Drop the doc in chat, get a clickable build the same afternoon. Real React, real state, the same URL your beta testers will open next week.
For product managers
Validate features before engineering writes a line
Run the prototype past real users while the spec is still up for debate.
Test it with users before it hits the roadmap
Spin up a working version of the feature in an afternoon. Hand the URL to five users, watch where they get stuck, decide whether the idea is worth a sprint. The version they tap on is real software with real state, so the feedback you get back is real too.
A shared reference everyone reads the same way
PRDs get interpreted four ways by four engineers. A clickable build doesn't. Drop the link into the spec, into Linear, into the kickoff doc. Every reviewer pokes at the same thing and disagreements become specific instead of theoretical.
Kill the idea while it's still cheap
Some features sound great in a meeting and fall apart the moment you tap through them. Better to find out now than after a six-week build. A throwaway prototype costs an afternoon. A shipped feature you have to roll back costs a quarter.
- Run the flow end-to-end before scoping it
- Spot the dead-ends in the empty state, not in production
- Walk into refinement with evidence, not a hunch
Walk into the roadmap review with proof
"I think users want this" is a slow conversation. "Here's what happened when twelve users tried it" is a short one. Show the prototype, show the recordings, show what changed after iteration two. The roadmap meeting moves on to scope instead of arguing about whether to build it.
Internal tools
Build the tools your team's been waiting for
The pages that keep sliding off the backlog. Build them in an afternoon instead of waiting for next quarter.
Decision log
Capture every product decision and the reasoning behind it, so context survives leavers and new joiners stop relitigating calls the team made last quarter.
Sprint retros
Run retros in a board the team actually keeps open — what worked, what didn't, what to try next — instead of a Notion page nobody reopens after Friday.
