NestPilot Foundation is a 501(c)(3) public charity offering anonymous educational retirement calculations in ChatGPT. Users can compare retirement ages, Social Security claiming ages, Roth conversion scenarios, Medicare enrollment timing, and a full retirement forecast without creating an account or providing an email address. Model-visible launchers only open interactive review UIs and never calculate. The optional NestPilot Retirement Checkup skill opens one persistent widget that displays supplied facts and defaults, requires an explicit baseline button click, and then offers one relevant follow-up at a time behind its own button. Every completed result remains available as a tab. Forecast and analysis tools are app-only, anonymous, and do not save plans or create records. If the user explicitly clicks Continue in web planner, an app-private helper creates a temporary 24-hour, single-use handoff containing the complete plan input so nothing must be re-entered. The app does not sell products, promote paid services, manage investments, compare or enroll users in Medicare plans, prepare tax returns, diagnose medical conditions, collect credentials, or execute transactions.
