THE PRODUCTS
One platform. Three products cut from it.
Everything here came out of our studio and is ready to deploy. Key4 is the platform: our method for making small language models expert and checking them, our engineering that runs them on ordinary hardware, the phone included, and our own small language model at its heart. Key4MB, Key4KB and Key4EDU are built on it. The range will grow.

KEY4 · THE PLATFORM
The platform they are built on.
Key4 is the holding platform everything we make is nourished from: our method for making small models expert at a job and checking them against answers that can be verified; our engineering that makes them run on ordinary hardware, from an office server to a phone; and, at its heart, our own small language model. It is both platform and product. Fitted to one job on your records, it runs on a machine you already own.
- WHO IT IS FOR
Any organisation with one job that must be done well, inside its walls, and checked before it is relied on.
- STATUS
Ready to deploy.
KEY4MB · THE FLAGSHIP
An AI that uses your phone the way you do.
The whole small language model sits inside the phone. It works in every app, shows every step, and nothing it reads ever leaves the device. Zero tokens. Zero cloud. Zero data leaving your phone. A platform in its own right: partners build on it.
- WHO IT IS FOR
Phone makers, carriers and retailers, enterprises and institutions, chipmakers and integrators.
- STATUS
Ready to deploy. Open to partners.
- BUILT ON
The Key4 platform: our method and engineering, on models fitted by us for the phone.
KEY4KB · KNOWLEDGE BASE
Every answer, with its page.
Your scanned orders, circulars and files, made searchable by meaning, across languages and scripts. Ask in your own words; the answer quotes the document, shows the page, and is checked word for word. It changes a records office from a room people search into a colleague that answers.
- WHO IT IS FOR
Government departments and secretariats, cooperative banks and societies, universities and boards, legal cells and courts, and any compliance team that answers from its files.
- STATUS
Ready to deploy.
- BUILT ON
The Key4 platform: our method and engineering, on open-weight models used under their licence.
KEY4EDU · ADAPTIVE LEARNING
It teaches by asking.
Key4EDU, our learning product, built on Key4. It knows the learner, teaches by asking rather than telling, and shows the teacher the whole class. It changes what a classroom can know about itself.
- WHO IT IS FOR
A learner preparing for an examination, a learner who is struggling and needs to be seen, and a teacher with a full classroom.
- STATUS
Ready to deploy.
- BUILT ON
The Key4 platform. Its tutor runs on the Key4 model itself, so its explanations are checked rather than trusted.
Made once for many; fitted, for you.
A product shortens the work for everyone who picks it up; our services fit it to your organisation and run it for as long as you rely on it. A product is chosen only when it is the right answer, and the fitting is yours.
Our AI skill makes both: the transformations we run for you, and the products we build.
The studioOWNERSHIP OF THE MODEL, THE TEST AND THE RECORD
No lock. Just the key.
Nothing we build ties you to us. You hold the model, the test and the record, and you can run them without us.
Let intelligence grow with trust, and all of us rise with it.
