The 7 tools worth knowing in 2026
1. ChatGPT (by OpenAI)
Best for: general-purpose assistant, writing, brainstorming. Free tier: yes (uses GPT-5 mini). Paid: $20/month unlocks GPT-5, image generation, custom GPTs. Weakness: can be overly wordy; sometimes confidently wrong.
When to use it: your default for 80% of tasks. If you're going to learn one tool only, pick this one.
2. Claude (by Anthropic)
Best for: long documents, careful reasoning, code, thoughtful writing. Free tier: yes. Paid: $20/month. Weakness: no image generation in most tiers.
When to use it: when output quality matters more than speed — essays, reports, important emails, code review.
3. Gemini (by Google)
Best for: tasks that need current information (it integrates with Google Search), summarising YouTube videos, Google Docs/Sheets integration. Free tier: yes. Paid: bundled with Google One.
When to use it: research involving current events ("what happened in Kenya politics this week"), or anything in the Google Workspace ecosystem.
4. Perplexity
Best for: research with sources. Every answer comes with citations. Free tier: yes (limited). Paid: $20/month.
When to use it: when you need to cite something or verify claims — Perplexity links you to the actual web pages, which ChatGPT/Claude rarely do.
5. NotebookLM (by Google)
Best for: uploading a PDF/document and asking questions about it. Will never hallucinate outside the source. Free.
When to use it: studying a textbook, past exam papers, policy documents, legal contracts. Upload → ask questions → get answers grounded ONLY in that document.
6. Khanmigo (by Khan Academy)
Best for: primary/secondary homework help with Socratic-method tutoring (asks you questions back instead of giving the answer). Specifically designed for under-18 learners. Cost: $4/month via Khan Academy.
When to use it: your child's homework — safer than ChatGPT because it won't just give them the answer.
7. Photomath
Best for: maths homework. Take a photo of a maths problem — it gives you step-by-step worked solutions. Free tier: yes, with paid upgrades.
When to use it: Grade 6-12 maths. Especially good for algebra, geometry, trig.

| Child\'s homework (safer tutoring) | Khanmigo |
| Maths problem solved step-by-step | Photomath |
| Image generation (posters, social media) | ChatGPT (paid) or Gemini |
The "use two AIs" trick
Pro move: ask the same question to ChatGPT AND Claude. Compare the answers. The overlap is where both agree — probably true. The divergence is where to be suspicious. This simple "two-AI check" catches hallucination better than any single model.
What NOT to pay for
- AI-writer tools (Jasper, Copy.ai) that cost $50/month. They\'re wrappers around ChatGPT/Claude. You can get 90% of the value from the underlying models directly.
- AI resume builders. Paste your existing CV into Claude and ask "rewrite this for [job description]." Free, better.
- Obscure AI chatbots that appear in WhatsApp. Many are thin ChatGPT wrappers with data-privacy concerns. Use the real thing.
