Free document tools that run in your browser

Write in a free document editor, turn Word files into PDF, Markdown or text, merge them, count words and compare drafts. No account, and your files stay on your device.

Should you replace your virtual assistant with an AI worker?

Not the person, some of the tasks. What an AI worker can take off a VA’s list today, what stays with a human, and a three-question handover test.

ChatGPT Plus price in 2026: did it go up?

No, it’s still US$20 a month. What changed around it in 2026, dated and sourced, and how to decide whether to stay, downgrade or switch.

AI for teachers: planning, resources and marking across a term.

The unit plan, the worksheet at three levels, the revision deck and the marking scaffolds, in the order a term runs, and what stays with the teacher.

An AI PDF editor that changes the file.

Fill, sign, redact, OCR, merge, compress and convert a PDF next to the AI, and how to check a redaction actually worked.

AI Gantt chart maker: a schedule that moves when a task slips.

A drawn Gantt chart stops being true the first week. How to get a linked schedule from one prompt, what to check in the AI’s first draft, and how to hand it off as .xlsx or MS Project XML.

Custom AI software: the questions to ask before you sign.

Eleven questions that decide whether a build ships - what breaks if you do nothing, who owns the code and the data, what it costs to run, and what happens when the AI part is wrong.

When the estimating spreadsheet stops scaling.

It fails on history, concurrency and revision control - not volume. What a real estimating and tender system has to do, where AI helps, and why the rates stay yours.

Stop ransomware before it runs.

Antivirus asks whether a file is known bad. Application control asks whether it is known good. Why that reversal is in the Essential Eight, and what it really costs to run.

AI that runs on the computer you already own.

Why we’re working towards models aimed at ordinary CPUs instead of datacentre GPUs, what makes it genuinely hard, and why we intend to publish the work openly.

Can you run an LLM on a normal PC?

The arithmetic that decides whether a model fits your machine, why memory bandwidth sets the speed, and how to test it without trusting anybody’s benchmark - including ours.

Stop emailing the spreadsheet. Send a tool.

The workbook the team keeps breaking can be a small interactive tool nobody can break. A quote calculator, a capacity planner and a checker - one prompt each - plus the edge tests before you hand it out.

Build a company out of AI agents: hire a team, run it from a group chat.

Five agents with names, roles and goals, hired in waves, built a shoe store in an afternoon - brief, brand, model, storefront, calendar, deck, and a Monday routine. Plus the honest list of what was still missing.

How an AI agent knows it’s finished.

Acceptance checks written before the work, every attempt graded against the real file, a ledger so retries are actually different, and a handover that says what’s missing.

An AI agent is a loop. A graph is a loop with a map.

Four lines of control flow under every agent, a diagram on top, and the six things around the loop that decide whether it is safe to run while you’re in a meeting.

Improve your SEO with AI without getting penalised.

Google has said in writing what gets a site penalised, and it isn’t using AI. The seven jobs AI does well on the right side of that line - and the process this blog actually runs.

Publish your app to the web: from preview to a URL someone else can open.

Static or server, domain, HTTPS, secrets kept out of the browser, the five things that break on launch day, and the checklist to run before you share the link.

Publish an iOS and Android app: what the stores actually require.

The fees, the accounts, Google Play’s 12-tester closed-test gate, what review really checks, and the honest timeline - written after shipping both this year.

Which AI course should you do first? A path for every job.

Learn by job, not by tool. A five-minute start for everyone, then a first course for founders, marketing, sales, operations, product and education - free, timed, ending in a real file.

AI inside Word, Excel and PowerPoint: what you actually do from the task pane.

You’re staying in Office and the file is open. The five jobs a task pane is genuinely for - selection-grounded edits, range checks, real slides, the redirect, the review - and the twenty-minute install.

An AI side panel on any page - and what it should be allowed to read.

Side panel on any page, a selection with one shortcut, and a permission model you can verify in thirty seconds. The check applies to every extension you’ve ever installed.

Notion AI vs ChatGPT vs an all-in-one workspace.

Three categories, not three competitors: a wiki page, a chat thread, or a file in an editor. All three ship agents now - what separates them is what the agent hands you when it stops.

AI for tradies: one job, start to finish.

The quote, the variation, the payment claim and the schedule - followed through a single job, including the Security of Payment clock. And the parts you keep doing yourself.

AI for accountants and bookkeepers: the month-end, not the magic.

The messy client file, the working paper you can show, the report pack - and the review trail that makes it defensible. Plus the work that must stay yours.

The portal is writing the listing. Here’s what’s left.

The major portal now ships its own listing AI. The three lanes it doesn’t run - the appraisal pack, the off-portal campaign, the vendor reporting - are where agents still win.

An AI video generator that lets you direct the cut.

One prompt plans the scenes; a multi-scene timeline with captions and voice-over shapes the cut. What it does well, where dedicated generators still win, and what export looks like today.

An AI image generator with a real editor attached.

Create images with AI, then edit them in the same window - layers, masks, filters, generative fill - and drop the result into a slide, doc or video timeline.

A Microsoft Office alternative with AI built in.

Real .docx, .xlsx and .pptx files, ~397 sheet functions and a full PDF editor - or keep Office and add the same AI as a task pane in Word, Excel and PowerPoint.

Claude, Gemini or Grok? The chat window is table stakes.

All three are excellent chat windows. What a workspace adds on top: finished files in real editors, an autonomous worker, Office add-ins - compared by the job, not the model, priced in A$.

A Canva alternative with the AI built in.

Design canvas, Brand Kits, image generation with a real editor and slides in one workspace - and an honest look at where Canva still wins.

Is your business AI-ready? Five tests to run before you implement anything.

A readiness checklist that comes before the pilot: five yes/no tests on your files, tools, brand, know-how and guardrails - and why skipping them is how pilots stall.

Learn AI for beginners: a seven-day path that costs nothing.

One small task a day on the free plan and the public Academy, with the checking habit built in from day one - no jargon, no card.

Build your own app with AI: three rungs, honestly scoped.

A custom tool from one prompt, a real code editor with live preview, or a scaffolded site with zero-setup deploy - and where engineering judgment still has to come from you.

Replace your AI subscriptions, one tool at a time.

The migration playbook: what to export first, which Oppermind editor takes over, what to test for a week, and the order to cancel in.

The AI presentation maker that hands you a real deck.

One prompt becomes a deck with themes, transitions, presenter view and .pptx export - in Oppermind, or inside PowerPoint itself through the add-in.

The busy-work audit, what AI adds over rule-based automation, the four payback areas, and the human-approval line that keeps it deployable.

How much do AI subscriptions actually cost in 2026?

Nobody pays the sticker price. The current published prices, the currency and GST nobody quotes you, and three real stacks worked out in Australian dollars.

AI agents in Australia: what an autonomous worker actually does.

Most “AI agents” are a chat window with a new badge. The three tiers, the controls that make a deployment safe, and the Privacy Act obligations that land before you switch one on.

One AI subscription replaces 8. And it comes with a worker.

The average knowledge worker pays 6+ AI companies every month. Integrations don’t fix this - you still pay them all. Here’s the math, plus the feature no mainstream AI ships.

Why “built in” beats “integrated” - and always will.

Every AI integration you stack adds a subscription, a login, and another silo of your work. Native wins: on price, on speed, on where your data lives.

Nothing matches that. Try a different word, or clear the filter.
