ChatGPT
OpenAIより
The default general assistant. Broad enough for everyday writing and light tool use, and less predictable than Claude when a long edit has to stay careful.
- 向いている用途
- People who want one chat for drafts, summaries, and occasional multi-step tasks.
- 料金の目安
- Free tier and paid individual, team, and enterprise plans.
ChatGPT is the product most readers already have open. It is a fair first stop for writing and a capable general agent surface. It is not the tool to pick only because it is familiar when the job is code review or a citation you can audit.
合うところ
- Widest everyday surface: writing, files, and light agents in one place.
- A free tier that is enough to learn the habit.
合わないところ
- Long edits can drift.
- Plan names and limits change; read the current pricing page.

文章の他のツール
- Claude — The best default for long documents and careful agent-style work. Easier to steer than most chats, and less of a do-everything platform than ChatGPT.
- Devin Oncall — An on-call agent that starts the moment an alert fires, digs through telemetry and code, and hands you a fix as a pull request.
- Gemini — Worth opening when the work already lives in Google, or when you want image generation in the same chat. Not the first pick for code or a long edit.
- Grok Voice 3.0 — A speech-to-speech model for voice agents that tops a third-party index at the same price as its predecessor.
