What it does
Translates a whole folder into plain English, or any language you like, right on your machine.
Summarises it in seconds and points to the exact page, so you can check it yourself.
Pulls the figures together and builds you one clean spreadsheet.
Drafts the reply in your own words and saves it as a new file. Your original is never touched.
Personal over time
Inkwell isn't a stranger you re-introduce yourself to every time. Point it at the folders that matter, the documents, the emails, the notes, and tell it the things worth remembering, like "I run a florist" or "my main client is Northwind". The more of your world it can see, the more it has to work with, and the more personal its help becomes. Your files stay exactly where they are; Inkwell simply reads them in place when you ask.
It does this without sending a thing off your computer, and without changing the AI itself. Your files and your notes stay on your machine, read only when you ask. Nothing is uploaded to train a model somewhere. The intelligence is yours, and so is everything you point it at.
Private by design
There is no cloud button to press by accident, because there is no cloud.
Every question, answer and edit happens on your machine. Once set up, it works with the internet switched off entirely.
No sign-up, no email, no password. Install it and start.
No tracking, nothing reported back. The only things that ever leave are your licence check when you activate, and, if you choose a more powerful model, that one-time download. Your documents never leave your computer.
Inkwell works on your files in place. Every edit or new document is saved as a separate copy beside the original, never over it. Inkwell never overwrites or deletes, and every change can be undone.
Who it's for
If you have files on a computer, Inkwell is for you. Individuals, families, students, tradespeople, any business or workplace. It is your own AI, on your own machine, with no monthly bill.
Because nothing ever leaves the device, it fits especially well where documents are confidential, for example accountants, solicitors, GP surgeries and clinics, estate and letting agents, surveyors, recruiters, consultants, researchers and journalists. But you do not need a job title to want this. It is for anyone tired of paying £20 a month, forever, for software they will never own.
A third to charity
Getting started
Grab one file for your Mac or Windows PC. There is no account to create.
Open it like any other app. Inkwell gets everything ready for you, the AI model included.
Drop in the licence key from your email, and you are good to go.
No sign-up. No login. No technical know-how. You never configure a thing.
Questions
Your files never leave your computer, so there is nothing to upload and nothing for us to receive. Inkwell brings its own AI that runs entirely on your machine, with no cloud and no server in the middle. Because we never receive, store or process your documents, your client files, patient records, case files and accounts stay on your own device, under your control. Here is the simplest proof: switch the internet off once Inkwell is set up and it carries on working. How that fits your own data-protection obligations is for you to judge, as it would be with any software you run on your own computer.
Yes. One licence is one person, usable on two of their own computers. To kit out a team, buy several licences in one go using the "How many licences?" selector on the buy panel above, or adjust the number at the secure Stripe checkout. Each person gets their own key. No per-seat subscription, no annual renewal, just £99 for each licence, once.
No. Inkwell installs like any ordinary app and works the moment you open it. No server to set up, no account, nothing to configure. Point it at a folder of your files and start asking. It is built to be simple enough that nobody in the office needs to call anyone for help.
Yes. Updates are included at no extra cost, including smarter on-device models as they become available. You buy Inkwell once and it keeps getting better, with no subscription and nothing more to pay.
Yes. You can clear everything Inkwell has learned and start completely fresh whenever you like, from its settings. A reset wipes its memory and the list of documents you have shown it. Your real files are never touched, so nothing of your own is lost, only Inkwell's working memory of it.
Inkwell runs well on a typical computer from the last few years. 8GB of memory is plenty. On more modest or older computers, Inkwell automatically runs a lighter, faster model instead, so it still works without you needing a new machine. It right-sizes itself to your computer, and more memory than 8GB simply makes it quicker, not different. Everything runs on your own machine.
Inkwell runs on Apple Silicon Macs (M1 or newer) and on Windows 10 or 11 (64-bit). On the Mac you download a .dmg, on Windows a .exe, and one licence key works on both. Intel Macs are not supported for now. If you are unsure which Mac you have, click the Apple menu, choose About This Mac, and look for an Apple M chip.
It reads PDFs, Word (.docx, .doc), Excel (.xlsx, .xls), PowerPoint (.pptx), OpenDocument files (.odt, .ods, .odp), plain text (.txt), CSV (.csv), Markdown (.md), RTF (.rtf), web pages (.html) and saved emails (.eml and .msg). It also creates Word documents, Excel spreadsheets, PowerPoint presentations and PDFs from scratch, all on your own machine. It edits Word, Excel, PowerPoint, text and Markdown files. It always shows you what it plans to change first, and every edit or new document is saved as a separate copy, clearly marked "(Inkwell)", right beside the original in the same folder. The file you started with is never overwritten. PDFs are created, not edited.
Your licence works on two of your own computers at a time. If you replace a machine, you deactivate Inkwell on the old one and activate it on the new one, all with the same key. Moving to a new laptop costs nothing and needs no new purchase.
A third of our profit, after we cover costs, goes to UK-registered charities, distributed annually. It is the same promise that powers our Stamp app. Buying Inkwell gets you a tool you own outright and funds something good at the same time. We are a UK company, and our accounts are filed publicly at Companies House every year, so we are accountable on the public record, not just on our word.
