The questions
Why can non-technical founders now build software with AI?
Coding models crossed a quality threshold in late 2024, and a wave of tools (Lovable, Replit, Bolt, Emergent, Google AI Studio) now turn plain-English descri...
What tools should I start with (Cursor, Claude Code, Lovable, Replit, Bolt, v0)?
Lovable or Replit if you do not code, Claude Code or Codex if you can read code. Lovable gives 5 free build credits a day (Pro from $25 a month) and Replit C...
How do real founders ship an MVP with AI in days instead of months?
The pattern is consistent: scope one core workflow, prompt a working prototype in hours, put it in front of 5-10 real users within days, and iterate on live ...
What are the limits, when do I still need a real engineer?
Vibe coding gets you roughly 70% of the way: prototypes, internal tools, and early MVPs. The last 30% (security, scale, complex integrations, gnarly bugs) is...
What actually counts as vibe coding, and how is it different from serious AI-assisted engineering?
Karpathy's original meaning was specific: let the AI write everything and do not even read the code. Simon Willison drew the now-standard line: if you review...
How do I plan and prompt so the AI builds what I actually want?
The single biggest upgrade is to stop prompting features and start with a spec: brainstorm the idea into a written plan (a mini PRD), break it into small ste...
How do I keep my vibe-coded app from getting hacked?
AI tools routinely ship apps with API keys in the frontend and database security (like Supabase Row Level Security) switched off; scans found roughly 1 in 10...
How do I get my vibe-coded prototype ready for real users?
A demo that works for you and a product that survives strangers are different animals: before launch you need real authentication, database rules, environmen...
How do I add accounts, a database, and payments to my vibe-coded app?
Most builders now come with the backend built in: Lovable's built-in backend adds a database, sign-in and file storage as soon as you ask for them, and Repli...
What do I do when the AI gets stuck, loops, or breaks things it already built?
The 'fix this, break that' loop is the number one vibe-coding frustration, and it is usually a context problem: the session's memory is full and the AI is pa...
How much does vibe coding really cost, and how do I stop burning credits?
Plan on $20-100 a month while building seriously. App builders charge by usage: Lovable in credits from $25 a month, with chat free for planning, Bolt in tok...
Do I still need to learn to code, or is prompting enough?
You no longer need syntax, but you very much need computational thinking: how to break problems down, what a database or API is, and how to read what the AI ...
Can vibe-coded products become real businesses?
Yes, and the evidence is no longer anecdotal: Base44 sold to Wix for $80M six months after a solo founder started it, Pieter Levels' vibe-coded flight sim hi...
Can I vibe code a mobile app and get it into the App Store?
Yes: Replit's agent builds native mobile apps you can test on your phone and submit for App Store review, Google AI Studio builds native Android apps you can...
How do I avoid losing work? Version control for founders who don't code
The most common regret among new builders is losing a working version they cannot get back. The insurance policy is Git: think of it as unlimited save points...
Lovable, Replit, Bolt or Base44: which AI app builder should I use?
Lovable, for most non-technical founders building a first real web app; Replit when the app needs a real backend you will keep running and fixing. Lovable bu...
Claude Code, Codex or Cursor: which AI coding agent should I use?
Pick by the plan you already pay for and how you like to work: Claude Code to hand over long jobs, Codex to keep several tasks running in the cloud, Cursor t...
How do I vibe code an app or website with AI, step by step?
Pick one app builder, describe one small app, and improve it one change at a time. 1) Write half a page: who it is for, the three things it must do, and what...
How do I write a spec or PRD that an AI coding agent like Claude Code can build from?
Write a short spec the agent can check its own work against, not a long PRD. 1) State the outcome: who uses it, the job it does, and what done looks like as ...
How do I get started with Claude Code?
You need a paid Claude plan (Pro is $20 a month, $17 billed yearly) or a Claude Console account with prepaid API credits; the free Claude plan does not inclu...
