But have you ever wondered how these AI apps are created?
What if you could develop an AI app that reflects your unique ideas and solutions?
The good news is – yes you can build your AI app too. It doesn’t matter whether you’re an experienced developer or just a tech lover with no coding background.
You must be thinking how?
Well, keep reading this blog, as we’ve compiled everything you need to know about AI apps, including a step-by-step guide to building one.
Does It Take A Lot Of Effort To Develop An AI App?
Well, yes it takes lot of efforts to develop an AI app. AI is a complex technology and which is why a careful planning along with good expertise in machine learning and a huge amount of data is required to merge it in the app development process.
But, the efforts required depends on the complexity of the App and & it’s features. There are basically 3 types of AI Apps:
- Simple AI Apps: Simple AI apps can include basic chatbots or recommendation engines. The development process of simple AI apps usually takes 1 to 3 months and it generally requires a small team, making it easier to manage.
- Average AI Apps: These types of apps involve advanced features like AI-powered image recognition or chatbots with natural language processing. Which is why the development of average AI apps takes more time (3-6 months) and it requires a larger team, making the process more demanding.
- Complex AI Apps: It can take over a year to develop a complex apps with deep learning models or real-time machine learning. Complex apps usually need a significant investment in time & resources for its development.
The level of effort to develop an AI powered app depends on following factors:
- Availability of data: AI depends completely on data. The more complex your app, the more data you’ll need to train your AI models effectively. Collecting and processing large amounts of data can be really challenging.
- Existing tools and libraries: Fortunately, there are pre-built AI tools and libraries available that can streamline development process for certain functionalities. Using these tools can help reduce effort, especially for simpler apps.
- Your team’s expertise: Having a team with the necessary skills in AI, data science, and app development will significantly impact the effort required. You might need to invest in training or hire resources if your team is lacking in expertise.
6 Steps To Build An AI App
Creating an AI app involves a blend of old software development methods along with complex machine learning technology. Here is a detailed guide that will make you understand this process step by step:
1. Define The Problem And Set Goals
-
Identify the Need
The very first and the most important step is to understand the problem that you want your AI app to solve. What particular task or challenge your app is addressing? Like is it recognizing images, filtering spam, or giving personalized suggestions? Clearly defining the purpose will make the entire app development process easy.
-
Set SMART Goals
Once you got to know the problem that your AI app will solve, establish a SMART goal that is,
Specific
Measurable
Achievable
Relevant, and
Time-bound
Ask yourself – What functionalities this AI app will have and how you will measure its success?
2. Data Collection And Preparation
-
Data Gathering
AI models learn from data. You’ll need a lot of good-quality data that’s relevant to what your app does. This data can come from different places—like public datasets, how users interact, or even readings from sensors.
-
Data Pre-processing
Raw data cannot be used in its original form and which is why you will need to clean it and organize it. This includes removing duplicate data, fixing mistakes and a proper arrangement of data into a suitable structure that works well for your AI model. You will also need to use the data pre-processing techniques like data normalization and feature engineering.
3. Choosing The Right Tools And Frameworks
-
Development Tools
You can either choose low-code/no-code platforms or the old programming languages. It totally depends on your expertise in development and the complexity of your project. There are some popular choices in the industry that include Python with libraries like TensorFlow, PyTorch, or scikit-learn.
-
Pre-trained Models
If you are creating model from the scratch then it can be a tough process, you can use pre-trained models available through cloud services APIs. These models can save you a lot of development time because these models can be adjusted and modified as per your requirements.
4. Design And Train The AI Model
-
Model Selection
Choose an AI model that fits best for your problem type. For example, use Convolutional Neural Networks (CNNs) for image tasks, Recurrent Neural Networks (RNNs) for sequences like text, or Transformers for handling complex relationships in data.
-
Model Training
Train your model using the prepared data. This means feeding the data into the model and adjusting its settings to reduce the errors. Training can be resource-intensive, so using cloud resources might be needed for complex models.
5. Integrate The AI Model Into The App
-
Development Integration
In this step you will integrate the trained AI model into your AI mobile app or software application. This means writing code to link the interface of the app with the functions of the AI model. Frameworks like TensorFlow Lite or PyTorch Mobile can make this easier for mobile app development.
-
Test And Iterate
-
Rigorous Testing
Once you have integrated the AI model, check your app thoroughly to make sure that it functions as per your plan. Check its accuracy, speed, and how easy it is to use. Check for bugs and problems and fix them.
-
Iterative Improvement
AI development is a continuous process. Based on testing and feedback from users, you may need to refine your data, adjust the model’s structure, or retrain the model to achieve better performance over time.
Additional Considerations
When designing your AI app, focus on simplicity and clarity. Make it easy for users to understand and use. Ensure the app provides clear feedback so users know how to interact with its AI features smoothly.
Avoid biases in the data used by the AI to prevent unfair results. Use a wide range of relevant data to give accurate outcomes for everyone using the app.
To build trust, explain clearly how the AI makes decisions. This helps users feel confident in the app’s reliability.
If your app handles sensitive information, prioritize strong security measures. Encrypt data and follow privacy rules to protect users’ privacy effectively.
