5 Frequently Asked Questions About AI App Development Companies

How much does it cost to build an AI app?

Simple AI integrations using third-party APIs (e.g., OpenAI or Anthropic) or off-the-shelf builds can cost about $5,000-$20,000. For instance, a chatbot or search engine recommendation system.  

More complex AI applications with custom workflows, multiple integrations, and a polished UI range between $100,000 and $250,000. Enterprise-level builds that require custom-trained models and large-scale data pipelines can cost over $500,000. 

How long does it take to build an AI app?

A basic MVP using a pre-trained or off-the-shelf model can take around 2-3 months. A mid-complexity app, with custom features, multiple data sources, or advanced workflows, may need at least 4-11 months to build. 

Ultimately, the AI application development timeline will depend on your project's scope, complexity, security and compliance requirements, and business readiness. 

What is the difference between using an existing AI API vs. building a custom model?

An existing AI API (e.g., OpenAI, Anthropic, Gemini) offers access to a pre-trained model through a paid subscription or usage fee. This model is faster to launch, has lower upfront costs, and requires no in-house AI expertise to maintain. 

A custom model is built and trained on your own data, providing more control over accuracy, behavior, and proprietary advantage. However, it costs significantly more, takes longer, and requires ongoing retraining and infrastructure.  

Consider choosing custom AI if you have niche domain data, strict compliance requirements, and AI is your main differentiator. 

What AI features are worth adding to an existing app?

The AI features worth adding to an existing app will depend on your core business needs, goals, and existing tech stack. 

For companies moving beyond isolated AI features, AI-native workflow redesign involves rethinking processes around AI rather than simply adding AI tools to existing workflows.

The same study also found that 44.4% of tech founders believe that automation is the most beneficial AI feature, followed by customer personalization (22.2%) and AI-assisted productivity features (22.2%). 

How do you ensure data privacy and data security?

Reputable AI app development companies will isolate your data through encrypted storage (at rest and in transit), strict access controls, and clear data-handling agreements with any third-party AI providers used. 

To confirm the AI application development company’s legitimacy, consider the following: 

  • Search for compliance certifications relevant to your industry (e.g., HIPAA, SOC2).  
  • Require a written data processing agreement (DPA), which outlines where data is stored, who has access, and how it’s deleted.  
  • Obtain a copy of the AI API’s Terms of Agreement. It should explicitly state that the company and its model do not use your data for training.
