OpenAI

As of October 2026, I’d think of “best AI tools” less as one winner and more as a stack. Real usage data shows people increasingly use multiple assistants: Menlo Ventures’ 2026 consumer AI report says the average AI user now uses 3.0 general AI assistants, with ChatGPT at 60%, Gemini at 58%, and Claude at 20% among AI users; Pew’s 2026 U.S. survey similarly found ChatGPT is the most-used chatbot among Americans, followed by Gemini, Copilot, Meta AI, Grok, and Claude.

My top recommendations

If you only want 3 tools

For most people, I’d start with:

1. ChatGPT — default all-purpose assistant.
2. Gemini or Claude — Gemini if you use Google heavily; Claude if you write, analyze, or code a lot.
3. Perplexity or Copilot — Perplexity for research; Copilot if you live in Microsoft 365.

My practical “best stack” by person

• Student: ChatGPT + Gemini + NotebookLM + Perplexity
• Office worker: Microsoft Copilot + ChatGPT/Claude + Grammarly + Notion AI
• Developer: GitHub Copilot + Cursor + Claude + ChatGPT/Codex
• Creator/marketer: Canva + ChatGPT + CapCut + Midjourney/Ideogram + Suno/ElevenLabs
• Small business owner: ChatGPT + Canva + Perplexity + Grammarly + Copilot or Gemini, depending on whether you use Microsoft or Google

Bottom line: If you want the most battle-tested choice, use ChatGPT. If you’re in Google, use Gemini. If you want premium writing/reasoning/coding help, add Claude. Then add specialists like Perplexity, Canva, GitHub Copilot, Cursor, Notion, Grammarly, CapCut, Suno, and ElevenLabs based on your actual workflow.

5. Video, Audio, & Music Creation

Generative media has reached a point where high-end video and audio can be produced entirely from text prompts.

• ElevenLabs
  • What it’s best for: Ultra-realistic text-to-speech, voice cloning, and sound effects.

  • What it’s best for: Workspace organization and note-taking.
  • Why people use it: If you already use Notion for organizing your life or business, its built-in AI can instantly summarize pages, draft emails, rewrite notes, and find information hidden deep within your workspace.

Summary: How to choose?

Instead of subscribing to everything (which gets expensive fast), most power-users build a personal "stack":

1. Select one general assistant (like ChatGPT Plus or Claude Pro).
2. Use Perplexity for daily searching and research.
3. Add 1 or 2 niche tools based on your job (e.g., Cursor for coding, Midjourney for design, or Fireflies for corporate meetings).

The best AI tools for most people are usually ChatGPT, Claude, Gemini, Perplexity, and Microsoft Copilot, because they’re the most broadly useful and widely recommended across general chat, writing, search, and office work.

If you want the top brands/products people actually use, here’s the practical shortlist:

A few important takeaways from the rankings:
