How to Master AI in 90 Days: A Singapore Learning Path

By the WahLiao desk · Last verified 3 October 2026

You can go from occasional user to confident, everyday user of Super Intelligence, the kind of AI behind ChatGPT, Claude and Gemini, in about 90 days, at 20 to 30 minutes a day. That’s roughly one kopi break. The path below has three four-week levels: first build a daily habit, then run real projects with documents, voice and images, then design repeatable workflows and teach others. It costs nothing on free plans. If you’d like more structure, AI Singapore’s AI for Everyone is free, online and self-paced, polytechnic and university short courses run from about S$76 to S$327 after SkillsFuture funding, and citizens aged 18 and above who attend an eligible SkillsFuture AI course that ends on or after 16 September 2026 can claim six months of a premium tool free.

The one rule that matters most: practise on your own real work, every day, and check the result. Watching videos about Super Intelligence isn’t the same as getting better at using it. If you haven’t read our basics yet, start with Using Super Intelligence well; this page assumes you already know how to ask and how to check.

How to learn it properly

Getting good at this is a skill, not a pile of facts, so learn it the way you’d learn to drive or cook. Four habits do most of the work. Deliberate practice: each week has one specific skill to push on, not just “use it more”. Your own work: practise on the emails, reports, lesson plans or spreadsheets you actually have, with personal and confidential details taken out. Retrieval: once a week, write out your best prompts from memory before you look them up; what you can recall is what you’ll actually use. Reflection: keep a short log of what worked, what didn’t and what you checked.

Anthropic’s free AI Fluency course organises the same idea into four skills it calls the 4Ds: delegation (deciding what to hand over), description (explaining the task well), discernment (judging the output) and diligence (using it responsibly). They make a handy checklist for your weekly log.

Level 1, weeks 1 to 4: the daily habit

Pick one tool and stick with it for the month. Every day, give it one real task from this list of ten: draft an email, summarise a long document, rewrite something in a different tone, translate and back-translate, explain an unfamiliar term, plan a week or a trip, brainstorm options, turn notes into a checklist, prepare questions before a meeting or appointment, and critique your own draft. The skill you’re really building is checking: for every task, write one line in your log on what you verified and how. By week 4 you’ll start to notice which tasks it handles reliably and which it gets wrong.

Level 2, weeks 5 to 8: projects and the other tools

Now it’s time to stop starting from a blank chat. ChatGPT’s Projects, available on every plan including Free, keep related chats, files and instructions together so the model works from the same context each time; Claude and Gemini offer similar features, and Gemini calls its custom assistants Gems. Set up one project for a real, ongoing piece of work, with standing instructions such as “British English, short paragraphs, flag anything you are unsure of”. Then spend a week each on documents and spreadsheets (upload a report and question it closely; ask for a formula and test it on your own data), voice (talk through a problem on your walk to the MRT; practise a presentation), and image tools (a poster draft, a diagram, reading a photo of a sign or form). Before you upload anything, have another look at our guide to what happens to what you type.

Level 3, weeks 9 to 12: workflows, agents, teaching

The last month is all about repeatability. Pick three tasks you do every week and write each one down as a workflow: the input, the prompt, the check, the output. Try an agent-style tool, one that can browse, click and carry out steps for you, on a low-stakes errand, and watch what it does; our explainer on AI agents covers the risks. If you use spreadsheets or email rules, try one simple automation with Super Intelligence’s help. Build your personal prompt library, the ten to twenty prompts that have earned their place, and in week 11 teach one of your workflows to a colleague or family member. Explaining it out loud is the quickest way to find the gaps.

The 90-day plan, week by week

Week	Focus	By the end of the week
1	One tool, daily task	Seven logged tasks, one line each on what you checked
2	Context and follow-ups	Improved a reply three times instead of starting over
3	Summaries and translation	Caught at least one error by checking the source
4	Review	A list of what it does well and badly for you
5	Projects and standing instructions	One project set up for ongoing work
6	Documents and spreadsheets	One report analysed, one formula tested
7	Voice	One presentation or interview rehearsed aloud
8	Images	One visual made and one photo read accurately
9	Workflows	Three weekly tasks written as step-by-step workflows
10	Agents and automation	One low-stakes agent task, one simple automation
11	Teaching	Taught one workflow to someone else
12	Prompt library and review	Ten to twenty tested prompts saved; before-and-after comparison

The skills ladder

Level	What you can do	Typical point on the plan
Beginner	Ask one-off questions; accept or reject the first answer	Day 1
Capable	Give context, refine replies, check facts against sources, keep private data out	End of week 4
Fluent	Run ongoing projects with files, voice and images; know which tool suits which job	End of week 8
Expert	Design repeatable workflows, supervise agents, teach others, judge when not to use it	Week 12 and beyond

How to measure your progress

Keep three simple measures. Time saved: for your three weekly workflows, note how long each took before and after, including checking time. Error catch rate: count the mistakes you find; if you’re finding none, you’re probably not checking hard enough. Redo test: in week 12, repeat a task from week 1 and put the two results side by side. You may be pleasantly surprised. SWDA and the Singapore Institute of Technology also offer a free AI Ready quiz, about 12 questions and 15 minutes, that suggests courses based on your answers.
