Storm2Flow Help & Features

Last updated: April 2026

Storm2Flow generates professional process diagrams from plain-text descriptions using AI. Describe your process, choose a diagram type, and get a production-ready diagram in seconds.

Getting Started

1. Sign up with your email and password, or use Microsoft SSO.
2. Create a process by clicking the + button in the process library.
3. Describe your process in the text editor using plain language.
4. Select diagram types (BPMN, Flowchart, Swimlane, Sequence, Mind Map).
5. Click Generate to create your diagrams.

That's it! You can then edit, export, share, and version your diagrams.

Diagram Types

Generate multiple diagram types from the same description. Check the types you want before clicking Generate.

Description Editor

Write your process description in the rich text editor. The editor supports markdown formatting: bold, italic, headings, and lists.

Analyse

Click Analyse to have the AI review your description for grammar, completeness, and clarity. If gaps are found, a Q&A panel appears with clarifying questions. Answer them and click Apply Answers to improve the description.

Voice Input

Click the Record button to dictate your process description. Audio is transcribed and appended to the editor. Requires microphone permission.

Image & Event Storming

Upload a photo of a whiteboard, Miro board, or hand-drawn flowchart. The AI extracts the process description and auto-generates a diagram. Also supports Event Storming board photos and DDD artifacts.

Diagram Generation

How It Works

1. Your description is sent to the AI (Claude or GPT, depending on your API keys).
2. The AI returns a structured process graph.
3. The graph is validated for structural correctness (14 checks).
4. The layout engine (ELK) positions elements with professional spacing.
5. A new version is created automatically.

Delta Generation

When you modify your description and regenerate, the AI preserves the existing diagram structure and only changes what's needed. This keeps your layout stable across iterations.

Star Rating & Learning

After generating, rate the diagram from 1 to 5 stars:

• 1-2 stars: Diagram is rejected. Next generation starts fresh (no delta).
• 1 star: Auto-regenerates immediately.
• 3-5 stars: Diagram is kept as the basis for future iterations.

Your ratings improve future generations for your organization through few-shot learning.

Viewing & Navigation

Zoom

• Ctrl + scroll wheel (or Cmd + scroll on Mac) to zoom in/out.
• Use the + / - / Reset buttons in the toolbar.

Pan

• BPMN: Click and drag the canvas background to pan.
• Arrow keys: ← → ↑ ↓ pan by 50px.
• Mermaid diagrams: Scroll normally to pan.

XML / Code View

Click XML (for BPMN) or Code (for Mermaid types) to see the raw diagram code. Click Copy to copy it to your clipboard.

Tabs

When multiple diagram types are generated, tabs appear at the top of the diagram area. Click a tab to switch between types.

Editing BPMN Diagrams

BPMN diagrams are fully editable in the browser:

1. Click Edit to enter edit mode.
2. Drag shapes to reposition them. Connections are automatically preserved.
3. Click Save to save your changes, or Cancel to discard.

If your edits change the process structure (not just layout), the AI may suggest an updated description to keep text and diagram in sync.

Version History

Every generation and manual save creates a new version. Click the version badge (e.g., "v3 - Sep 2 - You") to open version history.

• Load: Restore any previous version.
• Delete: Remove a version permanently.

Versions include the description, all diagram types, and creator information.

Export

Export your diagram in three formats:

All exports include the process name and a "struct2flow" watermark.

Sharing

Share your processes with colleagues via secure links.

1. Click the share button (↑) next to a process in the list.
2. Choose permission: Read (view only) or Write (can edit and generate).
3. Optionally set an expiration date.
4. Click Create Link — the URL is copied to your clipboard.

Recipients need a Storm2Flow account in the same organization. You can revoke a share link at any time.

API Keys & Settings

Click Keys in the header to manage your API keys.

Platform Keys vs. Own Keys

• Platform keys (default): Limited to 5 generations/day.
• Own keys: Unlimited generations, billed to your account.

Supported Providers

• Anthropic (Claude): Used for all diagram generation and analysis.
• OpenAI (GPT): Fallback for generation if no Anthropic key; also used for voice transcription.

Keys are validated with a real API call before saving. They are encrypted at rest with AWS KMS.

Delete Account

GDPR-compliant account deletion is available in the Keys modal. This permanently deletes all your processes, diagrams, share links, and account credentials.
