Who it is for
Media buyers and agencies managing paid campaigns across several ad platforms.
Overview
Markifact sits between ChatGPT and a marketing stack spanning Meta Ads, Google Ads, TikTok Ads, Google Sheets, Google Analytics, and, by the developer's count, twenty or more further platforms. Authenticated users can pull performance figures, build reports, set campaigns side by side, and examine trends.
It is not read-only. Optimizations can be prepared, campaigns created or updated, and approved actions run against live accounts from the same workspace. Those writes pass through Markifact's own permission and approval flow, so a change is reviewed before it goes out.
An existing Markifact account is needed. The app sells nothing inside ChatGPT and sends no one to a checkout or payment page.
Media buyers and agencies managing paid campaigns across several ad platforms.
It writes to live ad accounts, with approval flows standing between a request and a change.
Availability
Markifact is listed in the ChatGPT apps directory only. Optimization Up 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 Markifact'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 Optimization Up, 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.
