AI User Story Generator: Prompts, Templates & Examples

In my experience, user stories are the working unit of agile teams - and bad stories cause bad sprints. Good stories take time to write well, which is why I see teams chronically underinvest in them. AI changes the math for me: a high-quality user story now takes 5-10 minutes instead of 30-45 minutes, and the team can iterate fast.

In this guide I share the prompts, templates, and review patterns I’ve found make AI user story generation reliable, plus the failure modes I’ve watched catch teams off-guard. Use it as the working manual I wish I’d had earlier.

A great user story has:

• A user: who needs this.
• A goal: what they want to accomplish.
• A reason: why it matters.
• Acceptance criteria: how we know it is done.
• Dependencies: what else must be in place.
• A reasonable size: small enough to ship in one sprint.

Skip any of these and the story underperforms.

A working workflow:

• PM/PO drafts a one-line problem statement.
• AI generates a draft story with AC.
• Human reviews against INVEST and context.
• Team refines in sprint planning.
• Final story in PM tool.

End-to-end: 10-15 minutes per story instead of 30-45.

Prompt 1: Generate a story from a problem statement

“You are a senior product owner. Below is a problem statement. Generate a user story in the format: ‘As a [user] I want [goal] so that [reason]’. Include 6-10 acceptance criteria covering happy path, edge cases, error states, and DoD. Output as markdown.”

Prompt 2: Refine an existing story

“Take this story and improve it: [paste]. Score it against INVEST. For any criterion failed, propose a specific fix.”

Prompt 3: Generate acceptance criteria only

“Take this story: [paste]. Generate 8-12 acceptance criteria. Use Given/When/Then format. Cover happy path, edge cases, error states, observability, and DoD.”

Prompt 4: Split a story

“This story is too big: [paste]. Suggest 3 ways to split it that each deliver independent customer value. For each split, name the new stories and what gets deferred.”

Prompt 5: Convert a feature description to stories

“Below is a feature description from a roadmap. Decompose it into 5-10 user stories. For each: title, narrative, AC. Order by suggested priority.”

INVEST = Independent, Negotiable, Valuable, Estimable, Small, Testable.

A useful audit prompt:

“Run INVEST checks on this story: [paste]. For each criterion, state pass or fail and why. Propose specific changes for any failed criterion.”

Output is a 6-line audit. Address the failures and re-run.

AI-generated AC tends toward generic. Improve with these techniques:

• Specify the format: “Use Given/When/Then” or “Use checklist format”.
• Demand coverage: “Include error states, edge cases, observability”.
• Demand specificity: “Each AC must reference a specific user behaviour or system state”.
• Demand testability: “Each AC must be objectively testable”.

A working AC generation prompt:

“Generate 8-12 acceptance criteria for this story: [paste]. Use Given/When/Then. Each AC must be objectively testable, reference a specific user behaviour or system state, and avoid vague language. Cover happy path, 3 edge cases, 2 error states, observability hooks, and DoD.”

Common splitting patterns AI applies well:

• SPIDR: Spike, Path, Interface, Data, Rules.
• Workflow steps: each step a story.
• Business rules: each rule a story.
• Happy path / edge cases: ship happy path first.
• Configurations: one config first.

A useful prompt:

“This story is too big: [paste]. Apply 3 different splitting strategies. For each, output the resulting stories. Recommend the best split for delivering customer value fastest.”

A higher-leverage workflow: generate stories directly from user research.

“Below are 8 user interview transcripts. Identify pain points worth solving. For the top 5 pain points, generate user stories with AC. Include a count of how many users mentioned each pain.”

This converts research into actionable backlog in minutes. Pairs especially well with continuous discovery practices.

Before any AI-generated story enters the backlog:

• Does the story have a real user, not a generic “user”?
• Is the goal specific to a behaviour, not vague?
• Is the reason (“so that”) concrete?
• Do the AC cover error states and edge cases?
• Is the size reasonable for one sprint?
• Are dependencies named?
• Is it testable?

A 60-second review pass per story prevents bad stories from entering planning.

• AI invents users. Always specify the real user from your discovery.
• AC drift to generic. Demand specificity in the prompt.
• Stories that look good but lack scope clarity. Add “What is explicitly out of scope?” as a section.
• AI assumes UI conventions you do not have. Provide your design system context.
• Over-specified AC. Trim to the essential. Engineers can add their own internal criteria.
• Identical-sounding stories. AI templated outputs. Edit for voice.
• Missed business context. AI can’t know your strategic priorities. Inject them in the prompt.

Story template:

As a [specific user] I want to [specific goal] So that [concrete benefit]

Acceptance criteria: - Given X, When Y, Then Z - (more)

Out of scope: - …

Dependencies: - …

Refinement template:

Story title Narrative (As a… I want… So that…) Background context AC Design link Dependencies DoD additions specific to this story

Consumer software: focus on user emotions and journey moments. AC includes UX states.

B2B SaaS: focus on workflow integration and admin / end-user separation. AC includes role-based behaviour.

Mobile: AC includes platform-specific (iOS/Android) considerations, offline state, push notifications.

Hardware: AC includes physical states, calibration, error recovery.

Internal tools: simpler narratives, focus on process compliance and audit logging.

Marketing/ops: stories about tasks rather than user experiences. AC includes deliverables and approval flows.

For teams to benefit:

• Save prompts in shared Notion or Confluence.
• Tag each prompt with use case.
• Note expected output format.
• Include examples of strong prompt outputs.
• Update quarterly as models change.

A team-wide prompt library is one of the highest-leverage investments a scrum master or PO can make.

Track:

• Refinement edits per story: declining is good (prompts improving).
• In-sprint scope changes: declining is good (stories were sized correctly).
• Stories carried over: declining is good (better estimation).
• Engineer satisfaction with stories: pulse survey, should rise.
• PO review time per story: should drop after prompt library matures.

If quality drops, the issue is usually prompt drift, not AI itself.
