Anthropic Brings Claude Cowork to Web and Mobile, Extends Fable 5

Anthropic put Claude Cowork on the web and on mobile. The company said Tuesday that the agent feature is in beta outside its desktop app, with paid subscribers gaining access first on the Max plan and other paid tiers following over the coming weeks. Cowork sessions now run on Anthropic’s servers, so a task started at a desk can be checked on a phone, and scheduled jobs keep going while the laptop is closed. Anthropic used the same update to extend Claude Fable 5 access on paid plans through July 12.

The Fable 5 extension is the smaller of the two moves. Fable 5 was supposed to move to a token-based usage system on July 9; Anthropic pushed that switchover and left paying users on the current weekly terms for five more days. Cowork’s mobile rollout is the larger shift, with an access window that grows as more paid plans get added in the weeks ahead.

Cowork Leaves the Desktop Behind

Until Tuesday, Claude Cowork was a desktop-only feature. Anthropic asked users to install the Claude desktop app, give it access to local files and a browser, and let the agent run on those surfaces while a session was active. That requirement cut the addressable audience to anyone willing to install a third-party app, and on managed work devices it cut many more. Cowork on web and mobile lifts that constraint by running tasks on Anthropic’s cloud rather than on the user’s machine.

“Cowork is where you hand Claude a task, and it works across your files, calendar, email, messaging app, the web, and the other tools you connect until the job is done,” Anthropic said in announcing the change.

The beta is rolling out over the next several weeks, starting with the Max plan and expanding to other paid tiers. A task that used to require a running desktop can now be started on one device and reviewed on another. Mike Krieger, Anthropic’s chief product officer, posted that chat and Cowork have merged into a single tab on web and desktop, with one sidebar, one search, and one home for Projects and Artifacts. Sessions and files follow the user across devices. The desktop app stays the only place where Cowork can reach local files and a local browser, Anthropic said, and for anyone who could not install the desktop app, web and mobile Cowork is the missing piece.

What Cowork Now Does Across Devices

The mobile and web builds of Cowork use the same agent architecture that already runs Claude Code, with no terminal required. Users describe an outcome, and Claude handles multi-step work across connected services: email, calendars, files, messaging apps, CRMs, and web tools. Permission prompts now reach whichever device the user has open when Claude needs a decision, instead of routing them only to a desktop.

“Permission prompts reach you on whichever surface you’re using, so you can approve an action from your phone while Claude keeps working,” Anthropic’s help center says. Background work is the larger change: scheduled tasks run on Anthropic’s servers in isolated environments, so they continue even when no device is online. A weekly metrics deck can be set to run at 6 a.m., and the finished file is waiting by the time the user opens the app on a phone. Nothing ships to a final deliverable until the user signs off.

Three concrete scenarios on Anthropic’s product page show what Cowork is meant to handle:

1. Build your weekly metrics deck. Attach campaign exports and schedule a weekly task; Claude assembles a four-slide deck with recommended actions for review every Monday.
2. Walk in fully prepared. Connect CRM, call recordings, messaging, calendar, and email; Claude builds a brief for every meeting with attendees, recent threads, and what is new at their company.
3. Organize your audit. Attach a folder of policies and contracts; Claude renames every file, sorts by control area, and flags coverage gaps.

The Knowledge Work Tilt in Cowork’s Usage

Anthropic built Cowork on the Claude Code agent stack and quickly saw what users did with it. “Per Anthropic, more than 90 percent of Cowork usage has come from everyday knowledge work rather than software development,” according to a Mashable write-up of the company’s Tuesday post. Business operations and content creation together represent roughly half of all activity: reconciling quarterly spending, turning contracts into renewal trackers, and building presentations out of call transcripts. That mix is the reason Anthropic put Cowork in the same chat surface as Claude’s regular conversation tab instead of burying it behind a developer menu.

Anthropic is extending the doubled Cowork usage limits through August 5 to support that bet. The boost is framed as temporary. Cowork consumes plan capacity faster than chat, so a heavier user reaches the cap faster. Mobile and background sessions draw from the same budget as desktop ones, and a phone-managed overnight task uses the same allocation an in-desk session would.

The Five-Day Reprieve for Claude Fable 5

The Fable 5 update lives inside the same Tuesday announcement, for a different reason. Fable 5 launched on June 9 as Anthropic’s first public Mythos-class model, was suspended three days later after US export controls were applied, and was redeployed on July 1 once those controls were lifted, as covered in the export control order and what triggered it. Throughout that stretch, paying subscribers had a temporary window to use Fable 5 within their weekly limits.

That window was supposed to close on July 9, when Fable 5 access would shift to usage credits. Anthropic is extending it through July 12, per Anthropic’s June 30 Fable 5 redeployment note. “We’re extending access to Claude Fable 5 on all paid plans through July 12,” the company’s Claude account posted on Tuesday (in Anthropic’s Tuesday Fable 5 extension post). Anthropic did not give a reason. Up to 50 percent of weekly limits can still be spent on Fable 5, and users who hit that ceiling can keep working with credits or switch to another Claude model.

Plans, Limits, and the August 5 Cliff

Cowork is included on every paid Claude plan, with no separate add-on. The plan prices published on Anthropic’s product page have not changed with the mobile launch. Pro brings Cowork plus standard chat for $17 a month on the annual subscription or $20 if billed monthly.

Max ships in two sizes. Max 5x is $100 a month and is positioned for everyday longer or more complex tasks. Max 20x is $200 a month and is built for power users who hand off work throughout the day, per Anthropic. The product page notes Cowork consumes plan limits faster than chat, which is why heavier users are pushed toward Max.

Team runs $20 per seat per month and includes the Slack connector on standard and premium seats. Enterprise adds admin controls, usage analytics, an Analytics API, and OpenTelemetry observability, though Cowork activity is not yet captured in audit logs or the Compliance API. Across paid tiers, Anthropic is extending the doubled Cowork usage limits through August 5, after which the temporary boost lapses back to standard rates unless it gets renewed.

The temporary-limits framing is a tell that Anthropic is still calibrating demand. Here is how the plans and the framing stat line up right now:

• Pro: $17/month on annual subscription ($200 billed up front); $20/month on the monthly plan.
• Max 5x: $100/month.
• Max 20x: $200/month.
• Team: $20 per seat/month.
• Cowork knowledge-work share to date: more than 90 percent of usage.

The Agent Field Cowork Just Joined

Until Tuesday, Cowork’s main constraint was the desktop install. Removing that puts it in the same room as ChatGPT’s agent mode and Google’s Gemini Enterprise Agent Platform, both of which already let users hand off multi-step work across cloud tools. Cowork’s pitch on the cross-device front is that the same session can move from a desktop to an iPhone and back, with permission prompts routed to whichever device the user has open, the same trade Larry Hollar and others in the agent space have framed in how the agent bet is reshaping the AI investment frame.

Early enterprise users on Anthropic’s product page say what that looks like in practice.

In most AI chat tools, you’d query Slack, then query Databricks, then manually stitch the results together. Cowork can do all of that in a single pass. That’s a fundamentally different kind of capability.

The quote is from Larisa Cavallaro, an AI Automation Engineer, on Anthropic’s Claude Cowork product page. Other early voices on the same page frame Cowork as cutting rework rather than replacing judgment. Anthropic’s broader agent platform stays constrained by an export-control history that lifted June 30, and Fable 5 is still on a credit-meter trajectory once the July 12 extension ends. The next quarter will tell whether mobile access moves more paying users onto Max.

What Could Still Trip the Rollout

Three friction points could slow the cross-device bet. The beta is gradual, so anyone not on Max has to wait, and Anthropic has not published a calendar for when Pro, Team, or Enterprise will get web and mobile Cowork. The desktop app remains the only way to grant Claude access to local files and a local browser, and Anthropic’s announcement concedes that point. Mobile permission flows are untested at scale, and Anthropic’s help center still lists some Cowork capabilities that are not yet available on every surface.

The August 5 cliff on doubled usage limits is the closest near-term test. Anthropic is asking users to try more, run more, and keep tasks running in the background, then watching what happens when the temporary budget resets. If demand stays above the un-doubled cap, Anthropic will have its answer on whether Cowork’s main constraint right now is the desktop app or the subscription tier.

Frequently Asked Questions

When can Pro plan users use Claude Cowork on mobile?

Anthropic said the beta is rolling out over the next several weeks, starting with the Max plan first and with additional paid tiers to follow. The company has not published a calendar for when Pro, Team, or Enterprise gain web and mobile Cowork access.

Does Claude Cowork on my phone need the desktop app?

No. Cowork’s mobile and web builds run tasks on Anthropic’s servers in isolated environments, not on the user’s machine. The desktop app stays required only for tasks that need access to local files or a local browser, such as renaming a folder of contracts on the user’s drive.

What happens to Claude Fable 5 after July 12?

Paid-plan access ends on July 12, and Fable 5 moves to usage credits. Anthropic has not published a new permanent token price for Fable 5 since redeploying it on July 1, and the model’s underlying Mythos 5 sibling remains restricted to a narrower set of US organizations.

Why did Anthropic delay the Fable 5 switchover?

Anthropic has not explained the extension publicly. The Tuesday announcement keeps paying users on the current weekly terms through July 12 and shifts Fable 5 to credits-based access on the same day, which lines up with the original July 9 deadline rather than pushing that switchover out further.

Will the doubled Claude Cowork usage limits stay past August 5?

Anthropic has not said so. The temporary increase is set to lapse back to standard rates on August 5 unless the company extends it again, and the framing in Tuesday’s post described the doubled cap as a temporary boost tied to the rollout itself.
