How it works

Idea to production. In three steps.

AI does the heavy lifting. Senior engineers make every decision that matters.

Who it’s for

Built for founders and product teams.

Here is where it works best, and where it doesn’t.

Finance teams

Invoices and receipts processed without manual entry.

Legal teams

Key terms and risks pulled from contracts in seconds.

Logistics

Bills of lading, customs and delivery documents digitised.

Insurance and lending

Claims and applications checked automatically.

HR and onboarding

IDs, contracts and certificates captured and verified.

Healthcare admin

Referrals and forms turned into structured data.

Not the right fit

A handful of documents a month.
Handwriting so poor that people cannot read it either.
Certified compliance from day one, such as HIPAA or PCI audits.
Open-ended research without a defined first release.

How we work

Six stages, one team.

All services

Pricing

Start free. Ship at a fixed price.

Two steps. The prototype costs nothing, and the release costs exactly what we agree.

FAQ

Questions, answered.

Straight answers about cost, timing, quality and ownership.

How much does it cost to build a Document AI?

The price is fixed for the agreed scope and set before work starts. You first get a free working prototype of the core flow in 1 day, then a fixed price and release date for the production version.

How long does it take to build a Document AI?

A working prototype takes 1 day. The production release date is agreed upfront and depends on the scope; AI speed with senior engineering makes it much faster than classic development.

How accurate is it?

We measure accuracy on your real documents before launch; uncertain fields are flagged for a quick human check.

Which documents can it read?

PDFs, scans, photos and email attachments — invoices, contracts, forms, IDs and more, in many languages.

Where does the data go?

Straight into your ERP, CRM, accounting tool or database, through their APIs.

Is the prototype really free?

Yes, with no commitment. After a 30-minute call we build a working prototype of your core flow in 1 day, and then you decide whether to continue to the release.

Will the price go up during the build?

No. The price is fixed for the agreed scope. Anything new you want to add mid-build is priced separately and built only after you approve it.

Who owns the code?

You do, 100%. The source code, repository and accounts are yours, and the release ships to production under your name.

Is AI-written code safe to ship to production?

It ships only after senior review. Senior engineers own the architecture, security and code quality, and automated tests run on every change.
