Our Approach:

We built a custom LLM solution (alternative to gpt-4-vision-preview, such as GPT-3.5) that seamlessly integrates with Android apps. This in-house LLM prioritizes data privacy by keeping all processing on the user's device, ensuring no data transmission to external servers.

Key Features:

  • Customization: Adapt the LLM to your specific app's needs, allowing for a tailored user experience.

  • Advanced Functionality: The LLM performs complex tasks like captcha handling, user following on social platforms, and form filling with user-provided information.

  • Continuous Learning: User feedback integration ensures the LLM continuously improves accuracy and adapts to user preferences.

  • Seamless Integration: The LLM integrates flawlessly with your existing Android app, creating a smooth and intuitive user experience.

  • Enhanced Efficiency: We optimized the LLM for efficient on-device processing, minimizing resource consumption on smartphones.


We successfully developed a fully functional in-house LLM model that operates independently, prioritizing user data privacy.


  • Enhanced User Experience: Users can interact with their apps through natural language instructions, simplifying navigation and task completion.

  • Improved Security: Data privacy is paramount. This LLM solution ensures no user data ever leaves the device.

  • Increased Accessibility: The LLM can be a valuable tool for users with dexterity limitations or visual impairments.

  • Future-Proof Technology: The LLM framework allows for continuous learning and adaptation, enabling the model to handle even more complex tasks in the future.

This project showcases Codersarts' expertise in:

  • LLM Development: Building custom LLM solutions for specific applications.

  • Android App Development: Flawless integration of LLMs with Android apps.

  • Data Privacy: Prioritizing user data security and on-device processing.

Android App Navigation Chatbot with In-House LLM

Tech Stack:

  • Programming Language: Python

  • Large Language Model (LLM): GPT-3.5 (alternative to gpt-4-vision-preview)

  • Android Development Tools: Android Studio, Android Debug Bridge (ADB)

  • Potential Additional Libraries: TensorFlow (for LLM integration), Natural Language Processing (NLP) libraries

Learning Resources:

  • GPT-3.5 API documentation and tutorials

  • Android app development tutorials with Python

  • Android Debug Bridge (ADB) commands and usage guides

  • NLP libraries like spaCy or NLTK for text processing (if needed)

  • Security best practices for mobile app development

Use Cases:

  • Android App Navigation Assistant: The LLM chatbot acts as a virtual assistant, understanding user instructions and navigating through smartphone applications to perform actions. (e.g., "Open Instagram and like the latest post").

  • Accessibility Tool: The chatbot can be used for accessibility purposes, providing voice-controlled assistance for users with visual impairments or dexterity limitations.

  • Enhanced Security: The chatbot can be trained to identify and bypass captchas, reducing user frustration and improving login efficiency. (Note: Bypassing captchas may violate terms of service for some platforms.)

Project Challenges:

Model Adaptation and Automation:

  • Fine-tuning the GPT-3.5 LLM for specific smartphone app tasks through transfer learning techniques.

  • Developing a framework that automates user instructions and translates them into app interactions using ADB or other accessibility tools.

Model Efficiency and Data Privacy:

  • Optimizing the LLM for efficient on-device processing to minimize resource consumption on smartphones.

  • Implementing techniques like federated learning or on-device training to ensure data privacy by not sending user data to external servers.

Customization and Feedback Integration:

  • Developing a user-friendly interface for customizing the chatbot's behavior for different apps and tasks.

  • Integrating user feedback mechanisms to continuously improve the LLM's accuracy and adaptability.


In-House LLM Development:

  • This project focuses on building a custom LLM framework similar to AppAgent but utilizing GPT-3.5 instead of gpt-4-vision-preview.

  • The goal is to achieve high accuracy (99.99%) and human-like behavior while maintaining complete data privacy on the user's device.

Enhancing Model Accuracy:

  • The LLM will be trained to perform complex tasks like captcha handling, following users on platforms, and form filling based on user-provided data.

  • Resources will be provided to guide users on training the model for even more complex tasks in the future.

Note: Achieving 99.99% accuracy with current LLM technology might be challenging depending on the task complexity. The project should set realistic expectations and focus on iterative improvement through training and user feedback.

This project offers an exciting opportunity to explore the potential of LLMs in smartphone app navigation while emphasizing data privacy. It requires expertise in LLM adaptation, Android development, and security best practices.
