Product / LyricCard
Turn emotion into lyric cards, songs, and shareable video moments.
LyricCard is an iOS creative app that helps users turn a feeling, occasion, or message into a designed card, AI-generated lyrics, optional audio, and a vertical MP4 ready for sharing.
Product Demo
The current demo shows the share-ready vertical format the product is designed to generate after request creation, lyric output, media assembly, and render completion.
LyricCard starts with a situation, message, or feeling. From there, the app guides the user through request creation, lyric generation, visual card layout, optional audio, render status, and final playback.
What It Does
LyricCard combines request creation, lyric generation, card design, upload, job creation, polling, playback, and sharing into one product flow. The result is a designed artifact that can move from prompt to final MP4 without breaking into separate tools.
Product Positioning
ThalaStudio is the broader creative ecosystem. LyricCard is one focused product inside it, built around emotional prompts, lyric output, media generation, and shareable creative delivery.
Product Highlights
SwiftUI screens handle request creation, card editing, rendering, purchase state, push registration, network requests, and video job playback.
A Cloudflare Worker API coordinates requests, lyric generation, uploads, jobs, credits, sync flows, share routes, and media delivery.
D1 tracks requests, media jobs, push tokens, and usage records while R2 stores card images, final videos, TTS assets, and overlays.
A Render-hosted mixer service uses FFmpeg-based processing to turn image, audio, and effect inputs into a fixed-length vertical MP4.
How It Works
Start with a feeling, occasion, greeting, or message and send the request from the app.
Shape the visual card, text layout, and media ingredients that define the final moment.
The backend creates the job, orchestrates providers, and sends assets through the mixer pipeline.
The app tracks job status, retrieves the finished media, and plays the rendered output back in-app.
The final vertical MP4 is ready for direct sharing as a creative greeting-card style video artifact.
Architecture
LyricCard runs through an iOS SwiftUI app, a Cloudflare Worker API layer, D1 and R2 for data and media, external providers for content generation, and a Render-based mixer service for final video output.
