FAQ

How does the monthly chat quota system function for different user plans?

Each plan includes a specific monthly chat quota that resets at the start of the billing period. Free plan users receive two chats per month, while Solo users receive twenty chats per month. These quotas reset automatically on the billing renewal date and do not roll over (verified: 2026-01-30).

What options are available to users who reach their monthly AI chat limit?

When a user reaches their monthly limit, they can either upgrade to a higher plan for more chats or provide their own API keys from providers like OpenAI or Anthropic. Using personal API keys allows for unlimited chats within the AutEng interface (verified: 2026-01-30).

What specific types of technical formatting does the AutEng editor support?

The editor is designed for technical documentation and supports Markdown for structure, Mermaid for diagrams such as sequence or architecture charts, and KaTeX for mathematical notation. It also includes features for code examples and web-based research integration (verified: 2026-01-30).
