App building and practical AI automation for small businesses in Ceredigion, Pembrokeshire and Carmarthenshire — quoting, bookings, invoicing chase-ups, document handling and the jobs that eat your evenings. Built professionally and priced keenly, by someone local. I will design, build and run a bespoke automation that fits exactly how your business works.
Based near Cardigan / Aberteifi · Croeso — happy to work with Welsh-speaking businesses
Know what’s due. Know what to do.
Mae rhagor o fanylion – astudiaethau achos, cwestiynau cyffredin a’r prisiau llawn – ar gael yn Saesneg. Cliciwch ‘English’ uchod, neu anfonwch e-bost ataf yn Gymraeg a byddaf yn ymateb.
Who this is for
Booking confirmations, check-in instructions, changeover schedules, review requests — written by hand, every single time. All of it can be sent automatically.
Quotes that take two evenings to write and invoices nobody chases. Automatic quote templates and polite payment reminders that go out on their own.
Gas safety, EICRs, tenancy renewals, deposit deadlines — tracked in spreadsheets and memory. One missed date is an expensive problem.
Supplier orders, price lists, rotas and social posts rebuilt from scratch each week. Templates and small tools cut them to minutes.
Client documents, renewal letters, appointment reminders. AI document handling reads, files and drafts them for you to sign off.
If the business stops when you are ill or on holiday, that is a systems problem, and it is fixable, usually more cheaply than you would think.
Plain pricing
First 5 local businesses, then £395
Sgwrs 60–90 munud, wyneb yn wyneb neu ar alwad, i drafod sut mae eich busnes a’i brosesau’n gweithio mewn gwirionedd. Byddwch yn cael adroddiad ysgrifenedig byr: y tri maes sy'n llyncu’ch amser fwyaf, ac yn union beth fyddai’n datrys pob un. Hefyd, bydd un awtomatiaeth gyflym a buddiol yn cael ei hadeiladu a’i gosod fel rhan o’r pris. Mae’r broses yn dechrau gyda galwad ffôn 15 munud am ddim, ac os nad oes unrhyw beth y byddai’n werth ei awtomeiddio, ni fyddwch yn talu.

The process
You show me how the admin really happens — the spreadsheets, the notebook, the 9pm emails.
You get a short, honest report: what to automate, what to leave alone, and what each fix is worth.
Fixed-price build of the pieces you choose. You see progress as it happens.
Handover in plain English — or a Care Plan and I will keep it running for you.
My own products
Not client mock-ups but real, live software with real users, payments and AI, all built by me. Whatever your project needs, the chances are I have already built something similar.
Upload a bill or forward an email — AI reads it, extracts the provider, cost and renewal date, sets reminders and finds where you’re overpaying. Free and paid plans, web and mobile.
If your project needs: AI document reading, automated reminders, subscriptions & payments

I am John, founder of Hattie Knows and a solution architect with over two decades of experience delivering complex systems, most recently for one of the UK’s largest environmental companies.
I live near Cardigan, which means you get someone who will sit at your kitchen table or come to your unit, who answers emails himself, and who will not disappear behind an agency account manager. Small, useful systems rather than six-month digital transformation programmes.
Common questions
Not at all. Everything I build is meant for people who would rather be running their business. If it needs a manual thicker than a page, I have built it wrong.
Practical things: software that reads a bill, invoice or certificate and files the details; drafts that write themselves for you to approve; reminders that fire before deadlines. No hype, and never AI for its own sake — sometimes the right fix is a simple form and a spreadsheet.
The conversation is 60–90 minutes. You will have the written report and your quick-win automation within a week.
Then you do not pay for the Health Check. It starts with a free 15-minute phone call, so if there is nothing worth doing we will usually both know before any money is involved — and if I only find that out in the session itself, I will not charge you for it. I would rather tell you the truth than sell you a project.
In-person visits cover roughly Aberystwyth to Haverfordwest to Carmarthen. Beyond that, everything works fine over a video call.
Tell me the task that eats the most of your week. If I cannot automate it, I will say so, and will probably tell you who can.
