AI integration that ships, not AI theater.

We integrate AI into real products — LLM features, document intelligence, retrieval, agents, and on-device models — with evaluation suites and cost controls, not demos that die in a slide deck. Senior European engineers, full-time overlap with your US or UK workday.

Proof, not promises

We ship AI in our own products.

Before we integrate AI into your product, look at how we use it in ours — shipped software, not concept videos.

libro — local document AI

Personal accounting that AI-parses financial PDFs and matches payments to invoices — entirely on-device. No SaaS, no data leaving the machine.

Bridge — agent-driven ops

The console we run our own studio on: AI agents handle research, drafting, and busywork under human review.

An AI-native workflow

AI is wired into every layer of how we build — design, code generation, testing, review — which is why our quotes come in lower.

We build native Mac apps too — several are free to download, so you can judge our engineering before you hire us.

What we build

From one LLM feature to a full AI workflow.

LLM features in your product

Summarization, extraction, classification, drafting, translation — the focused features your users actually use, built into your existing web, mobile, or desktop app.

Document intelligence

PDFs, invoices, contracts, and scans turned into structured data — parsing pipelines with human-review fallbacks where accuracy is critical.

RAG & knowledge search

Ask-your-data search over your docs, tickets, and wikis — retrieval pipelines with citations, permissions, and freshness handled properly.

AI agents & automation

Multi-step workflows that research, draft, reconcile, and file — with guardrails, audit logs, and a human in the loop where it matters.

Local & on-device AI

When data can't leave the building: open-weight models on your infrastructure, or on-device AI on Apple Silicon — like our own libro.

Model strategy, evals & cost

Provider selection, evaluation suites, model routing, caching, and token budgets — so quality is measured and the invoice is predictable.

No AI theater

Production AI is an engineering problem.

Need the app around the AI as well? We build native macOS apps and React Native apps for iOS & Android — AI included where it earns its keep.

How it works

Prototype in weeks, hardened for production.

01

Use-case scoping

30 minutes. We find where AI actually pays off in your product — and tell you where it doesn't.

02

Prototype on your data

A working feature on your real data in 1–2 weeks, with a fixed USD quote up front.

03

Evals & hardening

Evaluation suite, guardrails, fallbacks, cost controls — the unglamorous work that makes AI reliable.

04

Ship & monitor

Production rollout with quality and cost dashboards, plus iteration as models improve.

Why Co Digit

Senior EU engineering, on your clock.

We work your hours
Full-time overlap with the US East Coast day (8:00–16:00 ET) and UK hours. Standups, Slack, and reviews in real time.
European rates
The technical depth of a top agency at a fraction of US agency pricing. Billed in USD, card or ACH.
Direct line to the engineer
You talk to the person writing the code and the prompts — no project-manager telephone game.
NDA standard
Signed before the first call. Your code, prompts, and data are yours from the first commit.
FAQ

Questions founders ask us about AI.

Which AI models and providers do you work with?

Anthropic Claude, OpenAI, and Google Gemini for hosted models, plus local open-weight models when data can't leave your infrastructure. We pick the model per use case based on quality, latency, and cost — and design the integration so you can switch providers without a rewrite.

Can AI features run without sending data to the cloud?

Yes. We build local-first AI where it fits: on-device models on Apple Silicon and local pipelines for sensitive documents. Our own accounting app, libro, parses financial PDFs with AI entirely on the user's machine — no SaaS, no data leaving the laptop.

How do you keep AI API costs under control?

Cost is an engineering constraint from day one: model routing (small models for simple calls, frontier models where quality matters), caching, batching, token budgets with alerts, and per-feature cost dashboards. You'll know the unit cost of every AI feature before it ships.

Do we actually need a chatbot?

Usually not. Most products get more value from targeted AI features — summarization, extraction, search, classification, automation — than from an open-ended chat window. If AI isn't the right answer for your problem, we'll say so on the first call.

How fast can we have a working prototype?

A working prototype on your real data typically takes one to two weeks. We then harden it with an evaluation suite, guardrails, and cost controls before production. Scoping call first, fixed quote in USD within 48 hours.

Who owns the code, prompts, and evaluation data?

You do — code, prompts, evals, and fine-tuned artifacts, from the first commit. We sign your NDA before the first call, and your data is never used to train anyone's models.

Have an AI feature in mind?

Tell us the problem — not the model. You'll get a reply from the engineer who'd build it, within one business day, in your time zone.
