Generate & Schedule AI Reddit Discussion Posts with GPT-4 & Airtable

This n8n workflow automates the creation and posting of engaging discussion questions to Reddit subreddits using AI. It starts with a Schedule Trigger that runs at set intervals, fetches previously posted questions from an Airtable database, aggregates them, and feeds them into GPT-4 (or similar model) to generate fresh, non-duplicate content tailored to your subreddit's theme.

The generated question is then posted directly to Reddit as text, image, or link post via the Reddit node. Finally, the new post is archived back to Airtable for future reference, ensuring no repeats. Setup is quick with a pre-made Airtable template, requiring only API tokens and basic configurations.

Benefits include consistent community engagement without manual effort, time savings for subreddit moderators or marketers, and scalable content creation. Ideal for growing online communities, brand promotion, or niche discussions on AI, tech, or any topic.

Use cases: Reddit mods maintaining activity, marketing teams driving traffic, or anyone needing automated social proof through discussions. Handles post types flexibly and supports customization via system prompts.
