Marvyn

ChatGPT plugin

Your marketing, analysed

View in ChatGPT directory

Marvyn is a marketing analytics tool for businesses. It reads the marketing data you have connected to your Marvyn workspace and answers questions about it with numbers Marvyn has already calculated.

What you can ask: how your marketing is doing overall; which ad campaigns and ads are working or wasting money (Meta, Google, LinkedIn, Snapchat and Reddit ads); where your website funnel loses people; whether your conversion tracking can be trusted; why a number changed; and what to fix first.

Data sources: ad accounts, website analytics (GA4), Google Search Console, Facebook and Instagram, and Shopify.

Reliability: every answer says how fresh the data is, which sources are missing, and which figures were withheld because there was not enough data behind them. Marvyn says "not enough data" rather than guessing.

Without an account: check whether AI crawlers can read any website (robots.txt rules for AI crawlers, llms.txt, sitemap and home page).

Who it is for: founders, marketers and agencies who use Marvyn (marvyn.io). Connecting uses your existing Marvyn account, and available features follow your Marvyn plan.

Limitations: read-only. Marvyn cannot change, pause, publish or spend anything, and reads only the one Marvyn workspace you connect.
