Readers, writers, and students who want dictionary style detail without switching to a separate reference site.

Overview
A-Z Dictionary is a lookup app from Widget. Given a word or a phrase, it returns the meaning along with supporting detail: how the term is used, sample sentences, where it came from, and words that are close in meaning or opposite to it.
It is triggered by asking ChatGPT to define something once the app is connected. The developer's example prompt is a two word instruction to define AI, which points to short, direct queries rather than long descriptions of what is wanted.
The record covers definitions and related vocabulary only. Nothing in it describes saved word lists, quizzes, or translation into other languages.
Readers, writers, and students who want dictionary style detail without switching to a separate reference site.
It returns word history and opposites alongside the plain definition, not just the meaning by itself.
Availability
A-Z Dictionary is listed in the ChatGPT apps directory only. Widget 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 A-Z Dictionary'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 Widget, 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.
