Inspiration

We noticed how often people freeze or stumble when trying to craft the perfect opening line or reply in a romantic chat. In today’s fast-paced dating world, confidence often comes down to having the right words at the right moment. We asked ourselves: what if AI could become your personal “wingman,” analyzing your chat context and generating spot-on flirty responses in an instant?

What it does

Flirt AI leverages on-device screenshot analysis and server-side language models to deliver:

  • Subtle Openers when you want to break the ice.
  • Witty Replies to keep the conversation flowing.

How we built it

  • Platform & UI: Developed entirely in SwiftUI, using modern view composition and async/await for smooth image-to-AI flows.
  • AI Integration: Backend hosted on Cloudflare Workers, forwarding prompts to OpenAI’s GPT & Google Gemini
  • Screenshot Analysis: We use VisionKit to securely extract text and context from user screenshots—no data is stored on-device.
  • Monetization: Subscriptions and unlocks (e.g., “Unlimited Pick Lines,” ) are handled via RevenueCat, giving us unified cross-platform IAP management and real-time entitlement checks.

Challenges we ran into

  • Privacy & Permissions: Ensuring users feel safe granting screenshot access; we implemented on-device text extraction and explicit consent flows.
  • Subscription Edge Cases: Handling trial expirations, downgrades, and restore-purchases reliably across sandbox and production—RevenueCat’s webhooks and customer-info APIs were lifesavers.
  • UI Performance: Keeping the SwiftUI views responsive while waiting for API calls required careful state management and lightweight placeholder views.

Accomplishments that we're proud of

  • MVP in 48 Hours: From blank Xcode project to working prototype with screenshot upload, AI response, and live IAP gating.
  • Seamless RevenueCat Integration: Unified trial, monthly, and yearly plans with no flicker or UX jank.
  • Positive Early Feedback: Beta testers report 95% “would recommend” and cite the “one-tap charm boost” as game-changing.

What we learned

  • SwiftUI’s Power: How to architect a modular, data-driven UI that stays snappy under asynchronous workloads.
  • Prompt Engineering: Crafting context-aware templates that coax out playful, sincere, or bold tones from the same AI model.
  • IAP Best Practices: RevenueCat drastically simplifies cross-platform subscriptions but still demands rigorous testing of restore and entitlement flows.

What's next for Flirt AI

  • Tone Presets & Themes: “Movie-Quote Mode,” “Shakespearean Mode,” etc.
  • Integration with Chat Apps: One-tap sharing into WhatsApp, iMessage, and beyond.
  • Android Companion App: Bringing the same seamless experience to a wider audience.
