Claude App vs. Website: Which Client Should You Use?

The Claude model you talk to is the same whether you open the desktop app, the phone app, or the browser at claude.ai. What differs between clients is how you access Claude, what features are available in each, and how well each one fits your working style. For teams or people who want project context to carry over between sessions, tools like fenbs keep the shared work record outside any one client so it is always available wherever you open Claude.

This comparison covers the three ways to use Claude — desktop app, phone app, and web browser — and explains where each one is the better fit. It also covers what to check when continuity across sessions or between colleagues matters.

At a glance: the three Claude clients

The key practical difference: MCP tool connections — which let Claude read and update outside tools such as fenbs — are available in the desktop app and developer-oriented clients like Claude Code. They are not available in the standard browser interface. If your workflow involves Claude acting on connected tools, the desktop app is the right starting point.

The desktop app: connections and keyboard access

The Claude desktop app for macOS and Windows stays accessible from the menu bar or taskbar, which means you can summon Claude with a keyboard shortcut from any other app. That is useful for quick questions while you are writing in another tool, looking something up while in a meeting, or staying in flow without switching to a browser tab.

The more significant capability is MCP support. From the desktop app, Claude can connect to tools over MCP — the standard way for an AI assistant to read and update an outside system. That includes project management tools, code editors, and shared work records like fenbs. If you want Claude to read your project context, check a task, or save progress at the end of a session, you need the desktop app or a compatible developer client.

The phone app: mobility and voice

The Claude phone app gives you the same underlying model in a format suited to mobile use. Voice input lets you ask questions without typing, which is useful while commuting, between meetings, or anywhere a keyboard is inconvenient. Project context you saved in a Claude Project is accessible in the phone app, so you can continue a conversation you started on desktop.

The phone app is well suited for quick lookup tasks, short-form drafting, and on-the-go questions. It is less suited for long writing sessions, complex multi-step analysis, or anything where working on a small screen with a virtual keyboard creates friction. Most people keep the phone app for convenience and the desktop or browser for sustained work.

The browser: universal access, no installation

The claude.ai browser interface works on any device and any operating system. There is nothing to install, and it is the fastest way to try Claude for the first time. For one-off questions, quick drafts, or situations where you are on a device that does not have the desktop app installed, the browser is the right option.

The browser interface does not support MCP tool connections in the standard Claude web chat. If you want Claude to connect to outside tools during a session, you need the desktop app or a compatible client. For straightforward text conversations that do not require outside tool access, the browser works as well as any other client.

Claude Projects: context that follows you across clients

Claude Projects let you save instructions and context that Claude reads at the start of every conversation in that project, across the desktop app, phone app, and browser. That gives you a consistent starting point without re-explaining your project each time.

Projects are personal — they are in your Claude account and are not shared with teammates unless you are on a Claude Team plan. For shared work that needs to reach colleagues using different AI tools or different accounts, an external shared record is more flexible than a single-account Claude Project.

Which client fits which situation

• For sustained writing, analysis, or coding work at a desk: the desktop app keeps Claude available alongside your other tools.
• For connecting Claude to outside tools via MCP: the desktop app is required; the browser does not support MCP connections.
• For quick questions or on-the-go use: the phone app is the right fit.
• For any device without the desktop app installed: the browser works well for text conversations.
• For shared project context that travels with you across clients and colleagues: use an external shared work record alongside any Claude client.

How to do this with fenbs

1. Create a free account and set up a project with a short goal description and the current tasks. This is the record your Claude sessions will read.
2. Install the Claude desktop app and set up the fenbs MCP connection from Integrations. Follow the integration guide to approve the connection in the desktop app.
3. Ask Claude to read the project context at the start of each desktop session. It will read Rules, Where we left off, and current tasks before it starts.
4. Save progress before you close the session. Ask Claude to update the current task status and record where the work stands. That record is available the next time you open any connected client.
5. On the phone app or browser, you can still read the fenbs project through the web interface to check what was left off, even if those clients do not connect via MCP directly.
