Our work/N8N / AI AUTOMATION

Personal Brand AI Engine

An AI content and publishing workflow built around editorial memory, AI content generation, image generation, scheduling, a same-day guard, LinkedIn publishing and content history. It runs in your own n8n instance rather than behind someone else's SaaS.

Case/FROM PROBLEM TO STATUS

Live
01Problem
Producing regular content that does not repeat itself, preparing a visual for it and publishing on time takes hours every week — and automations built on a single prompt soon start repeating themselves.
02Approach
The work is split into separate stages: idea, platform formatting, visual direction, image generation, branding, publishing and recording. History is read before generation and used as context; the expensive steps run only after the same-day guard.
03Solution built
An n8n workflow, scheduled on a weekly calendar or started by hand, that publishes a LinkedIn post with an image and records every publication in its content history.
04Technologies used
  • n8n
  • OpenAI (text and image)
  • LinkedIn API
  • n8n Data Table
  • Private branding service (production version only)
05Current status
Live. The public template is on GitHub; the personal production version is in use on the founder's LinkedIn account.

Template and production version

Public template
The workflow published on GitHub, with credentials and personal identifiers removed. It does not include the branding service; setup and configuration are the user's own. The repository carries no software licence.
Personal production version
The version running on BaysSystems' own n8n installation for the founder's personal LinkedIn account. Unlike the template, it uses the private branding service. It is not publicly available.

Most AI content automations are a prompt on a timer. They post confidently, repeat themselves within a fortnight, and have no idea what they already said.

The problem

A publishing workflow that cannot remember is not an assistant, it is a generator. Without an editorial memory it re-treads the same three ideas; without a same-day guard it double-posts; without persistence it starts from zero on every run. The hard part of automated publishing is not generating text — it is everything around the generation step.

What it does

  • Reads its own publishing history before it writes anything new
  • Passes recent topics and angles to the AI and instructs it not to revisit them
  • Refuses to publish twice in the same day, by design rather than by luck
  • Generates the post, formats it for LinkedIn, and derives a visual direction from the content itself
  • Generates an image and publishes through the LinkedIn API (branding is applied by a private renderer in the production version)
  • Writes the result back to history so the next run knows it happened

System/EXECUTION PATH

How the run happens.

Read before written, guarded before generated, persisted after published. The expensive steps never run for output that would be rejected anyway.

Pipeline

00 / 11 STAGES

  1. Recall

    1. Schedule / Manual Trigger

      Scheduled run, or fired by hand.

    2. Content History

      Prior output is loaded before anything is written.

    3. Editorial Memory

      History becomes working context for this run.

    4. Same-Day Guard

      Fails closed if today has already been published.

  2. Generate

    1. AI Content

      The post is generated against editorial memory.

    2. Platform Formatting

      Shaped for LinkedIn, the platform it publishes to.

  3. Compose

    1. Visual Direction

      An image brief is derived from the content itself.

    2. Image Generation

      The brief drives generation, not a random prompt.

    3. Brand Renderer

      Output is composed into a consistent branded frame.

  4. Publish

    1. LinkedIn API

      Published through the platform API.

    2. History Persistence

      The run is written back. The loop closes.

System architecture

The workflow is built as a linear pipeline with explicit state at both ends: history is read before generation and written after publication. Guards sit between recall and generation so the expensive steps never run for output that would be rejected anyway. Each stage is a discrete n8n node boundary, which is what makes a swap — a different model, a different image generator — a change at one boundary rather than a rewrite. The published workflow publishes to LinkedIn; other destinations are an extension point, not something it does today.

Current scope. The published workflow publishes to LinkedIn. Its stage boundaries are designed so another destination can be added, but that is extensibility rather than current behaviour — nothing here claims multi-platform publishing today.

Capabilities

What the system actually holds.

  • 01

    Editorial memory

    Published content is persisted and read back as context on every run. The workflow's knowledge of itself is durable state, not something reconstructed from a prompt each time.

  • 02

    Anti-repetition instruction

    Recent topics, angles and categories are given to the AI as context, with an explicit instruction not to revisit them in different words. This is an instruction to the model; no separate similarity measurement is performed.

  • 03

    Same-day guard

    An explicit gate prevents a second publish inside the same day. Scheduling mistakes and manual re-runs fail closed rather than producing duplicate posts.

  • 04

    Content and visual generation

    Copy is generated, formatted for LinkedIn, and given a visual direction derived from the content — which then drives image generation rather than a random illustration.

  • 05

    Automated branding

    In the production version, a private brand renderer composes the generated image into a consistent branded output. The renderer is not part of the public template.

  • 06

    History persistence

    Every completed run is written back to the content history. The loop closes, and the next run is better informed than the last.

Who it is for

  • Operators and founders who publish consistently and want the pipeline to hold the editorial memory instead of their head

  • Technical teams who would rather own the workflow in their own n8n instance than rent it from a SaaS

  • Engineers who want a real reference architecture for an AI pipeline with memory, guards and persistence — not a demo prompt chain

What you need to run it

  • n8n (self-hosted or cloud)
  • An LLM provider of your choice
  • An image generation provider
  • LinkedIn API credentials
  • A persistence target for content history

Credentials and provider accounts stay yours. Nothing routes through BaysSystems infrastructure.
