Claude vs ChatGPT vs Grok
Claude, ChatGPT and Grok side by side: plans, prices, usage limits, coding agents and how each connects to your apps.
All three have a free plan and let you connect your own tools. The paid tiers differ in price, how limits reset and which coding agent comes with them.
Claude Pro and ChatGPT Plus both cost $20 a month. Grok publishes its paid plans as SuperGrok tiers that share one weekly usage pool. Prices are as of November 2026.
Good for
- People picking one AI subscription
- Developers who want a coding agent included in the plan
- Teams that need the assistant to reach Gmail, Drive or Slack
- Anyone moving from one of the three to another
Side by side
Pick the plan whose coding agent, connectors and limit style match how you work, since the $20 price is the same for Claude and ChatGPT. The Grok docs pages we checked list no SuperGrok prices, so check grok.com before you compare cost.

Which to pick
Our advice: pick Claude for Claude Code and Opus models in one plan. Pick ChatGPT for Codex included on every plan and a cheaper $8 tier. Pick Grok for one weekly usage pool across chat, images, video and voice.
The limit on each side: Claude Code needs a paid plan, ChatGPT shows Codex limits as 5-hour estimates per model, and Grok paid plans share one weekly pool. The Grok docs pages we checked list no SuperGrok prices.
Best for
- Claude: people who want Claude Code with a Pro plan at $20 a month
- ChatGPT: people who want a coding agent on every plan, including Free and Go
- ChatGPT: buyers who want a cheaper $8 Go step before Plus
- Grok: people who generate images and video and want one shared usage pool
- Any of the three: teams that already run their own MCP servers
Skip it if
- Claude: you need a coding agent on a free plan, since Claude Code starts at Pro
- ChatGPT: you want one limit window, since Codex lists 5-hour estimates and says weekly limits may also apply
- Grok: you want separate limits per product, since paid plans share one weekly pool
Questions
Which is better, Claude, ChatGPT or Grok?
None wins outright. The vendors publish no head-to-head test, and the right one depends on your work and budget. Both Claude and ChatGPT start paid use at $20 a month (as of November 2026), so try the same task in each free plan first.
How much do Claude, ChatGPT and Grok cost?
Claude Pro is $20 a month, or $17 a month billed yearly, Max is $100 and Ultra is $200. ChatGPT is $8 for Go, $20 for Plus and $100, $200 or $500 for Pro. Grok's docs name SuperGrok plans but list no prices, so check grok.com. All as of November 2026.
Do all three have a free plan?
Yes. Claude Free covers chat, web search, files and connectors with limited usage. ChatGPT Free includes a limited Codex in the desktop app. Grok says it is free to start, with paid SuperGrok plans for higher limits.
Which one has a coding agent?
All three do. Claude Code comes with Claude Pro and up. Codex is included in every ChatGPT plan, with the full set from Plus. Grok Build is described in xAI's docs as a coding agent that runs in a terminal UI, headlessly or through ACP, and it draws from the same weekly pool. For the first two head to head, see Claude Code vs Codex.
Can I connect my own tools to each one?
Yes. Claude takes custom remote MCP servers on every plan, though Free is limited to one. ChatGPT on the web uses remote MCP tools through plugins. Grok accepts a custom MCP server by URL under Connectors. New to the term? Read what MCP is.
How do usage limits differ?
Claude uses a 5-hour window plus weekly limits, and Ultra has no 5-hour limit for verified accounts. OpenAI publishes Codex estimates per 5 hours for Plus and says weekly limits may also apply. Grok uses one weekly pool you spend across its products, and you can buy extra credits.
Does Grok connect to Gmail and Google Drive?
Yes. Grok has built-in connectors for Gmail and Google Calendar, Google Drive, OneDrive, Outlook, Teams, SharePoint and Salesforce. Each signs you in with OAuth, and you add them at grok.com/connectors.
What about Gemini?
Gemini is not in this table. Google lists its plans on the Gemini subscriptions page, so compare it there.
Can I use more than one?
Yes. Each is a separate subscription. All three accept custom MCP servers, so a server you built can be connected to each of them.
