Inkblot Studio
Business software that runs on your own hardware.
A private AI workspace. On-screen guidance for any app you use. The till, the stock and the customer record a business runs on. Built as one line, so the ones you pick already know about each other.

For people
Apps for the person at the screen
One keeps your work on your own machine. The other makes any software easier to use than it was designed to be. Neither needs you to change how you already work.
Citron
ShippingYour private AI, running on your own hardware.
Anyone who cannot send their work to somebody else’s cloud — lawyers, accountants, clinicians, researchers, and the freelancers who sign the same confidentiality clauses.
macOS · Windows · Linux
Citron Guide
ShippingAsk how to do something. It points at the answer on screen.
The person who did not grow up with this. Parents and grandparents, staff on their first week, anyone handed software nobody had time to teach them — and the IT desk that fields the same question forty times.
macOS
For business
Software a business runs on
Sell, count what is left, and remember who bought it. Three tools over one ledger, so the till and the books never disagree about what happened.

Citron ERP
Private previewStock, invoicing and the books, without the spreadsheet in between.
Any business that holds stock and files returns — the owner who signs it off, the bookkeeper who closes the month, and the accountant who has to defend it.

Citron POS
Private previewTake payment anywhere, even with the internet down.
Anyone who takes payment face to face — the staff who touch it two hundred times a shift, and the manager who counts the drawer at the end of it.

Citron CRM
In buildOne customer record, and everything they ever bought.
Whoever owns the customer relationship — the front desk, the marketing lead, the owner who remembers regulars by name and wants the system to as well.

Who pays less
Learning on it, teaching on it, or just starting out — none of those should be the expensive case.
Students
Anyone enrolled full time, at any level.
A student email address or an enrolment letter, renewed each year.
Teachers and lecturers
Anyone who teaches, including part time and privately.
An institutional address, or a letter from the school.
Schools and universities
Whole-institution access for teaching and administration.
A named contact at the institution.
Non-profits and charities
Registered organisations, and the volunteers who run them.
A registration number.
New businesses
A first venue in its first year of trading.
A company registration dated inside twelve months.
Paid yearly
Anyone who would rather not think about it every month.
Nothing to prove — it is simply cheaper.
Rates are being set now and will be published before anyone is asked to pay. If you want to be told when they are, leave us a line.
Where it stands
What we have built so far.
Offline-first by default
The POS keeps taking orders when the network drops and reconciles when it returns. Guidance answers most questions without a model at all, and the AI workspace runs on your own machine.
One ledger, not five integrations
Recipes deplete stock as orders land. Journals post themselves. The guest record the POS writes is the record the CRM reads. Nothing is synced between products because nothing is separate.
Built for Bulgarian requirements
Fiscal device drivers, VAT ledgers and the Дневник продажби report are part of the ERP rather than an afterthought, because compliance is not a plugin.
One design system across the line
Every product is drawn from the same tokens, type and motion. They look related because they are, and a person who learns one already knows where things are in the next.
