The major assistants

Most people only ever try one chatbot, but they have real personalities and strengths. Here are the four worth knowing:

• ChatGPT (OpenAI) — the versatile all-rounder. Strong at general tasks, voice conversations, and image generation, with a huge ecosystem of add-ons.
• Claude (Anthropic) — excels at long documents, careful and nuanced writing, coding, and following detailed instructions. Comfortable digesting very large amounts of text at once.
• Gemini (Google) — deeply tied into Google Workspace, so it shines if you live in Gmail, Docs, and Drive, and it leans on Google's search.
• Perplexity — built for research. It answers with citations from the live web, so it's the go-to when you need sources you can click.

There are excellent others — Microsoft Copilot, Meta AI, open models you can run yourself — but mastering one or two of the above covers the vast majority of everyday needs.

How to pick

Match the tool to the job, not the brand:

• Need cited, up-to-date research? Reach for Perplexity.
• Editing a long report, or doing careful writing or coding? Claude.
• Already working inside Gmail and Google Docs? Gemini.
• Want a flexible daily driver with voice and images? ChatGPT.

Free vs. paid

Every one of these has a genuinely useful free tier — start there. The paid plans (usually around $20/month) unlock the smartest models, higher usage limits, and features like file uploads and web browsing. A good rule: use the free version until you hit its limits often enough to feel annoyed, then upgrade the one you reach for most.

You don't need every tool — you need the right one for the task, and enough familiarity to switch when the job changes.
