If you have tried to follow AI tools this year, you have probably felt lost in the names. ChatGPT, Claude, Gemini, Copilot, Cursor, Claude Code, Codex, Devin. New names appear every month, and every one of them claims to do everything.

Here is the trick that makes the whole market readable: stop comparing brands first. Compare kinds of tools first. There are really three kinds, and which kind you need matters more than which brand you pick. Once you know the kind, the brand choice gets much easier.

The chat assistants: ChatGPT, Claude, and Gemini

These are the front door to AI for most people. You open an app or a website, type or speak a request, and get an answer. They write, summarize, explain, analyze files you upload, search the web, and answer questions. All three have free plans, and the main paid plan of each costs around $20 a month. Prices and limits change often, so check the vendor's page before you pay.

ChatGPT (OpenAI) is the broadest of the three. It covers voice conversations, image generation, file analysis, web search, deep research, and custom assistants you can build for repeat tasks. If you want one app that does a bit of everything, this is the usual starting point. It also has the cheapest paid step below the main plan, an $8 tier.

Claude (Anthropic) is the favorite for writing and long documents. Its writing reads more natural than most, and it stays on track across long files: reports, contracts, research, and large sets of notes. It does not generate images. If most of your work is reading, analyzing, and writing, this is the one people tend to pick.

Gemini (Google) is the pick if you already live in Google's world. On paid plans it works inside Gmail, Docs, Sheets, and Drive, so you can summarize an email thread or draft a document without switching apps. It also has the cheapest paid entry of the three, at $4.99 a month.

Pick the one that fits where your work already lives. If you write all day, lean Claude. If you want one tool for everything, lean ChatGPT. If your work is in Gmail and Docs, lean Gemini. Many people end up using two: one for daily work and one for a second opinion.

The coding tools: Copilot, Cursor, Claude Code, and Codex

These are for people who write software, and they work differently from chat assistants. Instead of answering in a chat window, they work inside the code editor or the terminal, reading your actual codebase.

GitHub Copilot is the most common starting point and the cheapest paid entry, at $10 a month. It lives in VS Code, JetBrains, and other editors, suggests code as you type, and can now work in agent mode across files. It also has a cloud agent that can take a GitHub issue and open a pull request for it. If your team's work already lives on GitHub, Copilot is the natural fit.

Cursor is an editor built around AI from the start, based on the VS Code codebase. You still read and write code yourself, but completions, inline edits, chat, and agents sit close at hand, and it handles multi-file changes well. It is the pick for developers who want the most polished daily editing experience. Its plans changed recently, so check its pricing page before committing.

Claude Code runs mainly in the terminal. You describe a task in plain language and it reads the repository, edits multiple files, runs commands, runs tests, and iterates until the task lands. It is the pick for long, tightly connected changes across a codebase, and for developers comfortable working in a terminal. Entry is through Claude's $20 a month plan.

Codex (OpenAI) comes with ChatGPT plans rather than a standalone subscription, starting at $20 a month. It runs as an open-source terminal tool, an editor extension, and a cloud service where each task gets its own workspace and keeps going while your computer sleeps. It is a strong pick for terminal work and for tasks you want to hand off and check later.

The honest summary across all four: the tool writes the first draft of the code, and the developer reviews it, tests it, and takes responsibility for it. That review step is the job now, and it is the subject of a later article in this series.

The agents: Devin and the cloud agents

An agent is a step beyond a chatbot. A chatbot answers when you ask. An agent takes a task and works through the steps itself: reading files, running commands, checking its own work, and coming back with a finished result.

Devin (Cognition) is the best-known example. You give it a well-defined ticket and it opens a pull request. It works best on clearly scoped work, not on open-ended design problems. The cloud agents from Copilot, Cursor, and Codex work the same way: hand off a task, let it run, review the result.

Agents are powerful, and they are also where the most mistakes happen, because nobody watched the middle steps. The rule for agents is simple: the bigger the task you hand off, the more carefully you check what comes back.

How to choose in 60 seconds

If you mostly write, read, and answer questions: pick a chat assistant. Claude for writing-heavy work, ChatGPT for breadth, Gemini if you live in Google apps.
If you write code every day: pick a coding tool. Copilot for the lowest cost and GitHub teams, Cursor for the editor experience, Claude Code or Codex if you work in a terminal.
If you want to hand off whole tasks: try an agent, on small, well-defined jobs first, and review everything it produces.
If you are not sure: start free. All three chat assistants and Copilot have free tiers, and a week of real tasks will tell you more than any comparison article, including this one.

Two cautions before you spend anything

First, every one of these tools gets things wrong. They produce confident answers with wrong facts, wrong citations, and subtle bugs. Treat output as a first draft, not a finished product, and verify anything that matters: facts, numbers, quotes, and code that touches real users or real money.

Second, prices, models, and limits in this market change every few weeks. A plan that costs $10 today can be restructured next month, and a model name from this article can be replaced by the time you read it. Use this guide to understand the kinds of tools and what each one is for, and check the vendor's own pricing page before you pay for anything.

Frequently asked questions

Do I need to pay to use AI tools? No. The three chat assistants all have free plans that handle everyday writing and questions, and Copilot has a free tier for coding. Paid plans buy higher limits, stronger models, and features like agents and deeper integrations. Start free, and pay only when you keep hitting a limit that matters to you.

I am job hunting. Which tool helps most? A chat assistant, used well: drafting and tailoring applications, preparing for interviews, and understanding roles. Our guide to resumes and job search covers the application side in detail: https://connectingodds.com/blog/resumes-and-job-search-the-2026-playbook-eb21q. One warning: never let a tool invent experience for you. Recruiters check, and a hallucinated job on a resume ends a candidacy.

Do I need to learn to code to use AI tools? No. Chat assistants need no coding at all, and they are where most people should start. Coding tools are for people who already write software. A later article in this series covers what non-developers can build with AI tools, and where that stops working.

Will one tool eventually do everything? Probably not in the way people imagine. The tools are converging on features, but they still differ in where they run, what they connect to, and how they charge. The practical answer for most people is two tools: one for daily work and one for a second opinion or a different job.
