Start by logging your week before automating anything. Spend five days noting every repetitive task and roughly how long it takes. Then automate the one with the highest frequency-times-duration, not the one that's most annoying — those are usually different, and people reliably automate the annoying-but-rare task first and save nothing.
The tasks that automate well with current tools:
1. **Drafting repetitive written communication.** Status updates, standard replies, meeting follow-ups. Build a prompt template with your context and tone, paste in the specifics, edit the output. Saves most of the drafting time and all of the blank-page friction.
2. **Summarising documents and meetings.** Genuinely reliable, because it's grounded in text you provide rather than recalled. Meeting transcripts to action items is one of the highest-value uses available right now.
3. **Reformatting and restructuring data.** Messy text to a structured table, one format to another, extracting specific fields from unstructured documents. Very reliable and very common.
4. **First-pass analysis.** 'Here are 200 customer comments, group them by theme and give me counts.' Excellent as a starting point that you then verify.
5. **Research scaffolding.** Drafting an outline, generating the questions to investigate, producing a first structure you rewrite.
The approach that makes it stick:
- **Build reusable prompt templates rather than starting fresh each time.** Keep a document of prompts that worked, with placeholders. This is the difference between saving five minutes occasionally and saving hours every week, and almost nobody does it.
- **Include your context in the template** — your role, your audience, your style constraints, an example of a good output. Generic prompts produce output you have to rewrite entirely, which saves nothing.
- **Automate the draft, not the decision.** The reliable pattern is AI produces, you review and own. Anything that goes out without human review needs to be a task where errors are cheap.
- **Chain simple steps** rather than asking for one complex transformation. More reliable and easier to debug when it goes wrong.
What not to automate: anything requiring accountability or judgement about people, anything where a subtle error is expensive and hard to spot, and anything involving confidential data unless you're on an approved tool.
One warning worth taking seriously: measure whether you actually saved time. It's easy to spend forty minutes engineering a prompt for a task that took fifteen minutes and happens monthly. Automate what's frequent, and be honest about the payback period — the same discipline you'd apply to any other efficiency project.
