AI appdevelopment services for products that use AI in real workflows, not just in demos.

We build web and mobile apps where AI does real work: extracting data from documents, recommending products, searching by image, automating reviews. Product, data and engineering in one team, from the first prototype to production.
Discuss your AI app

A demo takes a weekend. A reliable AI product takes engineering.

Calling a model API is the easy part. The hard part is everything around it: clean data, prompts and models that hold up on real inputs, costs that don't explode with usage, fallbacks when the model is wrong and an app people trust. That's the part we build.

Why AI features stall before production

01

Works on the demo, fails on real data

Messy documents, edge cases and unexpected inputs break a prototype that looked great.
02

Answers you can't trust

Wrong or invented outputs reach users because nothing checks them.
03

Costs grow with every user

Model calls, tokens and GPU time get expensive once real traffic arrives.
04

No path from notebook to app

A data scientist's model works locally, but nobody has built the API, app and pipeline around it.
05

AI-built code that doesn't scale

An app generated with AI tools runs, but security, structure and tests are missing.
06

Unclear where AI adds value

The team wants AI in the product but can't say which workflow it should improve first.

Where AI pays off in a product

We start from the workflow you want to improve, then pick the model, not the other way around.

Document processing

  • Data extracted from PDFs and scans
  • Calculations checked automatically
  • Reports and approvals automated

Computer vision

  • Search by image
  • Image tagging and classification
  • Visual checks in mobile apps

Recommendations and search

  • Personalized product discovery
  • Text and image search
  • Ranking tuned on your data

Workflow automation

  • LLM assistants inside your app
  • Routine reviews and checks automated
  • People stay in the loop where it matters

Signs you need an AI development company

If these sound familiar, an experienced team will save you months of trial and error.

1

Your prototype hit a wall

The proof of concept worked, but accuracy, speed or cost stops you from launching.

2

Manual work eats your team

People read documents, check numbers or tag images by hand every day.

3

Competitors ship AI features

Buyers ask why your product can't do what others now offer.

4

You have data and no plan

Years of documents, images or transactions sit unused.

5

Nobody owns ML in-house

Your engineers build the product well but haven't shipped models to production.

6

Investors want an AI MVP

You need a working product to show, not slides about a future one.

From idea to an AI product in production

01

Discovery

We map the workflow, review your data and agree how we'll measure if the AI feature works.

02

Prototype

A quick test of models and approaches on your real data, before building the full product.

03

MVP build

The AI feature, the app around it, and the checks that catch wrong outputs.

04

Launch

Release to real users with monitoring of quality, speed and cost.

05

Improve

We tune models, prompts and infrastructure based on how people actually use the product.

Why Gilzor

We build AI into products people use every day, and we care as much about the app around the model as about the model itself.

What we bring

AI and product skills together

ML engineers, web and mobile developers, designers and QA in one team.

Production experience

On an airline web and mobile app we built, baggage weigh-in became 33% faster.

Track record

70+ products launched for startups, SMBs and product companies.

Funded clients

The biggest fundraising round by one startup we worked with was $12M.

Quick start

Projects can start in about two weeks.

What makes us different

Workflow first

We pick the model to fit the problem, not the hype.

Checks around the model

Wrong outputs are caught before they reach users.

Costs in view

We watch model and infrastructure spend from the first prototype.

Honest advice

If AI isn't the right tool for a task, we say so.

Overlap with US hours

Our team in Europe overlaps with part of the US working day.

What our clients
frequently ask

What do your AI app development services include?

Discovery, prototyping, model selection or training, the web or mobile app around the AI feature, data pipelines, testing, launch and ongoing improvement. You can hire us for the whole product or for one part of it.

Can you build an AI MVP for a startup?

Yes. We usually start with a 2-week Discovery Sprint to test the approach on your data, then build an MVP with the core AI feature and the app around it.

Do you train custom models or use existing APIs?

Both. Many products work well on existing models with good prompts and checks. When your data or task needs it, we train and tune models in Python and TensorFlow.

Do you work as a computer vision development company?

Yes, as part of our AI work: image search, recognition and classification inside web and mobile apps. Tell us what your images look like and what you need from them.

We built an app with AI coding tools. Can you take it to production?

Yes. We audit it, fix security and structure issues, add tests and prepare it for real users. See our service for taking AI-built apps to production.

How is AI development priced?

A Discovery Sprint is a fixed price. After that, an MVP is usually a fixed price based on the agreed scope, and ongoing work is monthly with a dedicated team.

How do you handle our data?

We agree with you upfront where data is stored, who can access it and which model providers may process it. Access is limited to the people working on your project.
