Field calculators for IT infrastructure conversations. Live at calc.nixfred.com.

What this is

Interactive decision tools built for live customer meetings, not for spreadsheets. Renewal triage, POC readiness, rough sizing, AI application readiness, and whatever the field demands next.

Live now: TokenOps, an AI workload placement and token economics calculator. Transparent math throughout: every number shows its formula, variables, live substitution, assumptions, and sources. Methodology in docs/tokenops.md, completion audit in docs/tokenops-audit.md, regression harness in tests/.

Every calculator returns four things:

1. A customer friendly answer.
2. A whiteboard card.
3. A conversation script.
4. A next action.

The rules these tools follow

1. Rough math is never presented as a quote.
2. No vendor pricing is hardcoded. You enter your own assumptions.
3. Every assumption is visible on the result.
4. No logins. No saved data. Everything calculates in your browser.

Why open source

The formulas are the product. Anyone using a calculator in a meeting should be able to open the source and check the math, and anyone who finds better math is welcome to send a pull request. Each live calculator gets a methodology document in docs/ explaining its logic and its limits.
