A real answer, from a real document

Not a mock-up. This is the product, answering a question about a staff handbook.

Weld AI answering a question about notice periods, showing a formatted table with source citation

Answer includes formatted table and exact source — Staff_Handbook_v4.2.docx

Your firm already has the answers. Finding them is the problem.

Document-heavy teams lose 20–30 minutes per person, per day, hunting for things they know exist.

🔍

Searching costs real money

Ten people losing 20 minutes a day is roughly £25,000 a year in time. Most firms cover the install cost in the first week.

🔁

Knowledge leaves when people do

What your experienced staff know is buried in your files. Weld AI makes it available to everyone, permanently.

🔒

Cloud AI isn't an option for you

You can't paste client contracts or HR files into ChatGPT. Weld AI keeps every document on your own server.

Up and running in a single day

No IT project, no site visit. We install remotely and your team is asking questions the same day.

2

Point it at your files

Copy your policies, contracts and manuals into one folder. PDF, Word, Excel, PowerPoint.

Simple enough to use without training

Six things your team will actually use every day.

📚

Every answer shows its source

Document name and page number, every time. Your staff can check it before they rely on it.

📁

Search by client or matter New

Name the folder in your question and Weld AI looks only there. Built for firms that file by client.

📝

Summarise a whole document New

A summary drawn from the entire file, not just the first few pages, and it tells you how much it covered.

💬

Follow-up questions work

"More detail on the first one?" It remembers the conversation, and picks it up again after you close the tab.

🔄

Adding documents takes seconds

Drop a file in the folder, click Refresh. Only the new and changed files get re-read.

🎨

It looks like yours

Your firm's name, colours and tagline on a clean, modern interface.

We bring the AI to your data, not your data to the AI

Your files are never uploaded. To write each answer, only your question and a few short excerpts, with identifiers removed, are sent out.

🗄️

Your files stay where they are

Documents are indexed on your own server and never stored anywhere else. Access is over HTTPS, encrypted in transit.

Frequently asked questions

The things people ask before booking a demo.

Do my documents leave my server? +

No. Your documents, the search index and your chat history stay on your server. To write an answer, Weld AI sends Anthropic's Claude your question, the recent conversation, the names of the files it quotes, and up to eight short excerpts with identifiers such as NI numbers, UTRs, bank details, emails and phone numbers removed. Anthropic does not use this data to train its models and deletes it within 30 days.

What servers does it run on? +

Weld AI supports four install configurations:

  • Windows PC or Workstation — Windows 10 (21H2+) or Windows 11, 8GB RAM minimum, WSL2 enabled by IT in advance (one PowerShell command). Most common for small firms.
  • Windows Server + Ubuntu VM — recommended for servers. A small Linux virtual machine runs inside your Windows Server via Hyper-V. Full network share support.
  • Linux Server — Ubuntu 22.04 or Debian 12. Simplest install, full network share support.
  • Windows Server Direct — alternative only, requires complex WSL2 setup. Ubuntu VM approach preferred.

What's the install process like, and do we need IT staff? +

Usually under one hour, remote over a Teams or Zoom screen-share. No engineer visit, no separate IT project. In most cases your team can start asking questions the same day. Day-to-day use needs no technical skill — staff open a browser and type a question, and adding new documents is just copying a file into a folder and clicking Refresh.

What document formats does it support? +

PDF, Word (.docx, .doc), PowerPoint (.pptx), Excel (.xlsx, .csv), and plain text files. Most business documents are supported out of the box.

What happens when I add new documents? +

Copy the file into your documents folder and click Refresh in the app. Only new or changed files are re-indexed — the process takes seconds for most documents.

How much does it cost to run? +

Installation is from £350 (remote, includes 30 days support). The only ongoing cost is the AI usage — typically £2–5 per month for a small business, paid directly to the AI provider. No monthly subscription to Weld AI.

Where can our documents live? OneDrive, network drives, file servers? +

Local drives (C:, D:, E:, USB) work as long as they're connected at startup.

OneDrive or SharePoint synced to the PC works, provided the documents folder is set to "Always keep on this device" in File Explorer. Cloud-icon files aren't stored locally and can't be indexed until downloaded.

Network mapped drives aren't supported on Windows installs due to a Docker on Windows limitation. If your documents only live on a file server, we install Weld AI directly on the server (Windows Server or Linux) — that gives full network-share support.

We'll advise on the best approach during the pre-installation review.

Is this suitable for our industry? +

Weld AI works best for businesses with a significant volume of internal documents — policies, procedures, contracts, technical manuals, compliance guides. It works particularly well for accountancy practices, solicitors, HR firms, and engineering companies. If your team regularly spends time searching for information they know exists, it's a strong fit.
