ChatGPT

ChatGPT is OpenAI's general-purpose AI assistant, and for most people it is the first — and often only — AI tool they need. It drafts emails and essays, brainstorms ideas, explains difficult topics in plain language, analyses documents and data, and works through problems step by step in a single conversation. Because it remembers the thread of what you are working on, it suits longer projects as well as quick questions, from planning a trip to debugging a spreadsheet formula.

What makes it genuinely useful is its range: the same assistant that writes a cover letter can summarise a long report, draft code, or turn rough notes into a structured plan. Paid plans add more capable models, higher limits and deeper research tools, but the free tier already covers everyday use. The trade-off is that ChatGPT is a generalist — it can sound confident while being wrong, so anything factual still needs checking against a real source.

New: GPT-6 with Intelligent UI (Oct 2026) — see the listing above

Pros

• A single assistant that covers writing, brainstorming, explanation, coding help and analysis — no need to juggle specialist tools for everyday work.
• Strong first drafts and step-by-step reasoning: it works through a problem with you before you polish the result yourself.
• Remembers the thread of a conversation, so it handles longer, multi-step projects as well as one-off questions.

Watch out for

• Answers can sound confident while being wrong, so facts, figures and quotes always need checking.
• Output often needs editing to sound like you rather than a generic draft.
• The free tier has tight limits on uploads, images, voice and deep research, so heavy users hit caps quickly.

Best for

Best for: anyone who wants one everyday AI assistant for writing, ideas and explanations — students, writers, professionals and curious generalists. Who should skip it: anyone who needs verified specialist advice, cited sources, or a tool built for one narrow job.

Pricing

Free is $0 and covers everyday text chats, with limits on uploads, images, voice and deep research. Go is $8 a month, Plus is $20 a month with more capable models and higher limits, and Pro starts at $100 a month (tiers up to $500) for heavy, agent-style work. Business is $20 per user a month billed annually. Prices change, so confirm the current plans on the official pricing page before you pay.

Example

Paste a rough outline for a presentation into ChatGPT and ask it to turn it into a ten-slide structure with a title, three bullet points and a speaker note per slide. It returns a complete draft outline you can copy into your slide tool, then refine slide by slide in the same conversation — asking it to tighten the wording, add an example, or rewrite a slide for a different audience.

FAQs

What is ChatGPT best at? Everyday writing, brainstorming, explaining ideas and working through problems in plain language — plus drafting code, summarising documents and planning multi-step work.

Can I trust its answers without checking? No. Treat answers as a strong first draft and verify anything factual before you rely on it.

Is it a replacement for specialist tools? Not for work that needs verified sources or domain expertise. Use it to draft and explore, then confirm with a specialist source.
