Tools we built because we needed them

Calculators from our own work, left open for everyone. Everything runs in your browser: no account, no email, nothing sent to a server.

Cyprus tax and payroll

We run a company in Paphos, so we do this maths anyway. Rates are checked against PwC, KPMG and the Tax Department, and every tool can be embedded on your own site.

AI and local models

Built for our own AI work and left open. No account, no email, nothing sent to a server.

Hardware

Local LLM hardware calculator

Pick your GPU, Mac or VRAM budget and what you want the model to do, documents and scans included. It lists the open models that fit, at which quantisation, with how much context, roughly how fast, and says why the ones that do not fit, do not.

Cost

Self-hosted vs API cost calculator

Your monthly token volume against hardware, electricity and ops. Gives the monthly cost each way, the volume where the two lines cross, and how long the hardware takes to pay for itself.

Behind the tools is the day job
