Stop starting over.
Meet Wim.

Wim remembers what you built, understands what changed, and tells you what to build next—across every AI builder.

Wim by StackSwap

Start with free Discovery.

Create a private project and show Wim what already exists. Discovery stays free until Wim understands enough to guide the next build.

Start your first project

Your project stays private to your account.

Builder → Wim → Builder.

Keep the AI builder you already use. Wim carries the project history between builds and gives you the next focused move.

  1. 01Project

    Start with free Discovery

    Give Wim the project context and bring back your builder’s responses.

  2. 02Memory

    Project Memory grows

    Each response helps Wim remember what works, what changed, and what is still unknown.

  3. 03Graduation

    Continuous QA begins

    Once Wim understands enough, he starts prioritizing the next highest-impact work toward launch.

One memory that grows with every build.

Every accepted builder response adds to what Wim remembers: what changed, what is settled, and what still needs to be checked.

Project memoryBuilt from your project evidence
  1. DiscoveryEstablish

    Show Wim what already exists.

    Your goal, important decisions, what works, and what is still unknown are remembered together.

  2. GraduationUnlock

    Wim understands enough to guide the project.

    When Wim has enough reliable information, free Discovery ends and the project graduates to Continuous QA.

  3. Continuous QAAdvance

    Get the next build move.

    Wim reviews new work against everything already learned and gives your builder the next focused prompt.

More history. Less re-explaining.

Your next build prompt starts from the project’s history—not from zero.

Your builder builds.
Wim checks the work.

AI builders are designed to keep moving. Wim steps back, checks what is actually true, and finds the problem worth fixing next.

That independent second look keeps more work from piling onto a weak foundation.

AI builder

Moves the build forward.

  • Builds what you ask for
  • Ships the next change
  • Keeps the project moving
Wim

Checks the work independently.

  • Checks assumptions against the project
  • Protects what already works
  • Chooses what matters most next

One loop. A smarter next move.

Wim turns each completed build into better project memory and one clear next work order.

Builder promptDo the work

Implement checkout without changing the existing account flow. Test successful and failed payments.

One focused prompt goes to the AI builder you already use.

Execution receiptShow what changed

Checkout and subscriptions are working. Successful and failed payment paths were tested.

Your builder returns the result and the proof behind it.

Updated Project MemoryRemember

Payments work. Refunds, duplicate events, and recovery still need proof.

Wim remembers the progress and carries the open questions forward.

Next work orderMove forward

Verify refunds, duplicate webhook events, and payment recovery without changing checkout.

The next highest-impact move is ready for your builder.

Give your project a memory.

Discovery is free until Wim understands enough to guide what comes next.
