I build tools the same way I approach product work: find a real problem, strip it to its core, and ship something useful. These are free, browser-based, and built without a team or a budget. No logins. No servers. No catch.
Built overnight after my daughter was born. I wanted to know exactly how much her savings could grow if I started early. One Google search led to another and nothing covered 30 countries with real inflation rates. So I built it. Covers 6 continents, multiple investment vehicles, and projects growth all the way to age 30 in today's money.
Most tax tools are either too simple to be useful or too complex to navigate without an accountant. TaxClarity walks through the key lines of IRS Form 1040 in plain language (income, deductions, credits) and tells you what you likely owe or get back. Free, private, and runs entirely in your browser.
Treasurers for student and community groups spend hours formatting spreadsheets into presentable reports. This tool does it in minutes. Enter income and expenditure, get a clean report with charts, budget vs actual tracking, quarterly breakdown, and a shareable link members can open without downloading anything.
