<h1>Build Full-Stack Apps Using Chef by Convex</h1>
Convex has introduced Chef, an innovative AI agent designed for building full-stack applications seamlessly. Chef excels in both frontend and backend development, handling essential tasks such as real-time databases, file storage, authentication, and background jobs. Users can generate complex applications with just one prompt, and Chef manages the backend with Convex’s APIs.
One of the standout features of Chef is its ability to create complex applications, like an Instagram clone, by using user-provided prompts. It simplifies the development process by managing functions, tables, and file storage, thus allowing developers to focus on fine-tuning their apps.
The tool integrates additional functionalities that enhance Bolt’s browser-based application building, including a built-in code editor and a preview link for easy testing. Chef enables real-time database management and includes crucial features such as file storage and vector embeddings. These capabilities are vital for modern applications, allowing for searches within embedded data.
While Chef shows immense potential, users have reported some issues such as the tool occasionally deleting added features and encountering TypeScript errors. Despite these hiccups, Chef’s promise in creating and managing full-stack applications is evident.
To help users explore Chef’s capabilities, a detailed video tutorial is available. Initial tokens are provided for testing, with subsequent usage requiring a subscription or personal API keys. Chef represents a significant step forward in AI-powered code generation, making the process of building full-stack applications easier and more efficient.

Tu peux crée une application web de service de livraison de nourriture

Build a fully functional mobile application (Android-first) called “AudioPDF Converter” using React Native with Expo.
TECH STACK (STRICT)
React Native (Expo)
Styling: NativeWind (Tailwind for React Native)
APIs:
Speech-to-text: OpenAI Whisper API
Text-to-speech: OpenAI TTS API
File handling:
expo-document-picker
expo-file-system
expo-av (for audio playback)
CORE FEATURES (MUST WORK)
<ol>
<li>Audio → PDF</li>
</ol>
Allow user to pick audio file (mp3/wav)
Upload to API (Whisper) for transcription
Process text (basic formatting: paragraphs)
Generate PDF file
Save to device + allow sharing/download
<ol start="2">
<li>PDF → Audio</li>
</ol>
Allow user to pick PDF file
Extract text from PDF
Send text to TTS API
Play audio inside app
Allow user to download/share audio file
UI REQUIREMENTS
Clean, minimal mobile interface
Background: #F5F7FA
Buttons: blue gradient (#1E3A8A → #38BDF8)
Two main sections:
“Audio to PDF”
“PDF to Audio”
Use:
Card layout
Rounded corners (12–16px)
Clear upload buttons
Progress indicator
Result section (Download / Play)
SCREENS
Home Screen:
Two cards (Audio → PDF, PDF → Audio)
Converter Screen:
File picker
Convert button
Loading indicator
Result output
FUNCTIONAL REQUIREMENTS
Handle file permissions properly
Show loading state during API calls
Handle errors (invalid file, network issues)
Ensure files are saved locally
PROJECT STRUCTURE
/components
/screens
/services (API logic)
/utils (file handling)
IMPORTANT RULES
Do NOT write pseudo-code
Provide full working code
Include all imports
Ensure it runs with:
npm install
npx expo start
OUTPUT FORMAT
Full App.js or App.tsx
All required components
API integration code
Setup instructions at the end
REALITY CHECK (AGAIN)
PDF handling in React Native is messy
Whisper + TTS requires API key + internet
AI may still generate bugs — you must fix them
If you can’t debug, this project will stall.
BETTER STRATEGY (IF YOU’RE SERIOUS)
Start with:
Audio → Text only
Then Text → PDF
Then PDF → Audio
