolve it.

  4. 04

    Challenge commitments and proof

    Keep the customer, threshold, deadline, checkpoint work, and proof path attached to the same product.

Choose your operating depth

The browser is complete. Mac adds local execution.

Use the web workspace for the full learning and evidence loop. Add the private Mac beta only when you want agents to work against a local repository.
