About
Who builds these, and why they are free
Scult Tools is built and maintained by Scult, an AI-first digital agency based in Noida, Delhi NCR. We build websites, apps, custom software and AI agents for a living.
These are our own tools
Every tool here started as something we needed on a client project — an invoice that had to reconcile to the paisa, schema markup that had to validate on the first try, a favicon set that did not need anyone's upload server. We built them properly, so we published them.
That is also why they behave the way they do. There is no signup because we never wanted one. 13 of 15 run entirely in your browser because uploading a file to process it was always the slower option. And every calculator shows its formula because we wanted to be able to check the numbers ourselves.
The prompt library is held to the same standard: 254 free prompts for ChatGPT, Claude, Cursor, Midjourney and the rest, each published with an explanation of why it works and the tool version it was verified against — dated, so you can judge how current it still is.
The business model, stated plainly
Most of these tools cost us nothing to run, so there is nothing to recover. We publish them because when you eventually need a team rather than a tool, we would like you to already know who we are. That is the whole arrangement — no trial that expires, no feature held back, no email wall in front of a result.
Corrections welcome
Every tool states its limitations on its own page, because a tool that pretends to be more certain than it is will eventually mislead someone. If you find a calculation we have got wrong, we would genuinely rather hear it — the contact details are on scult.in.
