The Short Answer
Start with ChatGPT (chatgpt.com) or Claude (claude.ai). Both have free tiers, require nothing more than an email address to sign up, and work in any browser. Decision paralysis about which AI to pick is the #1 thing that keeps beginners stuck. Pick one today and start using it.
The Slightly Longer Answer
Here are the three tools most educators start with in 2026:
ChatGPT (OpenAI) — The most widely used AI tool on the planet. The free tier gives you access to GPT-4o, and there are more beginner tutorials available for ChatGPT than any other tool. If you get stuck, a quick search will find someone who has solved the same problem.
Claude (Anthropic) — Tends to give longer, more nuanced responses. Works especially well for educational writing, explanations, and drafting course content. Many educators find Claude’s responses feel less "robotic" than other tools. The free tier is generous.
Gemini (Google) — If you already live inside Google Workspace (Docs, Gmail, Sheets), Gemini integrates directly into those tools. Lower learning curve if Google is already your home base.
What Actually Matters More Than Which Tool You Pick
The tool matters far less than the habit of using it. An educator who uses ChatGPT free every day for 30 days will get far more value than someone who spent those 30 days researching which AI is "best."
Here is a simple rule: pick the free version of one tool and use it for at least one real task before comparing alternatives.
After two or three weeks of regular use, you will naturally have a sense of which tool fits your style. That’s when switching or comparing makes sense — not before you start.
Practical Next Step
- Go to chatgpt.com or claude.ai right now
- Sign up with your email address (takes under two minutes)
- Ask it to help you write a short description of a course you currently teach
- See what comes back
That one experiment will teach you more than any comparison article ever could.
