Claude Cowork now works on your phone and in the browser. These 4 steps give every device the same Claude, the one that knows your business.
You set Claude up on your Mac. It knows your business, your clients, the way you write. Then you open Claude on your phone, ask it something, and it acts like you two never met. That's because your files live on one computer, and your phone can't reach them.
Two things travel with your account no matter which device you pick up: skills and connectors. That's the whole trick. Put who-you-are into skills, put your files where a connector can reach them, and every device gets the same Claude. The setup below takes one sitting.
Take the files that describe who you are, your voice profile, your about-me, your writing rules, and have Claude turn each one into a skill saved to your account.
Why it works. Files live on a computer. Skills live on your account, so they follow you to your phone, the browser, and any new computer you sign into.
Turn my [voice profile / about-me file] into a skill. Keep my words exactly as they are, format it as a skill file I can download, and give it to me so I can add it to my account under Settings and Capabilities.
Make a folder called Claude in your Dropbox or Google Drive and drag your Claude files into it. In Dropbox, right-click the folder and pick "Make available offline."
Why it works. A folder on your desktop belongs to one machine. A cloud folder is reachable from everywhere, and your computer still sees it as a normal folder.
In Claude, open Settings, then Connectors, browse for Dropbox or Google Drive, click Add, and approve the access when your browser asks.
Why it works. Connectors attach to your account, like skills. Once the connector is on, the Claude on your phone can read the same folder your computer uses.
This is the step people skip, and it's the one that makes the whole thing work on its own. Have Claude move its own pointers so every future chat looks in the new folder first.
Why it works. Claude checks its instructions before it acts. One clear line about where your files live, plus a fallback to the connector, means you never have to explain the setup again.
I moved my Claude files from [the old location] to [Dropbox/Claude]. Compare the two and flag anything missing. Find every place that still points to the old location and update it to the new one. Then update my main instructions with this rule: read my files from [Dropbox/Claude] first, and when a phone or web session can't reach them directly, read the same files through the [Dropbox] connector instead. Tell me your plan before you change anything.
From your phone, Claude reads your files and can create new ones, but it can't edit an existing file line by line through the connector. It replaces the file or makes a new one instead. For most phone work that's fine. Save the fine-tuning edits for your computer.
Open Claude on your phone and ask: "What do you know about my business?" If it answers with your real details instead of asking you to introduce yourself, you're done. Every device now starts from the same place.
This part didn't fit in the post. Cowork tasks that repeat, a weekly report, a morning briefing, can now run in the cloud, which means they keep running with your laptop shut.
When you create a scheduled task, set it to run on auto approval and point it at your files through the connector, not a local folder.
Why it works. A cloud task with no one watching can't stop and ask permission. Auto approval lets it finish the job while you're doing something else.
If an existing task won't let you move it to the cloud, it's because a local folder is selected on it. Deselect the folder, save, and the move-to-cloud option appears.
Why it works. A task tied to a folder on your computer has to run where that folder lives. Untie it, and it's free to run in the cloud through the connector instead.
If you only do one thing today, turn your about-me file into a skill. That alone makes the Claude on your phone sound like it knows you. The cloud folder and the connector can wait for a free afternoon, and the prompt in step 4 does the heavy lifting when you get there.
