AI integration in digital products: Leetio's proven approach

Why AI integration in digital products matters in 2025

In 2025, AI integration in digital products has become a standard part of product development. Static interfaces and generic user flows no longer meet user expectations. People interact daily with AI-powered systems across search, communication, and support, and expect similar responsiveness in every digital product they use. Companies now embed AI into onboarding, personalization, and decision logic, supported by large language models (LLMs), intelligent automation, and specialized AI tools. This adoption is shaping product strategies, influencing budget allocations, and redefining how digital products are deployed and improved over time.

Recent data shows:

• 92% of C-suite executives expect to increase AI spending in the next three years, and more than half (+55%) plan to boost it by at least 10% (McKinsey).

• OpenAI’s valuation and funding: With a $300 billion valuation in April 2025 following a $40 billion capital raise, it’s clear that significant investment is flowing into AI infrastructure (FutureSearch).

• 72% of organizations report regular use of generative AI in one or more functions — an increase from 65% earlier in the year (McKinsey).

At Leetio, AI is part of how we solve practical product challenges. We use it to reduce friction in onboarding, improve engagement, and extend the capabilities of static logic. Each AI implementation begins with a single question: What exactly needs to be improved, and is AI the right tool for the job? This focus helps us avoid overcomplicating things and ensures that AI works seamlessly as part of the product, not as an add-on.

AI-powered tools for seamless integration 

Integrating AI into digital products involves combining models, frameworks, and infrastructure components to create a seamless and practical experience. Each serves a specific role: parsing data, generating content, ensuring performance visibility, or meeting regulatory requirements.

This section outlines widely used AI tools in 2025, grouped by function. It includes cloud APIs, open-source frameworks, and infrastructure systems that support document processing, model inference, monitoring, and secure deployment.

Large Language models (LLMs) for generative AI and reasoning

These models are the foundation for most generative and reasoning-based AI features. They process natural language and produce output in the form of summaries, answers, predictions, or recommendations.

Used for: content generation, summarization, chatbots, classification, data extraction, translation, ranking, and reasoning.

• GPT‑4o (OpenAI): Multi-modal LLM with high performance across reasoning, summarization, and code. Used in both customer-facing chat interfaces and internal tools.

• Token and rate control (OpenAI API configs): Ensure that no single user or team exceeds quotas or sends sensitive data without limits.

• Presidio / Faker: Libraries for redacting PII or generating synthetic test data.

• Temporal / Kafka-based audit trails: Used for logging AI-related actions in critical systems for later review or investigation, supporting secure AI deployment

These tools form the technical foundation for modern AI products in 2025. While the specific stack varies depending on the project’s scope and industry, most implementations typically combine several key components: a language model, a retrieval system, a monitoring layer, and access controls. Selection depends on accuracy, latency, data sensitivity, and integration context.
Rather than relying on a single solution, production-grade AI requires assembling purpose-fit tools to ensure traceability, maintainability, and measurable value in real-world conditions.

Leetio’s process for building AI-driven products 

At Leetio, AI is evaluated the same way as any other technology. In both new and existing products, we define the problem first and apply AI only when it offers a clear advantage.

Our process for delivering production-ready AI features

1. Define the friction point: We begin by identifying exactly where users get stuck, drop off, or require additional guidance. AI is only considered when it solves a specific issue better than deterministic logic.

2. Map AI to product logic: We select the right type of model based on the task's requirements — generation, prediction, ranking, or classification. This might involve using off-the-shelf solutions like Qwen, Mistral, LLaMA, or Claude for language-based tasks, or combining them with embedding search and domain-specific classifiers where needed. Such choices are crucial for the reliable deployment of AI in production environments.

3. Prototype and test in flow: AI features are tested directly in the user flow (not in isolation) to evaluate output quality, latency, and UX implications.

4. Design fallback and override logic: Every AI decision is paired with a fallback: either a default state, a cached response, or a user-controlled override. This ensures stability even when models fail.

5. Observe, adjust, retrain: We monitor token usage, output quality, user interaction, and error rates. Based on real-world performance, we update prompts, adjust model selection, or apply fine-tuning. Given the rapid pace of AI development, this process is revisited regularly to incorporate newer tools, techniques, and benchmarks.

Technical perspective: LLMs, RAG, and deployment best practices 

• Prompt engineering pipelines: We utilize structured templates with slot injection, fallback values, and language conditioning (tone, persona, etc.) to ensure consistency. Prompts are versioned and tested as code.

• Model selection: GPT-4o is used for general-purpose tasks (such as summarization, classification, and generation), while domain-specific tasks may utilize Claude, Gemini, Mistral, or open-source models, depending on the requirements for cost, latency, and control. Such careful alignment ensures reliable machine learning models' performance in production.

• Retrieval-augmented generation (RAG): When outputs must reflect proprietary data (e.g., internal documents, catalogs, user data), we apply RAG pipelines with LangChain and a vector database (e.g., Pinecone, Qdrant).

• Async and batch logic: For non-blocking flows (e.g., enrichment, summarization, clustering), AI runs in queues (BullMQ) with retry logic and usage metering.

• Monitoring and observability: Token usage, model success rates, fallback activation, and feedback signals are logged and visualized for post-launch tuning.

• Security and compliance: Sensitive inputs are masked, logs are anonymized, and calls to external APIs are gated with token limits and rate control. When required, we route calls through on-prem or private models.

This approach keeps AI predictable, testable, and aligned with product goals. Each integration is scoped around measurable outcomes such as reducing manual effort, improving decision speed, or enhancing the user experience without adding unnecessary complexity.

Case study: How our approach works on a real project

In this section, we demonstrate how our AI integration process was applied in a real product scenario.

The project is SnapLog — a mobile and web application developed to optimize the collection and utilization of clinical data. From the beginning, it was clear that AI could play a role, but the scope, value, and implementation needed to be carefully defined.

SnapLog operates in a context where speed, accuracy, and minimal interaction are essential. The challenge was to identify whether and where AI could improve the workflow without introducing unnecessary complexity, risk, or long-term maintenance overhead. We focused on applying AI in a specific area where it could provide measurable and consistent value, demonstrating a practical example of AI adoption.

Each step of the process described earlier was applied in practice, and this section explains how we handled those stages in the context of this product.

Step 1: Defining the friction point in clinical workflows 

The core friction was manual documentation. Surgeons were manually recording patient and procedure data, which slowed their workflow and increased the likelihood of errors. The process didn’t scale, especially in high-pressure environments like operating rooms.

We analyzed the entire workflow and identified one step that consistently required repetitive effort: transcribing structured clinical data from handwritten or printed labels. This task created a clear opportunity for automation. It was high-frequency, followed predictable patterns, and required no subjective judgment.

Step 2: Mapping AI to product logic and model selection

Once the target use case was defined, we evaluated the best way to automate it. The task involved extracting known fields—such as patient ID, surgery type, and timestamp—from visual input and converting them into structured data. Generative models were not relevant in this case.

We mapped this logic to a computer vision pipeline, starting with Google OCR for initial testing. Later in the process, we prepared for a switch to a custom-trained model based on real-case data to improve accuracy in low-light or handwritten scenarios.

The AI component was specifically designed to handle this task. It did not interfere with the rest of the workflow, which was managed through standard UI and API logic.

Step 3: Prototyping and in-flow testing for performance 

We tested the AI pipeline directly within the data capture flow in the mobile app, under real usage conditions. This allowed us to evaluate model accuracy in real-world situations (lighting, camera angle, text quality) and measure total time from scan to result.

Performance benchmarks were defined before implementation. The AI pipeline had to return usable data in under three seconds on standard mobile hardware. Testing focused equally on speed, recognition accuracy, and how easily users could correct output when needed, highlighting practical aspects of AI deployment.

Step 4: Designing fallback and override logic for reliability

AI output was not always perfect. To avoid blocking the user or introducing risk, we implemented fallback behavior:

• If confidence was low, the result was highlighted for manual review.

• Users could always edit extracted fields before saving.

• Data could be submitted without AI if needed.

This fallback logic ensured the app remained usable even when AI didn’t perform as expected. AI was utilized to expedite the workflow without making the system overly dependent on it, ensuring a stable AI-powered application in production.

Step 5: Observing, adjusting, and retraining AI for improvement 

During testing and rollout, we monitored the frequency at which users edited or corrected AI-generated fields. This data revealed specific failure patterns, including text alignment issues, handwriting inconsistencies, and common field confusion.

These patterns informed the plan for Phase 2 of the AI pipeline:

• Collect real-world labeled data

• Fine-tune a domain-specific OCR model

• Improve field segmentation and confidence estimation

Decisions were made based on real user behavior and data collected during the testing process.

The SnapLog project demonstrates how our AI integration approach works in practice: a narrow scope, high relevance, and a transparent fallback. AI was applied only where it directly reduced friction, and only after its value was proven within the actual workflow.

We applied AI as a technical solution to enhance data entry speed and accuracy while maintaining the stability and simplicity of the rest of the product.

Final Thoughts

AI in product development depends on clear problem definition, reliable infrastructure, and measurable outcomes. The AI implementation should integrate seamlessly into the existing system architecture and facilitate long-term maintenance.

Teams typically start by identifying a single point where automation or prediction can enhance speed, accuracy, or decision quality. Each integration must be tested in real usage conditions and monitored over time.

At Leetio, we design and build AI features that are ready for production. We focus on technical clarity, practical architecture, and business value, without unnecessary layers or shortcuts.

If you're planning a new AI feature or want to enhance its functionality in your product, we can help define the scope, select the appropriate tools, and implement it in a manner that suits your system and team. We work closely with product and engineering teams to ensure that every AI component supports clear goals and runs reliably in production.
