FAQ

Questions, answered.

Straight answers about cost, timing, quality and ownership.

How much does it cost to build an AI Assistant?

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 an AI Assistant?

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.

Will the assistant make things up?

It answers from your content and shows sources, says when it doesn't know and hands over to a person. We measure accuracy with evaluation sets before launch.

Where can it live?

On your website, inside your web or mobile app, in Slack, Teams or WhatsApp — one assistant, several channels.

Can it take actions, not just answer?

Yes. It can check orders, book appointments or create tickets through your APIs, with approval steps where needed.

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.
