The best AI tool for every task (so you stop using ChatGPT for everything)
7 AI tools matched to 7 common tasks. Sign-up links, example prompts, free tier info, and a comparison table.
By Akhil Boddu · AfricanTechBroWhy one AI tool isn't enough
Most people use ChatGPT for everything. Writing, research, studying, brainstorming, job hunting. It's like owning one kitchen knife and using it to chop vegetables, slice bread, and carve meat. It technically works, but you're making everything harder than it needs to be.
Each AI tool was built with a different strength. ChatGPT is great at generating ideas quickly. It's not great at citing sources or following precise instructions. Claude writes better long-form content. Perplexity actually searches the web. NotebookLM works with your own documents instead of its training data.
Once you match the right tool to the right task, you'll wonder why you were doing it the hard way.
Here's the breakdown: 7 tasks, 7 tools, with setup links and example prompts for each.
1. Writing assignments, emails, and cover letters: Claude
What it's best for: Anything where you need clear, structured writing that follows specific instructions. Essays, cover letters, formal emails, reports.
Why not ChatGPT: ChatGPT tends to add filler. It drifts off-topic, repeats itself, and writes in that recognizable "AI voice" with words like "crucial" and "comprehensive." Claude stays on topic, follows constraints better, and produces writing that reads more naturally.
Get started: claude.ai -- sign up with Google or email. Free tier gives you limited messages per day on Claude 3.5 Sonnet, which is more than enough for most writing tasks.
Example prompt:
Write a cover letter for a junior data analyst position at Deloitte.
My background: BSc Computer Science from UCT, 6-month internship at
a fintech startup where I built dashboards in Power BI. Keep it under
300 words. Professional but not stiff.
Free tier: Yes. Limited daily messages on Sonnet. Pro plan is $20/month for higher limits and access to the strongest model (Opus).
Pro tip: Use Claude's "Projects" feature. Upload your CV, writing samples, and style preferences once. Then every conversation in that project already has your context, so you don't have to re-explain yourself each time.
2. Studying for exams: NotebookLM
What it's best for: Turning your own course material into study tools. Upload lecture slides, textbook chapters, and past papers. NotebookLM builds summaries, flashcards, and even a podcast-style audio breakdown from YOUR content, not from the internet.
Why not ChatGPT: ChatGPT pulls from its training data, which might not match your syllabus, your professor's framework, or the specific edition of your textbook. NotebookLM only works with what you give it, so everything it generates is directly relevant to your exam.
Get started: notebooklm.google.com -- sign in with your Google account. Create a new notebook, then upload your sources (PDFs, Google Docs, or pasted text).
Example workflow:
- Upload your 3 most important lecture slide decks
- Upload the textbook chapter PDFs that cover exam topics
- Ask: "Create a study guide covering the key concepts across all sources, organized by topic"
- Ask: "Generate 20 practice questions based on the hardest concepts"
- Hit "Generate Audio Overview" for a podcast-style summary you can listen to while commuting
Free tier: Yes, completely free. You get a generous number of notebooks and sources.
Pro tip: Upload past exam papers alongside your notes. Then ask: "Based on the past papers, which topics are most likely to appear? Create a focused study plan." NotebookLM will cross-reference your material with past exam patterns.
3. Research and fact-checking: Perplexity
What it's best for: Any question where you need accurate, sourced information from the live web. Market research, literature reviews, fact-checking claims, finding statistics.
Why not ChatGPT: ChatGPT doesn't search the web by default, and when it does (with browsing enabled), it doesn't show you exactly where each claim came from. Perplexity cites every source inline. You can click through and verify. ChatGPT guesses; Perplexity proves.
Get started: perplexity.ai -- sign up free. No account needed for basic searches, but an account saves your search history.
Example prompt:
What percentage of South African university graduates find employment
within 12 months of graduating? Include data from the last 3 years
and cite government or academic sources only.
Free tier: Yes. Unlimited basic searches. Pro searches (which use more advanced models and deeper web crawling) are limited to ~5/day on free. Pro plan is $20/month for 300+ pro searches/day.
Pro tip: Use Perplexity's "Focus" modes. Set it to "Academic" when you need peer-reviewed sources, or "Writing" when you want it to draft content from its research. The "Collections" feature lets you build a research library that persists across sessions.
4. Brainstorming ideas: ChatGPT
What it's best for: Generating volume. When you need 20 project ideas, 15 essay angles, 10 startup names, or a list of content hooks, ChatGPT is the fastest at throwing lots of options at you. Not all of them will be good. That's the point -- you filter.
Why ChatGPT wins here: It's more "creative" in the loose sense. It takes bigger swings, gives you more variety, and doesn't over-filter its suggestions. Claude tends to be more measured and precise, which is great for writing but can feel conservative when you're brainstorming.
Get started: chat.openai.com -- sign up with Google, Apple, or email. You probably already have an account.
Example prompt:
I'm a 3rd year computer science student who wants to build a portfolio
project that would impress South African tech companies. Give me 20
project ideas. Mix practical tools, data projects, and something
unexpected. For each, include: the idea in one sentence, which tech
stack, and estimated build time.
Free tier: Yes. GPT-4o access with message limits that reset every few hours. Enough for daily brainstorming sessions.
Pro tip: After ChatGPT generates ideas, paste the best 5 into Claude and ask it to evaluate which ones are most feasible given your skill level and timeline. Use ChatGPT for divergent thinking (generate), Claude for convergent thinking (evaluate).
5. Learning a new skill: Gemini
What it's best for: Getting structured learning plans that pull from Google's entire knowledge base, YouTube transcripts, and recent articles. When you want to learn Python, video editing, financial modeling, or anything else, Gemini builds a plan with real resources.
Why not ChatGPT: Gemini has deeper integration with Google's ecosystem. It can reference recent YouTube tutorials, Google Scholar papers, and current course listings. ChatGPT's training data has a cutoff and doesn't pull live educational resources the same way.
Get started: gemini.google.com -- sign in with your Google account.
Example prompt:
I want to learn data analytics well enough to get an entry-level job
in 90 days. I can study 2 hours per day. I know basic Excel.
Create a week-by-week learning plan with free resources (YouTube
tutorials, courses, practice datasets). Include what I should be
able to do at the end of each week.
Free tier: Yes. Gemini 1.5 Flash is free. Advanced plan ($20/month) gives you Gemini 1.5 Pro with longer context and better reasoning.
Pro tip: Ask Gemini to create a learning plan, then use NotebookLM to upload the resources it recommends. As you study, add your notes to NotebookLM and use it to generate practice questions. Two tools working together.
6. Competitor research and job hunting: Grok
What it's best for: Real-time intelligence from X (Twitter) and news. Finding out what people are saying about a company before your interview, tracking competitors, spotting hiring trends, and getting unfiltered opinions on products and services.
Why not ChatGPT: ChatGPT doesn't have real-time access to social media conversations. Grok pulls directly from X posts, making it the best tool for sentiment analysis, trending topics, and finding what real people think right now. Not what a marketing page says -- what actual users, employees, and industry people are posting.
Get started: grok.com -- available on web and through the X app. Free tier available.
Example prompts:
For job hunting:
What are people on X saying about working at Capitec? Focus on
engineering and tech roles. Include both positive and negative
sentiment from the last 6 months.
For competitor research:
Compare what users on X are saying about Canva vs Figma in the
last 30 days. What are the main complaints about each?
Free tier: Yes. Basic Grok access is free on X. Premium+ ($16/month) unlocks higher usage limits and deeper analysis.
Pro tip: Before any job interview, ask Grok: "What are the most common complaints from employees at [Company] on X and Glassdoor?" Then prepare answers that show you're aware of those challenges. Interviewers notice when you've done real research, not just read the About page.
7. Automating repetitive work: Manus AI
What it's best for: Multi-step tasks you'd normally do manually. Scraping data from websites, filling spreadsheets, sending batch emails, organizing files, pulling data from multiple sources into one report. Manus runs these tasks in the background while you do other things.
Why not ChatGPT: ChatGPT can tell you how to automate something. Manus actually does it. It runs tasks autonomously, interacts with websites, processes data, and delivers results. It's the difference between getting a recipe and having someone cook the meal.
Get started: manus.im -- sign up for early access. Manus is newer than the others, so availability may vary by region.
Example workflow:
- Tell Manus: "Go to LinkedIn, find 20 companies in Cape Town hiring junior developers, and put their names, job titles, and application links in a Google Sheet"
- Manus opens a browser, navigates LinkedIn, extracts the data, and populates your spreadsheet
- You review the results and start applying
Free tier: Limited free access during early access period. Pricing still being finalized.
Pro tip: Start with small, well-defined tasks. "Scrape the top 10 results from Google for [query] and summarize each page" is a good first Manus task. As you build confidence, chain tasks together: scrape, then organize, then draft emails based on the data.

How to actually switch
You don't need to learn all 7 tools today. Here's the move:
- Pick your biggest time sink. What task do you spend the most time on with ChatGPT that feels slow or frustrating? That's your first switch.
- Try the matched tool for one week. Just that one task. Keep using ChatGPT for everything else.
- Compare. After a week, you'll either feel the difference or you won't. If you do, add the next tool.
Most people end up using 3-4 of these regularly. Nobody uses all 7 every day. The goal isn't to maximize tools. It's to stop forcing one tool to do everything.
The real unlock
The students and professionals who get ahead with AI aren't the ones who use it the most. They're the ones who use the right tool for each job. That's a 10-minute decision that saves hours every week.
Start with one switch. See the difference. Then expand.
