Are the tools really free?
Yes. All tools on ZNICE are free to use with no account required. There are no premium tiers, no paywalls, and no usage limits. The site is sustained by the paid services listed on the Services page.
Do the tools save my data?
No. All tool state is held in the browser only. Nothing is sent to a server. When you navigate away or close the tab, the inputs reset. This is intentional — these are thinking aids, not saved documents. If you want to preserve a result, copy and paste it into your own notes.
How accurate are the calculators?
The calculators use standard formulas with the inputs you provide. They are as accurate as your inputs. The Rate Calculator calculates a minimum viable rate based on the income target and hours you enter — it does not factor in variables you do not provide, such as local tax complexity or pension contributions. Treat the outputs as a starting point, not a definitive answer.
Can I use ZNICE tools for client work?
Yes. There are no restrictions on how you use the outputs from ZNICE tools. If the Decision Matrix or Project Filter helps you structure a client recommendation, use it.
Why does the tool output reset when I navigate back?
By design. ZNICE does not persist your inputs between sessions. The tools are for in-the-moment structured thinking, not ongoing project tracking. If you need to return to a calculation, keep the tab open or note down your inputs and key outputs.
What is a Decision Brief?
A Decision Brief is the format used for each tool in the Tools section. It follows a four-step structure: Context, Criteria, Weight, Output. You provide the inputs at each step — the tool organises them and produces a structured result. The structure is the same across all tools; the specific inputs vary.
How is ZNICE different from a productivity app?
ZNICE does not manage your tasks, track your time, or organise your projects. It is not a workspace or a second brain. It is a set of decision instruments — you come here when you are facing a specific decision and you need a structured way to think through it. That is the scope.
Can I suggest a new tool or framework?
Yes. Use the contact page and select "Tool suggestion". Describe the decision type, who faces it, and what a structured instrument might look like. Not all suggestions will be built, but they inform what gets prioritised.
Is ZNICE available in other languages?
Currently English only. There is no active translation planned.
