Best AI Tools for Business (2026): ChatGPT, Claude, Gemini and Copilot Compared

ChatGPT Business (formerly ChatGPT Team) gives a team a shared, centrally managed ChatGPT workspace. Standard seats include custom GPTs, Projects, connected Apps, Company Knowledge, ChatGPT Agent for multi-step tasks and Deep Research for longer research reports, plus ChatGPT Work and Codex.

Which plan to pick: Standard seats for almost everyone. Premium seats cost five times as much and include five times the usage of Standard, with no 5-hour usage limit, so give them only to the one or two people who hit limits. You can mix seat types in one workspace.

Watch out for: usage limits. Seats include a baseline amount of use; beyond that, you buy workspace credits under flexible pricing. Set spend controls before you roll it out.

Claude Team is Anthropic’s plan for small and mid-sized teams. Its strength for a business is context: connectors let Claude search and read your Google Drive, Gmail, Google Calendar, Microsoft 365, Slack and GitHub without manual uploads, and enterprise search pulls answers from across those tools. Team seats also include Claude Code, Cowork, and Claude’s design, slides and document tools.

Which plan to pick: Standard seats, which include more usage than the individual Pro plan. Add Premium seats, with 5 times the usage of a Standard seat, only for heavy users. You can mix seat types.

Watch out for: limits are per person and include a weekly cap. If one person runs out, others are not affected, but that person must wait for the reset or use extra usage, which is billed at API rates.

Disclosure: this guide was drafted with help from an AI model made by Anthropic, the company behind Claude. We ranked Claude on the same published facts as the other tools.

If your business runs on Gmail, Google Workspace is the cheapest way to put AI in front of every employee, because it comes with the email, storage and meetings you are already paying for. Business Starter includes Gemini in Gmail and chat with the Gemini app. Business Standard adds Gemini in Docs, Meet and other apps, expanded access to Gemini Notebook, meeting recordings, 2 TB of pooled storage per user and eSignature.

Which plan to pick: Business Standard. It is the first plan where Gemini works across Docs and Meet as well as Gmail. Business Starter is $8.40 per user per month on Google’s Flexible Plan. Google’s pricing page showed us euros on this check, so confirm the current US price of Standard and Plus before you buy.

Watch out for: promotions. Google advertises introductory prices for new customers on the first 20 users for 12 months, after which standard pricing applies. Budget on the standard rate.

Microsoft 365 Copilot Business puts AI into the Microsoft apps many small businesses already use every day: drafting in Word and Outlook, analysis in Excel, decks in PowerPoint and meeting help in Teams. Microsoft sells it to businesses with up to 300 users that already have a qualifying Microsoft 365 Business plan.

Which plan to pick: add Copilot Business to the people who spend most of their day in Office documents and email. You do not need it for every user.

Watch out for: total cost. The $21 per user per month is on top of your Microsoft 365 Business subscription. Microsoft’s pricing page also shows a promotional $18 for the first year on annual plans bought between July 1 and December 31, 2026; after that the list price applies. Budget on $21 plus your Microsoft 365 plan.
