Use Financial Freedom in your AI

Install one skill in Claude, ChatGPT or Grok, then ask your question in plain words. Your AI looks up what you did not say, lists every assumption with its source, and replies with one link that opens Financial Freedom on your scenario. The tool works out the answer, so the figures you see are the tool's, not the chatbot's.

A .zip skill: SKILL.md (how to answer), references/ (every input, its range and the Quick Starts) and scripts/build_link.py (builds and checks the link). Read SKILL.md

Install the skill

Pick your assistant. The demo plays the steps; press a step to jump to it.

    Menus move as these apps update; look for Skills in Settings. Skills need the app's code tool switched on (Claude: Code execution and file creation). No skill support on your plan? Attach brotools-financialfreedom.zip or SKILL.md to the chat and say "use this skill".

    How to use it

    Ask as you would ask a friend. With the skill on, the AI keeps your figures, researches the rest, and hands you the link. It does not give the answer itself: the tool does, once you open the link.

    I'm 35 in Perth, I have $180k invested and save $3,000 a month; when can I retire?

    Using skill brotools-financialfreedom Ran scripts/build_link.py: link checked

    Your inputs

    • Age now: 35 yrs
    • Invested assets today: $180,000
    • savings: $3,000
    • savingsPeriod: a month

    Assumptions

    1. Living expenses: 60,000 a year, a round figure for one person in Perth since the user did not say what they spend. It replaces the Moderate FIRE Quick Start's 65,000.
    2. Savings: the 3,000 a month is an amount put aside, not pay, growing 3% a year as in the Quick Start.
    3. Returns: the 180,000 invested earns 8.5% a year with 15% volatility (the global diversified share preset), before inflation and after fees.
    4. From the Quick Start: life expectancy 90, inflation 2.5% a year, spending of 100% of living expenses once work stops, and the goal Just Die, with no stages and no pension. The retirement age is left for the tool to find.

    Open this scenario
    • Your figures stay yours. Anything you state goes in as you said it; correct any assumption and the AI sends a new link.
    • Checked before you see it. The skill's script checks every input's name, range and choices before the AI sends the link, so it opens the scenario listed.
    • The tool shows what the AI chose. When the link opens, a banner lists each value the AI set and why, with an Undo back to your own inputs.
