Every week there’s a new “game-changing” AI tool, and most of them are the same six categories wearing different logos. Once you know the categories, picking tools stops being overwhelming. Here’s the map.
Chat assistants — thinking and writing
Claude, ChatGPT, Gemini. This is where you draft, summarize, brainstorm, translate, and ask questions. If your job is words or decisions, you live here. Pick one, learn it deeply — switching between three chat tools makes you worse at all of them. Differences at the top end are smaller than the hype suggests.
Coding agents — building things
Claude Code, Codex, Cursor. These don’t just suggest code, they write files, run programs, and fix their own errors on your machine. This category is why non-programmers can now build real tools. If you’ve only used a chat window for code, a coding agent is a different sport.
Image generators — visuals
Google’s image models, OpenAI’s, Midjourney. Thumbnails, illustrations, product mockups, video stills. The skill that transfers between all of them is prompt-writing, so it matters more than the tool choice.
Video generators — moving pictures
Veo, Sora, Kling. Short clips from a text description or a still image. Impressive and still expensive per second — best used for a few hero shots, not whole videos. Most “AI videos” you see are actually AI images animated with simple zooms, which costs almost nothing.
Voice — narration and speech
Text-to-speech from Google, ElevenLabs, OpenAI. Turn scripts into narration. Good enough now that the limiting factor is your script, not the voice.
Glue — automation between tools
n8n, Zapier, Make. Not AI themselves, but the plumbing that connects everything: when this happens, do that, then ask the AI, then send the result somewhere. This is the category businesses underuse most.
How to actually pick
Start from the job, never the tool. Write down the sentence “I want to ___ without ___” (“publish a weekly video without editing for six hours”). The blank tells you the category; the category has two or three serious options; pick the one with a free tier that doesn’t demand a credit card, and only upgrade when you hit a real wall. Tool-hopping feels productive and ships nothing.
