WitWriter Bio Builder: From Awkward to Attractive in 3 Seconds

The Problem

Most dating app bios are forgettable. People spend $5 to $10 on boosts and templates, yet still sound "mid." I wanted to fix that with zero fluff.

The Solution

A single-page web app that turns one self-description into 3 AI-written bios (funny, flirty, smart, honest, or mysterious) tailored to Tinder, Bumble, Hinge, Instagram, LinkedIn, or custom.

Pricing

Free tier: 3 bios per session
Paid unlocks (one-time only):
• $4 to 24 hours
• $9 to 7 days
• $29 to lifetime

No subscriptions. Ever.

Built in <48 Hours

Stack: Next.js, Tailwind, OpenAI (gpt-4o-mini), Stripe Checkout, localStorage for session/access tracking
Tools: Lovable.dev + Bolt.new to one-shot prototype to manual polish
Deploy: Vercel, custom domain (witwriter.ai)
Design: Minimal white UI, cosmic purple (#7E57C2) accents, mobile-first, Inter font

Key Features

• One-click copy for each bio
• Tone + platform selectors (dropdowns)
• Smart prompt engineering: natural, platform-native, <150 chars
• Client-side gating: no backend, no auth, no bloat
• Analytics: local counters for generations/conversions (RevTrack-ready)

Outcome

• Live in 2 days
• First $29 lifetime sale in <6h
• Viral-ready for TikTok (10-sec demo: input to output to copy)
• Code open-sourced (GitHub)
• Proved: micro-SaaS can be fun, fast, and profitable without subscriptions

"Fuck subscriptions." My rule. WitWriter follows it.
