TL;DR
- On October 21 Anthropic opened the waitlist for Claude Duet: an app where Claude sends you a brief each morning, watches your connected apps and moves tasks along. US only, for Pro and Max subscribers.
- On October 22, according to press coverage, Grok Bot (an agent app) started using Calendar, Reminders, Contacts and other phone apps, each with its own allow button. It takes a paid plan; the list is below.
- Below: the click path for each, a log to copy, and one rule: one connected app per week.
- According to Anthropic, Duet checks your apps every few hours, not by the minute; we wouldn't leave anything that can't wait a few hours to it.
- What to do: pick one app, connect it, and on Friday decide whether it stays connected.
Claude Duet and Grok Bot are two assistants that don't wait for you to type: they connect to your apps, move tasks forward and tell you when they finish or when they need your sign-off. They suit people who already live in email, a calendar and a to-do list. Neither is for everyone: Duet is waitlist-only, US-only and for Pro and Max, and Grok Bot needs a paid plan.
This week two different companies gave the same step the same name: connect. It's the button most worth reading before you press, because what comes after decides what the assistant can do.
One note before we go on: we don't have access to either one, so we haven't used them. What follows is what each company published, with dates, and where each page says you click.
Claude Duet: the morning brief, and the tasks it moves along
What happened. On October 21, Anthropic launched Claude Duet, an app where, in the company's words, Claude works as a proactive agent. Monday's roundup already covered it; here is where to click, who can use it today and what the company says it doesn't do well. Each morning it sends a brief on what matters most across your connected apps, keeps watching them during the day, and messages you only when something needs your attention. It also takes on tasks you give it, from scheduling meetings to building dashboards or forecasts. According to Anthropic, before it sends a message, makes a payment, signs a document or deletes anything, it shows you exactly what it's about to do and waits for your approval; trading securities and moving money between accounts are off-limits even with approval. You can also tell it what you want to hear about and how often. A note on the page dated October 23 says Anthropic is continuing to develop and strengthen those protections. It runs on its own virtual machine with its own browser, so your phone or laptop doesn't have to stay on. It carries over the memory, skills and connected apps from your Claude account, and you talk to it in one ongoing thread, typed or by voice.
Who has it. It's a research preview, by waitlist, US only, starting with Pro and Max subscribers. It's included in those plans and shares the usage limits of the rest of Claude. It exists as an app for iOS and Android, and on claude.ai.
Where you click. According to Anthropic's page, checked October 27:
- Go to claude.com/product/claude-duet and click Join the waitlist.
- Anthropic says it emails you when Duet is ready for you. Until then there's nothing else to do.
- When it arrives, Duet is a separate app from the main Claude app. According to the page, Duet can use the more than 6,000 connectors and plugins in the Claude Marketplace, and it brings the apps already connected to your Claude account; it names Gmail, Slack, QuickBooks, Stripe, Gusto, LinkedIn, Docusign, HubSpot, Canva and Shopify, among others.
- To take an app away, the page says you can disconnect any of the apps it has access to.
The page doesn't give the exact menu where each app is connected or disconnected. Steps 3 and 4 are what the page says, not a walkthrough we've done.
What to do with it this week. If you live in the US and pay for Pro or Max, join the waitlist today: it takes two minutes. If not, there's nothing to install; the log below works for you anyway.
Grok Bot: your phone's apps, one by one
What happened. Grok Bot is an agent app: you create Bots that sign into the apps and services you already use and do tasks in them, pausing when they need your approval. According to xAI's documentation, all the Bots on your account share the same computer. According to that same documentation, updated October 22, the phone version is for starting work, approving steps and reviewing results away from your desk, and work continues in the cloud with the app closed. On October 22, according to press coverage of the announcement, Grok Bot began rolling out use of phone apps on iOS and Android: Calendar (see your day and add events), Reminders (set and check), Contacts (find and add), Messages (read and send), Location (find places near you) and Home (control lights, locks and more). According to that coverage, each app has its own allow button and stays off until you tap it, and iMessage is not part of this update.
Who has it. According to the documentation, you need a paid individual Cursor plan, the Cursor Teams plan, an individual SuperGrok, SuperGrok Plus or SuperGrok Heavy subscription linked to your Cursor account, or a seat on a Grok Business plan. iPhone needs iOS 18 or later, and Android needs version 9 or later. According to Cursor's plans page, Grok Bot is also included on X Premium, Super and Ultra, and SuperGrok Lite can't be linked. That page lists no prices and says usage is weekly, in tiers, without giving numbers.
Where you click. According to xAI's documentation:
- Download the app (the documentation links to the App Store and Google Play).
- Tap Log In or Sign Up and finish Cursor authentication in the browser.
- If you sign in with SuperGrok, tap Link Grok Account, finish linking in the browser and tap Refresh My Status.
- On the home screen, the + control lets you choose New Bot or New Group Chat.
- Turn on notifications: that's where results, questions and approval requests arrive.
- For the phone apps, the press describes one allow button per app. xAI's documentation doesn't describe that part, so we can't tell you which screen it appears on.
We don't have xAI's original post about the phone apps: the platform that hosts it doesn't let our tools open it. The Calendar and the rest come from two outlets that covered the announcement. We haven't used Grok Bot either.
What to do with it this week. If you already pay for SuperGrok or Cursor, allow just one app, whichever helps most, and leave the rest off.
The log to copy: one app per week
It's a five-column table, one row per app. Copy it into a note or a sheet:
| App | I'm connecting it to | What I'm connecting it for | What it did this week (fill in on Friday) | Still connected? |
|---|---|---|---|---|
| [Calendar] | [Duet / Grok Bot] | [Warn me about schedule clashes and suggest openings for appointments] | ||
| [Reminders] | [Grok Bot] | [Create the reminders I dictate] |
Two rules for filling it in. You connect only one app a week. And on Friday, with the table in front of you, you decide in the last column whether that app stays connected or you disconnect it. To decide what each app can do alone, what needs your sign-off and what it never touches, use the three-column sheet in that article. This table is the next step: it tells you what you connected and what you decided to leave connected.
Four more worth a look
We read them on October 27 in OpenAI's official release notes and Google Workspace's updates blog; nobody pays us to mention them, and there are no affiliate links.
- Locked chats in ChatGPT - hides the chats you choose from history and search behind a PIN or your device login; on since October 20 for Free, Go, Plus and Pro, rolling out gradually, per OpenAI.
- Gemini Notebook inside the Gemini app - type @Gemini Notebook in a chat to create notebooks and add sources, per Google's October 23 post; off by default in the European Economic Area.
- Google Vids: speed and audio for each clip - speed from 0.25x to 2x and audio pulled out as its own clip, rolling out since October 16 and 19, per Google.
- Real-time speech translation in Google Meet - 63 languages, on web and mobile, per Google's October 23 recap.
The fine print
Duet asks for your OK before the important things. According to Anthropic, sending, paying, signing and deleting go through your approval. Anything outside that list, per the page, it can do without asking, so read what you connect before you connect it.
Allowing one app isn't allowing them all. According to the press, in Grok Bot each phone app has its own button, so you can allow Reminders without allowing Messages. According to the coverage, Messages can read and send and Home can control lights and locks: they don't weigh the same as Reminders, which is why it pays to decide app by app.
Duet doesn't look by the minute. Anthropic says it checks your connected accounts every few hours, because constant checking would burn through your usage limit too fast, and that its judgment about when to message you is still being tuned. Our advice: whatever can't wait a few hours, don't leave to it.
What runs in the background counts too. According to Anthropic, background checks come out of the same plan limit, and bigger tasks, like building a financial model or a deck, take more turns of the model.
Grok Bot doesn't change its routines from the phone. According to the documentation, on the phone you can pause, resume or delete a routine, but changing its schedule or instructions, and testing it, takes the desktop app for macOS or Windows.
What they do badly
Claude Duet. Anthropic says it plainly: it's an early version, and it may misread a thread of emails or miscalibrate what's urgent. Personal errands, like booking tickets, come out weaker, because it was built around work. It can't yet show you its browser, and it lives in its own app, separate from Claude's.
Grok Bot. According to iPhone in Canada, early reports are mixed, and one tester called it "flaky." iMessage isn't in. xAI's documentation says some advanced desktop controls don't exist on the phone. Also, per Cursor's plans page, Grok Bot usage has a weekly cap that rises with the plan, with no numbers published.
Who should skip it
If you live outside the US, Claude Duet isn't for you yet: Anthropic limits this preview to that country. If you're not on one of the plans listed above, Grok Bot isn't for you yet, and these two launches alone don't justify changing plans. And if you don't use any assistant on your email or calendar today, there's no need to start this week: the table above is there for when you do.
Where this fits in your business
These two assistants move among four things a service business touches every day: the calendar with appointments, reminders, the contact list and email. An owner with appointments on a calendar can start by asking it to warn about schedule clashes, and not add another app until a week has gone by.
Our reading: reminders, the calendar and contacts are what a business can undo most cheaply. Email is different: a message that goes out can't be brought back, which is why Duet, according to Anthropic, asks for approval before sending one. And if you want to sort out which channel the customers who ask an assistant use to find you, the SEO, GEO and AEO map explains it.
The one thing to do today
It takes 25 minutes, with your phone nearby.
- Copy the log above and write one row for each app an assistant could touch today: calendar, reminders, contacts, email.
- Pick just one, the one that hurts least if it gets it wrong, and fill in the third column: what you're connecting it for.
- Connect it if you have access. If not, join Duet's waitlist (US only) and put Friday on your calendar to fill in the fourth column with what happened.
Frequently asked questions
What is Claude Duet, and how do I sign up? It's an Anthropic app where Claude sends you a daily brief from your connected apps, watches them and moves tasks along. According to Anthropic, you sign up at claude.com/product/claude-duet with the Join the waitlist button, and the company emails you when it's ready for you.
Can I use Claude Duet outside the US? Not for now. According to Anthropic, it's a research preview in the US only, starting with Pro and Max subscribers.
Which plan do I need for Grok Bot? According to xAI's documentation, a paid individual Cursor plan, Cursor Teams, an individual SuperGrok, SuperGrok Plus or SuperGrok Heavy subscription linked to your Cursor account, or a seat on Grok Business. According to Cursor's plans page, it's also included on X Premium, Super and Ultra; that page lists no prices.
Which phone apps does Grok Bot use? According to coverage of the October 22 announcement, Calendar, Reminders, Contacts, Messages, Location and Home on iOS and Android. iMessage isn't part of that update.
Can I give it my calendar but not my messages? According to that same coverage, yes: each app has its own allow button and is off until you tap it.
Does Claude Duet see my passwords? According to Anthropic, not directly: it says it handles credentials with the same design as Claude Managed Agents, so it never directly sees your passwords or sign-in tokens.
To close
Connecting an app is one click. Choosing which one goes first takes a little longer, and it's worth the minutes.
