Visual PRD

A visual PRD is
a plan you can move.

A product spec drawn as boards: every page, its words and its data. This is Kestrel’s, a crypto wallet, on one canvas.

Three days free.
Kestrel as a visual PRD: Home, Portfolio, Swap and Earn in order, a data board, and two notes on the canvas
Every page
In the order a user meets them
Real words

Open questions
As notes, on the page

Five lines that read as finished. Five decisions still open.

Adam’s written spec looks done. Each line leaves a decision to whoever builds it. The board made all five.

kestrel-spec.mdread only, nothing here moves
  • Users can swap between tokens.

    Left open: Which pair, and what do they see before they confirm?
  • Show transaction fees.

    Left open: In gwei, or in dollars?
  • Handle slippage.

    Left open: What does a first-time buyer read?
  • Users can earn rewards.

    Left open: As APY, or as money?
  • Show the balance.

    Left open: One total, or per coin?

  • “Change ETH to USDC”, You pay, You get about
  • “Fee: $3.10, paid to the network”
  • “The price can move by up to 0.5% before it goes through”
  • “4.1% a year”, and what it made, in dollars
  • The total, then every coin under it

Every PRD section has a place on the canvas.

Most are easier to check there, on the page they describe.

How to make one.

Six moves, from one sentence to boards you would build from.

  • Write one sentence

    What it is, and who it is for.

  • List the boards in order

    Every page a user meets, first to last.

  • Put real words on each

    A grey bar is a decision nobody made.

  • Draw the unhappy states

    The empty week. The declined card.

  • Draw the data

    The tables each board needs, as a board.

  • Move it until it is right

    Then build exactly those boards.

AI builds better from boards than from words.

A paragraph gets pictured by the builder. A board already was, by you. Then Devi builds exactly that.

  • The board
    The Kestrel portfolio page as a board
  • The design
    The same portfolio page, designed
  • The build
    The live build window: Kestrel’s portfolio page online at its own address

Everyone reads the same plan.

Share the link. Your team, a client or an investor comments on the exact board, with no account, and the AI employees make the change.

A comment thread on the Kestrel design: the reviewer asks, Anouk changes only the balance, the reviewer agrees

Visual PRD: common questions.

What is a visual PRD?

A product spec drawn as boards: every page, its words and its data.

How is it different from a wireframe?

A wireframe is one page. A visual PRD is every page, linked, decided.

Does it replace the written PRD?

For what gets built, yes. Pin the goal to the first board.

Is there a template?

Start from the ten boards most products need, listed above. Cut what yours does not have.

Why does AI build better from one?

A paragraph leaves gaps the builder fills its own way. A board leaves none.

Do I need design skills?

No. Type a sentence. Nadia draws the boards.

Type one sentence. Get the boards back.
