# Hey SI

> Ride the wave. SI's got you. 🌊
> Hey SI (heysi.dev) helps complete beginners build their first app with AI coding tools. Hey SI is a brand of CanCapperZ LLC (Illinois, USA). Its mascot, SI the Yes Bot, is a cartoon robot character (not an actual AI) who is laid back, friendly, bubbly and kind, and answers "Hey SI, build me…" with "Yes!". Wordplay: "Hey SI" sounds like "hey sea", an invitation into a digital sea of possibilities. The main product is the Hey SI Starter Pack: 25 copy-paste prompts plus an AGENTS.md rules-file template, $12 launch price, delivered as Markdown files and a PDF.

## Key facts
- Audience: non-coders, founders, designers, hobbyists building a first app ("vibe coders").
- Works with: Cursor, Claude Code, Replit, Lovable, Bolt, and most chat-based AI coding tools.
- Covers 12 stages: Idea to Spec, Picking a Stack, Project Setup, AI Rules File (AGENTS.md), Building Step by Step, Debugging When Stuck, Fixing Broken Builds, Login & Database, Styling, Deploying (Vercel / Netlify), Writing a README, Next Steps.
- Safety: no account needed to buy; checkout provider handles payments (Hey SI never sees card numbers); HTTPS only; no tracking cookies. The pack teaches safe habits: never paste API keys into AI chats, keep secrets in .env, check for exposed keys before going live, review AI changes, make git save points.
- Does not include access to any AI tool and does not guarantee a working app.
