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 language.
Generate the email.
Edit the generated subject and body.
Copy, share, save, or favorite the email.

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.

Source Code & Ownership

I require the complete Android Studio project and source code.

The app must not be locked to the developer's account or infrastructure.

Third-party libraries/assets must have appropriate licenses for the intended use.

The developer must not use stolen, pirated, or unauthorized code/assets.

Proposal Requirements

Please do not send a generic proposal.

Include:

Examples of Android apps you have developed.
Your Kotlin/Jetpack Compose experience.
Your AI/LLM API integration experience.
Examples of AI apps you have built, if available.
Your recommended AI API and why.
How you will securely handle the API key.
Estimated development time.
Fixed project price.
What is included in your price.
Confirmation that you will provide the complete source code.
Confirmation that you reviewed the reference application.
REQUIRED

Start your proposal with:

"AI EMAIL APP"

Also include:

"I have reviewed the reference AI Email Writer application and can reproduce its UI/UX, screen structure, functionality, and overall visual style in a newly developed Android application."

Generic proposals that do not address the requirements above may be ignored.

Final Goal

Build a polished Android AI Email Writer application that provides the same overall type of experience and very similar visual presentation as the reference application, while using a new codebase, original/properly licensed assets, and my own branding.

The application should be ready for future customization, monetization, and Google Play Store publication.
