Their Pitch

Inspiring AGI to Benefit Humanity.

Our Take

An AI coding assistant that writes entire apps from plain English descriptions. Powered by Chinese GLM-4 models, so you get decent coding help for $3/month instead of paying OpenAI prices.

Deep Dive & Reality Check

Used For

  • +**Your React app breaks every time you copy-paste Stack Overflow code** → Describes your project structure and generates code that actually works in your environment
  • +**You're spending 4 hours debugging merge conflicts and lint errors** → AI automatically fixes the boring stuff so you can focus on building features
  • +**Manual coding tasks eat your entire evening** → Say "build a todo app with dark mode" and get working HTML/CSS/JS in 30 seconds
  • +Built-in web search and function calling - connects to APIs and pulls real data without you writing integration code
  • +Autonomous slide and poster generation - creates entire presentations from a single prompt

Best For

  • >Your weekend side project is stuck at 60% done because writing boilerplate after work is soul-crushing
  • >You're debugging the same JavaScript errors for the third hour and questioning your career choices
  • >Need a working prototype by Friday but your developer budget is three coffees and a prayer

Not For

  • -Enterprise teams needing compliance and security audits — this is a scrappy Chinese startup, not Microsoft
  • -Developers who want to understand every line of code — this generates fast, you debug later
  • -Teams already happy with GitHub Copilot — similar functionality but different model, not worth switching unless you're budget-conscious

Pairs With

  • *VS Code (where you'll paste the generated code and make your tweaks)
  • *GitHub (to actually version control the code it spits out)
  • *Vercel (to deploy those 5-minute prototypes and show off to clients)
  • *Claude (as backup when GLM-4 doesn't understand your weird edge case)
  • *Notion (to track which prompts generated the best code for future reference)

The Catch

  • !Documentation is thin and mostly in Chinese — you'll figure out features by trial and error
  • !No free tier mentioned, so you're paying $3/month even to try it out
  • !File upload limits and citation features are unclear — might hit walls with larger projects

Bottom Line

ChatGPT for coding that actually generates working prototypes in minutes, not broken snippets you'll spend hours fixing.
