Why Sympho?

⏳ Time is the biggest challenge. Many developers want to build an MVP, launch a study project, or release a real AI Speech solution—but these apps take a lot of time to develop and test. That’s why I created Sympho: to help the community accelerate their AI Speech projects with a ready-to-use solution.

Features

• 🎨 Beautiful & Friendly UI/UX — built with Shadcn/ui style.
  Special thanks to the author of shadcn_flutter for his great package.

• 📱 Mobile App Ready to Publish — for both iOS and Android.

• 🎵 Local Audio Storage — generated audios are stored locally, no need for databases or third-party platforms.

• 🔐 Secure API Server — with authentication handling and middleware to verify user tokens.

• 🤖 ElevenLabs Integration — seamless AI Speech generation via ElevenLabs.io RESTful API.

• 🗝️ Environment-Based Security — use .env files to securely store API keys and secrets.

• 🐳 Docker Support — prebuilt Dockerfile for each API server, deploy with a single command.

• 📖 Clear Documentation — even beginners can use the solution without prior knowledge.
