AD-HOC

The Ad-Hoc Problem

Most people’s “AI workflow” looks like this: open ChatGPT, type a question, copy the answer, paste it somewhere, close the tab. Repeat 30 times a day.

That’s not a workflow. That’s just using a calculator one equation at a time.

The teams winning in 2027 aren’t using more AI tools — they’re using AI tools that hand off to each other, remember context, and trigger downstream actions automatically. That’s what tool stacking means.

"Productivity is never an accident. It is always the result of a commitment to excellence, intelligent planning, and focused effort."
Paul J. Meyer, Attitude Is Everything

A well-designed AI stack doesn’t just save hours. It creates outputs that compound — where the work done today automatically seeds tomorrow’s work.

WHAT

What Is AI Tool Stacking?

AI tool stacking is the deliberate design of a workflow where multiple AI-powered tools:
The difference between ad-hoc AI usage and a stack:
Ad-Hoc Tool Stack
Copy-paste between tools manually Automatic handoffs via Zapier/n8n
Re-explain context every session Shared context stored in Notion/ClickUp
One task at a time Parallel pipelines running in background
Output stays in one tool Output published to 3 channels automatically

Capture, Process, Create, Publish

Before choosing any tool, draw your workflow. Every knowledge or content workflow has four stages:

Here’s an example for a content team:

The moment you can draw this diagram for your work, you’re ready to automate it.
HUB TOOL

Choosing Your Hub Tool

Your hub is where work lives, context is stored, and where other tools connect. Get this wrong and the stack falls apart.
Notion AI
is ideal for knowledge-rich teams — writers, researchers, product teams. It excels at storing structured and unstructured content together, with AI that can query across your entire workspace. If your work is document-heavy and non-linear, Notion is your hub.
ClickUp
suits teams with project-based workflows — agencies, dev teams, ops. Its AI handles task generation, status summarisation, and project briefs. Better than Notion for tracking work states and deadlines.
Asana
is strongest for structured, repeatable project workflows with clear owners. Its AI Assistant can generate project plans from descriptions, identify at-risk tasks, and draft status updates.
My recommendation for most teams:
Notion AI as the knowledge hub, ClickUp or Asana as the task/project layer. They play well together.
CONNECTING
Connecting Tools

Zapier vs n8n

This is the plumbing of your stack. Every tool handoff that isn’t automated is a tax on your attention.
Zapier
is the accessible choice. 7,000+ integrations, no code required, multi-step Zaps with AI steps built in. If you can describe the automation in plain English, you can probably build it in Zapier in 20 minutes. The limit: complex logic (branching, loops, error handling) gets expensive and unwieldy.
n8n
is the developer’s choice. Open source, self-hostable, full JavaScript execution in workflow steps, native AI agent nodes (including direct LLM API calls). Far more powerful for complex workflows; requires comfort with a visual node editor.
SPRAWL
End-to-End Pipeline

Avoiding Tool Sprawl

This section exists because most teams get this wrong.

Tool sprawl is when you have 12 AI subscriptions, they all do slightly different things, nobody knows which one to use, and $800/month is being burned on overlapping capabilities.

Signs you have tool sprawl

The fix
a stack audit every 90 days

For each tool:
1. Used by ≥2 team members weekly? (If no → cut)
2. Has a specific, documented role in the workflow? (If no → cut)
3. Is its function covered by a tool we already pay for? (If yes → cut)
4. Does it connect to the hub (Notion/ClickUp)? (If no → evaluate)
A focused stack of 5–7 well-connected tools beats a sprawling suite of 15 disconnected ones every time.

Frequently Asked Questions

No. Zapier and Make.com (formerly Integromat) let you build powerful automations without code. Claude's Projects feature also lets you create persistent, connected AI workflows through a UI. Coding (n8n, custom scripts) unlocks more power but isn't required to get significant ROI.

A solid individual stack runs $50–150/month. A team stack (5–10 people) typically runs $300–800/month, depending on usage. The ROI calculation is straightforward: if it saves 10 hours/month at $50/hour, that's $500/month in labour saved at $100–200 in tool costs.

Notion AI wins for teams (collaboration, databases, sharing). Obsidian + AI plugins (Copilot plugin, local LLM via Ollama) wins for individuals who value data ownership, offline access, and cost control. For portfolio or business use, Notion AI's team features are the practical choice.

Start with Zapier. Build your first 3 automations. If you hit its limits (complex branching, custom code, volume costs), migrate to n8n. Most teams never need to.

Create a "brand voice" document and include it as context in every Claude API call. A 300-word document describing your tone, vocabulary, audience, and writing patterns will dramatically improve output consistency. Store it in Notion and inject it via a system prompt in your n8n/Zapier AI steps.
