AI-Powered Email Writer Android Application

Android Developer Needed — AI Email Writer App Project Overview I am looking for an experienced Android developer to build a complete, polished AI-powered Email Writer application. The app should allow users to generate professional emails using AI by entering a purpose/context and selecting options such as email type, tone, length, and language. IMPORTANT — REFERENCE APP The new app should look and feel as close as possible to the reference application, including its overall UI, UX, layouts, navigation, colors, components, screens, and user flow. Reference app: https://leviticusstream.gumroad.com/l/ai-email-writer-sorce-code Please review this reference before submitting your proposal. I want the finished application to closely reproduce the reference app's: Overall visual style Screen layouts Navigation Color palette Typography Buttons and input fields Cards and selectors Icons and spacing Email generation interface Email editing interface History Favorites Search Settings Dark mode Loading and empty states Overall user experience The reference should be treated as the primary UI/UX specification. The developer must build the app independently with a new codebase. Do not copy proprietary source code, logos, copyrighted graphics, or unauthorized assets. Use my own branding and properly licensed/original assets while maintaining the same overall design direction. Core Features AI Email Generation Integrate an AI/LLM API such as Groq or another suitable provider. Users should be able to: Enter recipient information. Describe the purpose/context of the email. Select email type. Select tone. Select email length. Select language. Generate the email. Edit the generated subject and body. Copy, share, save, or favorite the email. Tones Include at least: Professional Friendly Formal Casual Persuasive Empathetic Assertive Diplomatic Enthusiastic Concise Email Types Include at least: Business Job Application Sales Customer Support Follow-Up Thank You Apology Invitation Academic Cold Outreach Complaint Request Meeting Networking Recommendation Resignation Cover Letter Reminder Congratulations Introduction The architecture should make it easy to add more types later. Length Short Medium Long Languages At minimum: English Spanish French German Italian Portuguese Arabic Chinese Japanese The AI should respect the selected language, tone, type, and length. Email Editing Users must be able to edit: Recipient Subject Email body Generated content must not be locked. Users should be able to modify an email before saving, copying, or sharing it. Email History Implement a local email history system. Users should be able to: View generated emails Open emails Edit saved emails Delete emails Favorite/unfavorite emails Copy emails Share emails History should be stored locally on the device. No mandatory account should be required for basic history functionality. Search & Sorting Search email history by: Recipient Subject Purpose Content Sorting options: Newest first Oldest first Favorites UI/UX The UI is extremely important. The app should closely follow the reference application's overall design and experience while using original implementation/assets.

Requirements

Modern Material Design 3 Clean navigation Attractive buttons and input fields Cards and selectors Consistent typography Proper spacing Appropriate icons Smooth transitions where appropriate Loading states Error states Empty states Light mode Automatic dark mode Portrait support Landscape support Responsive layouts The result should look like a professional commercial application, not a basic prototype. Settings Include a Settings screen with options such as: AI API configuration Default language Default tone Default email length Theme About Privacy information API credentials must not be hard-coded into the source code. If the user enters an API key locally, it should be stored using appropriate Android secure storage. Privacy & Security The app should follow a local-first approach for email history.

Requirements

No unnecessary user data collection No mandatory account for local history Secure API-key storage No hard-coded private API keys Proper handling of API errors Clear documentation of what data is sent to the AI provider Please explain your API-key security approach in your proposal. Technical Requirements Preferred: Native Android Kotlin Jetpack Compose Material Design 3 Room or equivalent local database Modern Android architecture REST/API integration Secure local storage Clean, maintainable code The project must be professionally structured so another developer can maintain and extend it. Monetization-Ready The architecture should allow future integration of: Google AdMob Monthly/yearly subscriptions In-app purchases Premium features Usage limits Free/premium plans AdMob and subscriptions can be added separately if not included in the initial scope, but the project should be designed to support them later without a major rewrite. Deliverables The developer must provide: Complete Android Studio project Complete source code All resources Gradle configuration Complete UI AI API integration All requested tones All requested email types All requested languages Email editing History Favorites Search Sorting Copy/share Settings Dark mode Portrait/landscape support Local database Secure API-key storage Testable release APK Build instructions AI API configuration instructions Basic project documentation The complete source code must be delivered at the end of the project. Testing Before final delivery, verify: AI generation works All tones work All email types work All languages work Length options work Editing works History persists correctly Favorites work Search works Sorting works Copy/share work Dark mode works Portrait/landscape work API errors are handled Invalid API keys are handled App does not crash during normal use A final working APK must be provided for testing.
