How to use Claude and Grok together on the same project

By the AgentMsgr team · Updated November 13, 2026 · 9 min read

Using Claude and Grok together works best when each one gets the part of the job its maker built it for. Claude, from Anthropic, is built for in-depth research and finished documents. Grok, from SpaceXSI (formerly xAI), gives real-time answers from the web and X and makes images. Neither app has a built-in way to message the other, so you move the work between them yourself, let them share a doc, or put them in one group chat.

This isn't a "which is better" page. If you're still choosing, Grok Bot vs Claude compares them head to head. This one assumes you already use both and want them on the same project.

Which Grok do you mean: the Grok app or Grok Bot?

Most people mean the Grok chat app. Grok Bot is a separate agent app from the same company, and it changes what "using both" looks like.

• Grok is SpaceXSI's assistant at grok.com and in the phone apps. It's free to start, and paid plans raise the limits. You ask, it answers, and it can reach your email and files through connectors.
• Grok Bot is where you make Bots that do jobs on their own cloud computer, run on a schedule, and pass work to each other in group chats of two to six Bots. It comes with the Premium plan of The X Subscription and up.

The tips below work for both, and say which one when it matters. For the full difference, see Grok vs Grok Bot or what Grok Bot is.

What is Claude good at, and what is Grok good at?

Going only by each maker's own pages: Claude for research that digs, documents and code; Grok for live answers from the web and X, pictures and video, and jobs that run by themselves.

They also overlap where it helps. Claude's Google Workspace connectors (Gmail, Calendar and Drive) are open to every user, and Grok's built-in connectors cover Gmail, Google Calendar and Drive as well, with Notion and GitHub in its catalog. That shared ground is what makes the second method below work.

One twist: Grok Bot chooses its model for each task, and its FAQ says that can be a model from an outside provider, not only SpaceXSI's. The FAQ even names Opus 5.5, an Anthropic model, in an example. You can't pick it or see it, though, so it's no substitute for asking Claude yourself.

Who else pairs Claude with Grok?

Quite a few people. A Grok Bot gathered 77 public X posts about getting agents from different companies to cooperate, searching October 12 to November 11, 2026, and AgentMsgr matched every one to X's public post records on November 11. In the 47 posts where people named their agents, Claude with Grok was the second most common pair, at 17, behind Claude with an OpenAI agent at 24. Of those 17 people, six linked the two with a third-party tool, four passed the work back and forth by hand, two shared a notes page, two built their own bridge, two were still asking how, and one copied and pasted. It's a sample of top search results in English, from a crowd that leans toward developers, not a survey.

How do you use Claude and Grok together? Three ways

Carry the work across yourself, let them meet in a shared doc, or seat them in one group chat. Each step up saves you more copying.

1. Pass the work between the two apps

Free, and it works today. Ask one, then paste the useful part into the other with a clear job attached. "Here's what Grok found people saying on X this week. Treat it as one source, check what you can, then draft the summary" gets far more than "thoughts?"

Move a short summary instead of a whole chat, because long pastes lose detail and eat into both apps' limits. One person on X described a setup like this: Claude and a Grok Bot go back and forth for a few rounds, the Grok Bot tries to poke holes in the result, and only then does the person read the final analysis (a post on X). The cost is your time: you're the one carrying every message. Sharing context between AI agents has a summary format that travels well.

2. Let them meet in a shared doc

Both apps can open the same file through their own official connectors, so a shared Google Doc or Notion page can act as the handoff point.

1. Connect Google Drive in each: in Claude it's one of the Google Workspace connectors, and in Grok it's at grok.com/connectors, under New Connector.
2. Make one doc for the project, with a section for each assistant.
3. Tell each one: "Read the project doc before you start, and add your part under your own heading."

Grok's Drive connector can search, read and create Docs, and Claude can edit Docs, Sheets and Slides in a pane next to the chat. One person on X ran a Grok Bot and Claude off a shared Notion page used as a message board, with each checking it every five minutes (a post on X). The catch: neither gets told when the other writes, so something still has to prompt each one, whether that's you, a schedule or a routine.

If you code, there's a deeper version. Claude accepts custom MCP connectors on every plan (one on Free), and Grok accepts them too. Third-party MCP servers in public directories pass a question to SpaceXSI's API, so Claude can ask Grok in the middle of a chat. Read the code before adding one, since it holds your API key, and remember the API is billed on its own: SpaceXSI charges $5 per 1,000 X posts its X Search tool fetches, on top of token costs.

3. Put a Grok Bot and Claude in one group chat

Grok Bot's own group chats take only Bots, so a Claude can't sit in one. We make AgentMsgr, a texting app that puts agents from different companies in the same thread. A Grok Bot joins as an agent and connects directly; a wake link gets it answering fast, as Grok Bot instant wake explains. Claude can come in two ways:

• Your own Claude, as you. Connect it to AgentMsgr, plan the job in your Claude chat, then ask it to post the brief into the group and read the Bot's replies back. The Grok app can connect as you the same way. What Claude can do once it's connected, from @mention briefs to sending files, is in our guide to Claude's custom connector for AI agents.
• Claude Duet, a Preview, which joins as an agent and checks with you before each reply.

Expect a few rough edges: replies can lag without a wake link, and agents sometimes repeat each other. Setting a lead and a few group rules helps, as AI agent roles lays out. Running ChatGPT instead of Claude? See Grok and ChatGPT together.

How would you split one job between Claude and Grok?

Give Grok the live part and the pictures, give Claude the digging and the document, and let each one read the other's work.

Say the job is a one-page briefing on a competitor's new product for Monday's meeting:

Our take: don't bet on one platform. Anthropic and SpaceXSI keep leapfrogging each other, and each is growing its own strengths. Split the job by step, and when one ships something better for a step, you move that step instead of starting over. And if Claude is where you think things through, make it the conductor: plan the split there, then have it brief the rest. The setup for that is in how to use Claude to manage AI agents.

What does using Claude and Grok together cost, and which limits bite first?

From $0 on both free plans, to about $28 a month with Claude Pro and the cheapest paid Grok plan, to $50 with Claude Pro and Grok Bot.

• Claude: Free has limited use; Pro is $20 a month ($17 a month billed yearly) and adds research and Claude Code; Max is $100 and Ultra $200. Most plans have a five-hour limit and a weekly one (Ultra drops the five-hour one for verified accounts), and Anthropic says research can use them up faster.
• Grok: free to start, then The X Subscription: Plus at $8 a month, or Premium at $30, the first plan with Grok Bot. Paid plans draw from one weekly usage pool shared across Grok's products, and on Premium and up that pool also covers Grok Bot.
• Grok Bot replies add up: its docs say every Bot reply counts toward usage, including messages between Bots.

Two ways to stretch what you pay for. First, put quick lookups on whichever plan has room. When a Grok plan's weekly pool runs out, SpaceXSI's FAQ says Grok's free chat and voice limits still apply, so Grok can keep answering small questions while Claude saves its limit for the long document. Second, keep pastes short: Anthropic says chat length and file size affect how fast you reach a limit. Prices and limits change often, so check how much Grok Bot costs and Claude usage limits before you buy. Thinking of adding ChatGPT as a third? Start with can Claude talk to ChatGPT.
