Most software shows you data and leaves you to work it out. We build the opposite: tools that read your situation and tell you what to do next. One tool per problem — no suites, no bloat.
The tools
Every Sellay tool stands on its own, with its own identity and its own colour. None of them tries to do everything — that is the whole point.
Your personal finance coach
Not a budgeting app. A coach that tells you whether you are on track, how much you can safely spend this month, and how to reach your goals faster. Available in five languages.
In design
The same method applied to another everyday problem. We would rather ship one tool properly than five half-finished ones.
How we build
Charts describe the past. Our tools take a position: here is your situation, here is what to do about it today.
No forced bank connection, no resale to third parties, no advertising trackers. You enter what you want, when you want.
No empty screen on day one. Every tool is usable and personalised before you have finished setting it up.
We publish tools we intend to maintain for years. No feature is added just to fill a comparison table.
Free to start, no card required. Your plan is ready in under two minutes.
