Who’s it for

Marketers, creators, and social managers who want hands-off reposting of a specific X (Twitter) user’s videos — with on-brand AI captions and clean, deduplicated logs.

What it does / How it works

On a schedule, the workflow resolves a target user, fetches recent tweets with media, filters to video posts, and writes them to Google Sheets for tracking and dedupe. It then builds a shareable video URL, generates a short caption via an AI model (OpenRouter), posts to your X account, and updates the sheet with completion status. Sticky notes inside the workflow explain each step, setup tasks, and best practices.

How to set up

Add credentials: Twitter (X) OAuth2, Google Sheets OAuth2, OpenRouter.

Replace the demo Google Sheet with your own (document ID & sheet name).

Set the target X username (or parameterize it).
