We built a free n8n workflow validator after AI kept writing workflows that wouldn't import

Hi makers 👋 We launched Gydmation AI here last week, and one lesson surprised us: AI-written n8n workflows fail for the same few reasons almost every time. Nodes that don't exist, settings from the wrong node version, guessed IDs, broken connections, expressions missing "=".

So we made the checker behind Gydmation a free page. Paste any n8n JSON and it shows what's wrong, fixes the safe mistakes, and draws the workflow. It runs in your browser with no sign-up:

The same page has a live demo of Gydmation itself: describe an automation in one sentence and it builds, validates and deploys the n8n workflow to your own n8n.

Question for anyone using AI to build automations: do you check the output before running it, or just test and fix?
