Retired Tools

Retired Tools

A small library of interactive pages at /tools. Each tool does one thing — converts, calculates, answers a specific numeric question — and gets out of the way. No sign-in required, no tracking, no notifications.

Tools are different from the blog on purpose:

• Blog posts explain a topic end-to-end. Long-form reading.
• Tools give you a number, a rate, or an answer. Short-form use.

You can have the same subject covered in both places — a blog post about patience and a tool that calculates it — and the two link to each other.

How to use a tool

Open /tools, pick one from the grid, and it loads. Every tool is one page: the widget sits at the top, an explainer below, and a short FAQ at the bottom for edge cases.

All tools work on your phone or desktop. Inputs are keyboard-friendly (Tab to move between fields, Enter to calculate). Nothing you type leaves your device unless the tool specifically calls a price API (e.g. a live crypto converter).

Filtering

The /tools index has topic filters at the top — tap a pill to narrow down. The same tool can appear under multiple topics. Tap All to clear.

Sharing a tool

Every tool has its own short URL like /tools/<slug>. Copy the URL bar to share the exact thing.

What's here right now

• How long to save to buy it outright — the patience calculator. Pick a target (Bitcoin, a Porsche, a small house, or a custom number), pick what you can save per month, see when you'd own it with no loan and no interest paid.

More on the way.

What's not here

• No user accounts on tools themselves. Nothing is saved server-side; every number you type disappears when you close the tab.
• No embeds. You can't drop a Retired tool into another site yet. If that becomes useful, we'll add it.
• No RSS for tools. The blog has one; tools are interactive references, not serialized content.

For tool ideas

If there's a specific calculation or conversion you'd use regularly and it isn't here, let us know. The bar for a new tool is simple: it answers a clear numerical question, it works in a few seconds, and it doesn't need to be a 1,500-word article.
