AI English speaking coach with instant pronunciation feedback
Speak out loud and receive real-time scoring on pronunciation, fluency, and intonation with specific corrections.
Lessons adapt to your current level, goals, target accent, and industry focus.
Practise interviews, meetings, presentations, and casual conversation with interactive AI avatars.
Beginners can start conversations in their native language to ease the transition into English.
AI diagrams and technical design docs built from your code and systems
Generate architecture diagrams, flowcharts, sequence diagrams, and BPMN from a text prompt, code, Terraform, or an uploaded PDF, Word, Excel, PowerPoint, Draw.io, or Visio file.
Build interactive maps that sync with cloud accounts, repositories, and internal catalogs so the picture stays close to the real environment, with drill-down from org level to a single container.
Paste code or connect private and public Git repositories, Confluence, Notion, VS Code, and GitHub to keep diagrams grounded in actual implementation.
Run the agent toolkit in your own infrastructure under an MIT license and let MCP-compatible clients create, search, update, and export diagrams with OAuth or API tokens.
