15-year-old's free Grok-style roast bot Lunaar hits 2,000 users in 4 days

A 15-year-old high schooler launched Lunaar, a completely free Grok-style roast-bot app that hit 2,000 users in 4 days — built because he refused to pay $40/month to get insulted by AI.
How it works:
- Create bots with names and personalities (savage roaster, passive-aggressive mentor, a pirate who hates Mondays); they stay in character and remember who they are.
- Group debates: pick 2+ bots, drop a topic, and a hidden orchestrator moderates as they argue.
- Bring your own API key — no subscription, no paywall.
He's been coding since age 8, reads every comment, and ships fixes daily. A textbook case of undercutting a $40/mo novelty product with a free BYOK clone and riding the emotional hook to fast growth.
