About AutEng
What is AutEng?
AutEng is an AI-native workspace designed for creating technical documentation. It combines Markdown, Mermaid diagrams, and KaTeX math support in one editor, with an AI assistant that helps you structure content, generate code examples, and research information. You can test the editor without an account on the homepage.
What problem does it solve?
Technical teams often juggle multiple tools for writing, diagramming, and math notation, leading to fragmented documentation. AutEng centralizes these capabilities in one place, while the AI assistant speeds up drafting and ensures consistency. For software engineers, mathematicians, and data scientists, it simplifies producing architecture docs, API references, and algorithm explanations.
Who is it for?
AutEng is ideal for individual developers, technical writers, and small teams who need to create and share professional documentation. It is not for teams requiring advanced collaborative features (like shared projects) yet, as those are on the roadmap. The free plan offers limited AI chats, but you can bring your own API keys for unlimited use.
Real use cases
Use AutEng to create system architecture diagrams with Mermaid, embed LaTeX equations for machine learning papers, or generate API reference docs with syntax-highlighted code blocks. Its web research capability helps keep docs current.
Key features
- Markdown & AI writing — Draft structured technical documents with AI assistance.
- Mermaid diagrams — Create architecture, flowcharts, and sequence diagrams visually.
- KaTeX math — Write LaTeX equations for algorithms and proofs.
- Code highlighting — Include syntax-highlighted examples in Python, TypeScript, and more.
- Web research — The AI can fetch current information to ensure accuracy.
- No-account editor — Try the editor immediately without signing up.
