Architecture Diagram Templates: Auto-Generate from Plain Text

Professional architecture diagram templates with AI generation. Create system diagrams, sequence diagrams, ER diagrams, and flowcharts automatically from Slack discussions or plain text descriptions using Mermaid.

Creating Diagrams in draw.io Takes Hours

Engineering teams spend 2-3 hours creating system diagrams in draw.io, Lucidchart, or Figma. Diagrams quickly become outdated and version control is a nightmare. resetDocs auto-generates Mermaid diagrams from your technical discussions—version controllable, editable as code, and always in sync with docs.

Diagram Examples

User authentication sequence diagram example
User Authentication Flow
Sequence diagram showing OAuth 2.0 authentication with PKCE flow between client, API, and auth provider.
Microservices architecture diagram example
Microservices Architecture
System diagram showing API gateway, service mesh, databases, message queues, and external integrations.
Database ER diagram example
Database ER Diagram
Entity-relationship diagram with tables, foreign keys, one-to-many and many-to-many relationships.
Payment processing sequence diagram
Payment Processing Flow
Sequence diagram showing payment gateway integration, webhooks, and database state changes.

How Automatic Diagram Generation Works

1. Describe Your System in Slack

Discuss your architecture, API flows, or database schema in Slack. Include component names, data flows, and relationships.

2. AI Generates Mermaid Diagrams

Tag @resetDocs and our AI automatically creates Mermaid diagrams embedded in your technical spec or design doc.

3. Edit & Version Control

Diagrams are stored as Mermaid code—edit them inline, commit to Git, and render in GitHub, Notion, or Confluence.

Why Use Mermaid Diagrams?

Version Control Friendly
Diagrams are plain text—commit to Git, review in PRs, and track changes over time.
No External Tools
No draw.io, Lucidchart, or Figma subscription needed. Edit diagrams as code in your IDE.
Always Up to Date
Diagrams live in the same doc as your spec—no broken links or outdated screenshots.
Universal Rendering
Mermaid renders in GitHub README, Notion, Confluence, GitLab, and most modern doc platforms.
