The problem

Writing specs shouldn't be the job.

Every PM knows the pain. You have a clear vision in your head, but turning it into a properly structured story with sharp AC, the right format, and a defensible priority score takes forever.

01

Inconsistent quality across your team — every PM writes stories differently, engineers interpret them differently, and QA tests them differently.

02

AC is an afterthought. Most user stories have success metrics where acceptance criteria should be — and nobody catches it until the sprint review.

03

Prioritization is gut feel dressed up as a framework. You know the formula, but applying it consistently to every story across a full roadmap takes hours.

04

Format tax is real. Jira, Linear, Notion, Confluence — every tool has a different structure, and you're the one reformatting everything by hand.

How it works

Four inputs. One complete story.

Describe your user and goal

Tell Kantan who the user is, what they want to do, and why it matters. No templates, no rigid forms — just a natural description.

→

Set your context

Platform, team size, effort level, and which metrics matter. Kantan uses this to calibrate the AC and prioritization score to your actual situation.

→

Define how you'll measure it

Select your metric type, cohort window, analytics platform, and guardrail. Kantan generates the full measurement plan — no freeform, no ambiguity.

→

Get a complete story

User story, definition-of-done AC, RICE priority score, measurement plan with event names, a shareable measurement blueprint, and export-ready output for Jira, Linear, or Notion.
