Think, Write, and Brainstorm Better

AI is an extraordinary writing partner. It can draft emails, structure arguments, brainstorm ideas, rewrite clumsy sentences, summarise long documents, and help you think through problems.

You are not replacing your own thinking. You are giving yourself a sounding board that is available 24 hours a day and never gets tired of your questions.

Which AI Tool for Writing

The Google Ecosystem Advantage

If you use Gmail, Google Docs, and Google Drive daily, Gemini is worth trying alongside Claude or ChatGPT. Google AI Pro (US$20/month, ~A$32) gives you Gemini embedded in all your Google apps, plus upgraded NotebookLM with 5x more audio overviews and enhanced features. No other AI tool has this level of integration with Google's suite. However, the Gemini integration in Workspace apps requires the paid tier.

Power Features That Change Your Workflow

Claude Projects

Once you start using Claude regularly, Projects will change how you work. A Project is a persistent workspace where you can upload reference files (documents, spreadsheets, images), write custom instructions that apply to every conversation in that project, and have multiple chat sessions that all share the same context.

Why this matters: without Projects, every new conversation starts from scratch. With Projects, Claude already knows your background, your preferences, your reference material, and your specific requirements. I use Projects for everything from book writing (where Claude has the full manuscript and style guide) to job applications (where it has my resume and target role descriptions). The difference in output quality is dramatic.

Projects are available on the free tier with limitations, and fully on Claude Pro. If you use Claude for any ongoing piece of work, set up a Project for it.

Claude Cowork

Cowork is Claude's newest and most ambitious feature. It turns Claude from a chat assistant into something closer to an actual digital coworker. You point it at a folder on your computer, give it a task, and it gets to work: reading files, creating documents, organising content, extracting data, and completing multi-step workflows without you guiding every action.

Think of the difference this way: regular Claude shows you how to do something. Cowork does it. Need to sort a chaotic downloads folder? Compile expense data from a pile of receipts? Pull key dates and obligations from a stack of contracts? Cowork handles it.

It also connects to external tools like Gmail, Google Drive, and Slack, meaning it can pull information from your real work environment, not just files you manually upload. The Dispatch feature lets you control Cowork from your phone while the desktop app runs, so you can delegate tasks while you are away from your computer.

Cowork is available on Pro and Max plans. It is still in research preview, which means it is powerful but has rough edges. Complex spreadsheets can confuse it, and some tasks run slower than you would expect. But the trajectory is clear: this is where AI assistants are heading.

Persistent Instructions and Memory

This is one of the most underused features across all the major AI tools, and one of the most transformative once you set it up.

Both Claude and ChatGPT allow you to provide standing instructions that apply to every conversation, not just one. You tell the tool who you are, how you like to work, and how you want it to respond, and it remembers this across every new chat.

Claude has two mechanisms. First, user preferences (found in Settings) where you can write instructions about your preferred tone, formatting, and how you want Claude to behave. Second, memory: Claude learns from your conversations over time and builds up knowledge about you, your name, your work, your preferences, your ongoing projects, that it draws on in future chats. You can view, edit, and delete what Claude remembers. You can also explicitly tell Claude to remember something: "Remember that I work in IT procurement and I prefer concise responses with no jargon."

ChatGPT has a similar setup. Custom Instructions (found in Settings > Personalization) lets you provide two blocks of text: one describing who you are and what you do, and another describing how you want ChatGPT to respond. Memory works automatically. ChatGPT picks up facts from your conversations and stores them for future reference. You can review and manage what it has stored in Settings > Personalization > Memory.

Gemini has memory capabilities as well. It learns preferences from your conversations and, on paid plans, integrates with your Google account context (your emails, calendar, documents) to provide more personalised responses.

Why this matters: Without persistent instructions, every new conversation starts from zero. The AI does not know your name, your role, your industry, or your preferences. You end up repeating the same context every time. With instructions and memory set up, the AI already knows that you are an IT professional based in Melbourne who prefers direct communication and works in procurement risk. The quality and relevance of every response improves immediately.

What to put in your instructions: Your name and location. Your profession and industry. Your communication preferences (concise vs detailed, formal vs casual). Any recurring context ("I frequently ask about Australian law," "I work with government procurement," "I prefer metric units"). Formatting preferences ("Use short paragraphs," "Avoid bullet points unless I ask for them," "Never use emojis"). The more specific you are, the better the results.

Open Claude or ChatGPT settings. Find the preferences or custom instructions section. Write 3-5 sentences about who you are and how you want the AI to respond. Then start a new conversation and notice how the responses are already tailored to you without having to explain your context.

Managing Your AI Workflow

Here is something nobody tells you when you start using AI tools: if you do not develop good habits early, you will drown. I have thousands of conversations across Claude, ChatGPT, and other tools. Without a system, finding that brilliant prompt you wrote three months ago, or the document Claude produced for a specific project, becomes a needle-in-a-haystack problem. Good admin in this space saves an enormous amount of time.

Save your outputs. This is the most important habit to develop. Documents, reports, code, and other outputs you create in AI conversations do not persist forever. Conversations can be deleted, platforms change, and finding something buried in a six-month-old chat thread is painful. When an AI tool produces something you want to keep, save it immediately: download the file, copy the text to a document, or export it. Do not assume you can find it later.

Build a prompt library. When you write a prompt that works well, save it. Over time, you will develop prompts for recurring tasks: a specific way you ask for email rewrites, a template for competitive analysis, a format for meeting summaries, a prompt that gets the AI to review your writing in a particular way. Store these somewhere accessible.

NotebookLM is excellent for this. Create a notebook called "My AI Prompts" and add your best prompts as sources, organised by category. You can then ask NotebookLM to help you find and refine prompts, or generate variations for new use cases. Alternatively, a simple Google Doc, Notion page, or even a text file works. The tool matters less than the habit.

Name your conversations. Most AI tools let you rename conversations. Instead of accepting the auto-generated title (which is usually vague), rename important conversations with something descriptive: "Q1 Budget Analysis - March 2026" or "Website Copy - Assure Advantage" or "Cover Letter - DXC Role." This takes two seconds and saves ten minutes of searching later.

Use Projects and folders. Claude's Projects feature lets you group related conversations with shared files and instructions. ChatGPT has a similar Projects feature. Use them. A project for each client, each major piece of work, or each ongoing task area means your conversations are pre-organised rather than dumped into a single chronological stream.

Search works, but only if you remember keywords. Both Claude and ChatGPT now offer conversation search. Claude also has memory that draws on past conversations. These features help, but they work best when you can remember roughly what you were working on. Good naming and project organisation make search much more effective.

Periodic cleanup. Every few weeks, spend ten minutes archiving or deleting conversations you no longer need. This reduces clutter and makes the important stuff easier to find. Think of it like cleaning your email inbox. Nobody enjoys it, but everyone benefits from doing it.

A Simple System to Start With

Create three things today: (1) A document or notebook for your best prompts, organised by task type. (2) A folder on your computer called "AI Outputs" where you save anything worth keeping. (3) A habit of renaming every important AI conversation with a descriptive title as soon as you start it. These three habits will save you hours over the coming months.

ChatGPT Custom GPTs

ChatGPT has a feature called GPTs (sometimes called Custom GPTs) that lets you build specialised mini-apps. You give a GPT a name, a set of instructions, and optionally a knowledge base of files. It then behaves like a purpose-built tool for a specific task.

A real example: when I had a dispute with a former landlord who was being unreasonable, I built a negotiation GPT. I used Perplexity to research negotiation tactics and compiled them into a knowledge base. I then trained the GPT with instructions on how to apply those tactics to tenancy disputes under Australian law. Every time the landlord sent a message, I ran it through my GPT and got back a strategically crafted response. It worked. The landlord backed down.

You can build GPTs for anything: a writing style guide checker, a meal planner that knows your dietary restrictions, a tutor for a subject you are studying, or a customer service response drafter. GPTs are available to ChatGPT Plus subscribers and can be shared with others.

Choosing the Right Model

Both Claude and ChatGPT offer multiple AI models, and choosing the right one matters more than most people realise. The models change frequently, so treat this as a snapshot of March 2026.

Claude models (as of March 2026): Claude Sonnet 4.6 is the default and daily workhorse. It has improved so dramatically that developers now prefer it over the previous generation's top-tier model. For most tasks, Sonnet is all you need. Claude Opus 4.6 is the most powerful model, with a massive 1-million-token context window (meaning it can process an entire book or codebase in one go), deeper reasoning, and multi-agent capabilities. Opus is slower and uses more of your allowance, but the quality gap on genuinely hard problems is real. Use Sonnet for everyday tasks. Switch to Opus when you need the AI to process something very large or think very deeply.

ChatGPT models (as of March 2026): OpenAI has moved fast. GPT-4o, which was the standard model for much of 2024-2025, is being retired. The new default is GPT-5.3 Instant, with GPT-5.4 as the newest flagship. For reasoning-heavy tasks (maths, logic, coding, complex analysis), the o3 and o4-mini models think step by step before answering and produce significantly better results on hard problems. ChatGPT Plus subscribers get access to GPT-5 Thinking (3,000 messages per week), o3, and o4-mini.

Gemini models (as of March 2026): Google's latest is Gemini 3, with Gemini 3 Pro (most powerful, comparable to Claude Opus and GPT-5) and Gemini 3 Flash (fast and efficient, good for everyday tasks). A major strength is the 1-million-token context window across all models. Free tier users get Gemini Flash. Google AI Pro subscribers get access to Gemini 3 and integration with Google Workspace apps.

The practical rule: Start with the default model. If the answer feels shallow, incomplete, or wrong, switch to the more powerful model and try again. You will quickly learn when the upgrade matters and when it does not.
