AI Integration Services for Existing Products

AI integration services that add OpenAI, Claude and Gemini capabilities to the software you already run: summarization, generation, search, classification and copilots, with retrieval over your data, evals and cost control. Senior engineers, AI-accelerated delivery, inside your codebase.

What We Serve

Add AI to Your Product Without Rebuilding It

You do not need a new product to benefit from AI; you need the right feature in the product you have. Our AI integration services connect the OpenAI, Anthropic and Gemini APIs to your existing web app, SaaS platform or internal tools: drafting and summarizing, semantic search over your data, classification and routing, extraction from documents, and in-app copilots. We prototype against your real data first, prove quality with evals, then integrate in reviewed pull requests inside your codebase and design system, with caching, model routing and monitoring so costs stay predictable. AI coding tools speed up the engineering; senior engineers own architecture, security and data handling.

Our Approach

Prototype on Real Data, Prove With Evals, Integrate in Slices

Every integration starts with one question: what would this feature have to get right for users to trust it? We prototype the feature against a sample of your real data in days, write an eval set from real cases, and compare models on quality, latency and cost. Only then do we integrate: typed API layers, retrieval where grounding is needed, structured outputs, guardrails, and UX that shows confidence and allows editing. Each slice ships as a reviewed pull request with the evals running in CI and usage, cost and quality monitored in production. Data handling is agreed in writing before anything leaves your systems.

What Is AI Integration?

AI integration connects large language model APIs such as OpenAI, Claude and Gemini to existing software so it can summarize, generate, search, classify, extract or assist, using your own data for grounding and with the evals, guardrails and cost controls needed to run reliably in production.

The right feature

Summaries, drafts, search, classification, extraction or a copilot, chosen by user value.

Grounded in your data

Retrieval over documents and records so answers are specific and cited.

Measured quality

Evals from real cases run on every change.

Predictable cost

Model routing, caching and limits designed in from the start.

At Devoq Design, AI integration means useful features in the product you already have, delivered about 5x faster with AI-accelerated engineering and senior review.

Costs That Spiked

Every request to the largest model with no caching or routing.

No Way to Measure Quality

Prompt changes shipped without evals, breaking things silently.

Data Handling Questions

Nobody can say what leaves your systems and under which agreement.

Prototype That Will Not Scale

Frequently Asked Questions

What can AI integration add to our existing product?

Summaries and drafts, semantic search and question answering over your data, classification and routing, extraction from documents, personalized recommendations and in-app copilots. We help you pick the feature with the clearest user value first and prototype it on your real data.

How much do AI integration services cost?

It depends on the feature, the data sources, the models, compliance needs and the UX work inside your product. The prototype phase has a fixed price; the integration is scoped after the prototype proves quality, as a fixed price or a monthly retainer.

Which AI provider should we use: OpenAI, Claude or Gemini?

It depends on the task. We compare models on your eval set for quality, latency and cost, and often route between them. Open models can be used where data residency or cost demands it.

How do you keep our data private?

Data handling is agreed in writing before anything leaves your systems, providers are used under agreements that do not train on your data, access control is enforced at retrieval, and sensitive fields can be redacted before any call.

How do you control AI costs?

Model routing sends simple requests to cheaper models, caching avoids repeat calls, prompts are kept lean, usage limits protect against spikes, and cost per request is monitored in production from day one.

How is this about 5x faster than a traditional agency?

Four things add up: several AI-drafted options at once instead of one at a time, generated boilerplate and tests instead of hand-written setup, reusable component libraries instead of page-by-page builds, and automated checks on every change instead of a manual pass at the end. Review time stays the same; waiting time disappears.

Is AI-assisted work good enough, and is it safe?

AI never ships anything on its own. A senior lead reviews every design and every code change, automated tests and accessibility checks run on each one, and the code is plain TypeScript in your own repository. We do not send your customer data to AI tools without a written agreement.

Who owns the code, the design files and the accounts?

You do, from the first week. Figma, GitHub, CMS and hosting accounts are created under your company, and the contract assigns the IP to you. There is nothing to hand back at the end because it was always yours.

How do you charge: fixed price, monthly retainer or dedicated team?

All three, depending on the shape of the work. A fixed price when the scope is clear, a monthly retainer when the work keeps evolving, and a dedicated designer or engineer pair when you want capacity inside your own team. We recommend one after a short discovery call.

Do you work with companies in the US, UK, Canada or Australia?

Yes, most of our clients are there. Devoq Design has teams in India, Canada and the US, so every project has overlapping hours for reviews and stand-ups. Everything else runs async with recorded walkthroughs, decision logs and written updates in your Slack or Teams.

How do we get started?

Book a 30-minute call or send a short brief. We come back within a few working days with a scope, a plan and a price. Work starts after an NDA and IP assignment are signed and your accounts are set up.
