Local AI · Prototype

Private document assistant

Ask questions of your own documents, with answers that cite their source, on your own computer.

Let's talk

A prototype that indexes a folder of Word, Excel, PDF and scanned documents and answers questions with a language model running locally, so files never leave your machine. It shows the passages each answer came from. A proper interface is the next step.

What it covers

  • Reads Office files, PDFs and scanned pages (OCR)
  • Answers cite the passages they used
  • Runs on your own hardware with a local model
  • Typo-tolerant search
  • Access rules to be added before team use

Built for

Offices with contracts, policies and manuals they cannot upload to a public chatbot.

Screens on this site are illustrations with invented sample data. Tax rules and e-invoicing support are being verified with qualified advisers and official sources. Nothing here is a statement of filed or certified compliance.

How we would build it

  1. 01

    Listen

    We learn how your work runs today: who does what, with which files and rules.

  2. 02

    Design

    You see screens and a fixed scope with a plan and a price before we build.

  3. 03

    Build

    We deliver in short stages with live demos, so you steer as it takes shape.

  4. 04

    Support

    We deploy, train your team, and stay for fixes and the next improvements.

How do you price a project?

After the design step you receive a fixed scope, a plan and a price. Work outside that scope is quoted separately, before it starts.

Who owns the system and the data?

You own your data. Ownership and licensing of the code are agreed in writing before work starts.

What happens after launch?

We deploy, train your team and stay available for fixes and improvements, under a support arrangement agreed up front.
