The current AI tools (2026)

There are many AI tools, but a handful of assistants are what most people actually use. Here's the current landscape — with the honest caveat that this space changes fast, so treat specifics as a snapshot.

The big general assistants:

• ChatGPT (from OpenAI) — the household name; a strong all-rounder that writes, answers, makes images, and more. Free tier plus paid plans (commonly ~$20/month for the main personal tier).
• Claude (from Anthropic) — known for writing, analysis, working with long documents, and a strong safety focus. Free tier plus paid plans.
• Gemini (from Google) — deeply integrated with Google Search, Gmail, and Docs, and built into Android. Free tier plus paid.
• Microsoft Copilot — matters because it lives inside Windows and Microsoft Office (Word, Excel, Outlook, Teams), where lots of people already work.

Useful specialists:

• Perplexity — an AI "answer engine": every answer comes with clickable source citations, so it's built for research you can verify.
• Meta AI — built into WhatsApp, Instagram, and Messenger, so it reaches you inside apps you already use.
• DeepSeek — a low-cost/free challenger, notable for capable models at very low prices.

What you actually need to know:

• The "big three" people usually mean are ChatGPT, Claude, and Gemini — any one of them is a great starting point, and they're more similar than different for everyday use.
• Free tiers are genuinely useful for casual use (with daily limits and slightly less powerful models); the common paid personal tier is around $20/month and mainly buys more usage and access to the best models.
• Don't memorize model version names. You'll hear things like "GPT-5," "Claude Opus," "Gemini 3" — these change every few months. What matters is picking one assistant and getting comfortable with it.

Where to start: pick one general assistant (ChatGPT, Claude, or Gemini), use its free tier, and get comfortable. You can always add a specialist later (Perplexity for cited research, Copilot if you live in Microsoft Office). Most of this course applies to whichever you choose — the skills transfer. Don't agonize over the "best" tool; they're all capable, and fluency with one beats dabbling in five.
