AI vs. simple automation: a practical rule of thumb

When a simple, rule-based approach wins, and when it doesn’t.

There are two common ways to reduce admin work:

  1. a simple, rule-based automation
  2. AI assistance for reading and writing text

Both can be useful, but for many workflows, the simple option is better.

Here’s the rule of thumb we use:

  • If the task has clear rules and the output must be consistent, start with a straightforward automation.
  • If the task needs judgement with language (summarizing, sorting, drafting), AI can help, with a quick review step.

Start with the simple, reliable option

Great candidates:

  • exporting PDFs
  • generating invoice numbers
  • sending templated emails
  • syncing data between Sheets and another system
  • creating files/folders with predictable names

These are repeatable, easy to check, and stable.

Add AI where it clearly helps

AI can help with:

  • turning messy notes into a clean first draft
  • summarizing long emails for internal handoffs
  • categorizing requests (e.g., “billing”, “schedule change”, “urgent”)

For internal tools, we prefer “smart” features that:

  • are optional (the core workflow still works without them)
  • include a review step before anything is sent or finalized
  • keep a clear record of what happened so issues are easy to trace

A sane middle path

Most useful systems combine both:

  1. rule-based automation for the “hard requirements”
  2. AI assistance for the parts that benefit from language understanding
