Seven calculators for US equity compensation decisions
Overview
OptionsAhoy is a set of seven calculators for people holding US equity compensation. They cover ISO exercise scheduling against AMT, sell versus hold decisions for both NSOs and RSUs, QSBS qualification, concentration risk in a single stock, the cost of a protective put, and how much equity to sell in order to reach a target cash amount.
The calculations are deterministic and run against the federal tax code together with all fifty states and the District of Columbia, so the output is a computed number rather than an approximation.
AlphaLatitude lists the app as free with no account required. It is described as a planning calculator and not as tax advice.

State-by-state coverage sitting on top of the federal rules is what separates it from a generic equity calculator.
Availability
OptionsAhoy is listed in the ChatGPT apps directory only. AlphaLatitude Inc. has no connector under the same domain in the Claude directory; 392 of the 3,150 products here are on both marketplaces, and this is not one of them.
ChatGPT apps are built on MCP, and the same server can back a Claude connector, so the absence is a distribution decision rather than a technical one.

This is an independent catalogue entry compiled by Node8 from OptionsAhoy's public marketplace listing as it stood in August 2026. Listing facts come from the marketplaces; the comparisons against the rest of the directory and any live-endpoint measurements are Node8's. Node8 is not affiliated with AlphaLatitude Inc., and inclusion here is not an endorsement.
Node8 builds MCP servers end to end: deciding which tools are worth exposing, the authentication and permission model, the review submissions, and the onboarding that gets them used. One server serves ChatGPT, Claude, and Microsoft Copilot.
