Social Media Content Engine

Content ships on a schedule, with a human in the loop to review and post — a nightly pipeline that reviews what's already been said, plans tomorrow, and drafts it.

the gap

A content calendar dies the week it's made.

Planning a month of posts in one sitting feels productive right up until week two, when there's no time left to actually write anything, and the calendar just becomes a list of things that didn't happen. Posting consistently needs something that plans and drafts every single day, not a burst of intention once a month.

how it runs

Every night, the same discipline.

Review

Recent posts and prior analysis are pulled first, so tomorrow's plan doesn't repeat what's already been said.

Plan

Tomorrow's content is planned and turned into a generation prompt — copy and a visual concept, not just a topic.

Draft

The prompt is sent out, generated, and parsed into a usable draft — caption and image prompt both ready to review.

Queue

The draft lands in the content queue, with a nightly heads-up and a weekly batch summary posted to Slack.

the architecture

One pipeline, 4 stages.

04 Queue Stored and posted as a heads-up to Slack.

proof of work — the pipeline

The n8n canvas, in full.

n8n workflow canvas: a nightly schedule fetching recent posts and analysis, planning tomorrow's content, generating and parsing it, storing it in a content queue, and posting nightly and weekly summaries to Slack. — Nightly: review recent posts, plan tomorrow, generate and parse the draft, store it in the queue, and post a heads-up to Slack. A separate Sunday run batches the week ahead.

proof of work — sample output

What lands in Slack.

Slack message from Web3 Dashboard Bot: this week's content plan, listing planned post copy for upcoming dates alongside full visual generation prompts for each post. — The week's plan, drafted end to end — post copy and a full visual prompt for each one, ready to hand straight to image generation.

proof of work — a generated post

From prompt to asset.

Generated Digital Renaissance style image: a towering stack of stone blocks under a shaft of light, dwarfing three smaller stacks beside it, with mechanical gear-arms working on the tallest stack. — The "towering stack of building blocks" prompt from the plan above, generated and ready to post.
