Five things on one board.
A paragraph misses all five.
The first board of the flow, marked.
Book a slot
ConfirmOpen on Thursday
A patient picks a slot before they make an account, never after.
- 1
Its place
Titled above the frame, where a user meets it in the flow.
- 2
The real words
The button says Confirm. What is written here ships.
- 3
Its states
Open, open, taken. The taken slot looks different.
- 4
Its data
Each field here is a column on the data board.
- 5
The decision
Slot first, account after, written on the page it changes.
Every PRD section
has a place on the canvas.
Most are easier to check there, on the page they describe.
| Section | In a written PRD | In a visual PRD |
|---|---|---|
| Problem and goal | A paragraph at the top | A note on the first board |
| User stories | “As a patient, I want…” | The boards, in order |
| Requirements | Numbered lines | Fields and buttons on each board |
| User flow | A diagram elsewhere | Arrows between the boards |
| Edge cases | A list, if remembered | Boards of their own |
| Copy | Placeholders | The real words |
| Data model | A separate document | A data board |
| Open questions | A section at the end | A sticky note on the board |
Five lines that read as finished.
Five decisions still open.
Each leaves a decision to whoever builds it. The boards above made all five.

How to make one,
in six steps.
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.
On HuntingHydra you write step one. The team drafts the rest with you. How it works.
The boards
most products need.
Start here. Cut what you do not need.
The first page
What it is, and the next step.
The core action
The page the product exists for.
Sign up
Where you ask, and why there.
Confirmation
What just happened.
The empty state
The first visit, or a quiet week.
The costly error
The declined card, the double booking.
The dashboard
Where a returning user lands.
The message back
The reminder, the receipt.
Settings and billing
The plan, and the way out.
The data
The tables behind all of it.
AI builds better
from boards than from words.
Nothing to picture
A paragraph gets pictured by the builder. A board already was, by you.
Changes stay cheap
On a board, a change is a retyped line. After the build, it is a rebuild.
What you approved ships
Devi builds straight from the boards you moved.
The HuntingHydra studio learned this on client work. The product is that finding.
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.
