People searching this are usually hoping for one specific thing — using Claude on a flight, in a place with no signal, or without burning mobile data. The honest answer depends on which “Claude” you mean, since the chat app and the coding tool work very differently here.
This guide breaks down exactly what works offline, what doesn’t, and the one real workaround developers are using.
Claude.ai (Web, iOS, Android): No Offline Mode
If you’re using Claude through the website, the iOS app, or the Android app, there is no offline mode. Every message you send requires an active internet connection, since your conversation is processed on Anthropic’s servers, not on your device.
This means:
- No airplane mode chatting
- No cached responses to browse without signal
- No downloading a “lite” version that works locally
This isn’t a bug or a missing setting — it’s how the underlying model works. Claude’s models are far too large to run inside a phone or browser app; the actual reasoning happens on Anthropic’s servers, which is why a connection is required every time.
Claude Desktop App (Mac/Windows): Also Requires Internet
The Claude desktop app feels more like a native tool since it opens in its own window with a keyboard shortcut, but it’s still sending your messages to the cloud the same way the browser version does. Installing the desktop app doesn’t unlock offline chatting.
The One Real Exception: Claude Code with a Local Model
Here’s where it gets more interesting for developers specifically. Claude Code, Anthropic’s coding tool, can technically be pointed at a locally running open-source model instead of Anthropic’s own servers.
Developers have set this up using Ollama, a tool that runs open-source AI models directly on your own computer. Once configured, Claude Code’s interface and workflow keep working, but the actual model answering your questions is running locally on your machine instead of in the cloud.
Important distinction: this isn’t “Claude running offline.” It’s Claude Code’s interface being used with a completely different, locally-hosted model. The responses come from that local model’s own capabilities, not from Anthropic’s Claude models, so quality and behavior will differ from the real Claude experience.
Roughly what this setup requires:
- A capable computer (Apple Silicon Macs with enough unified memory tend to handle this well)
- Around 20-40GB of free disk space for model files
- Installing Ollama and downloading a compatible model
- An initial internet connection to download everything, after which it can run without one
This is a genuine option if you’re a developer working somewhere with no connectivity, or want to avoid sending code to any cloud service — but it’s a separate technical setup, not a feature inside Claude itself.
Why There’s No Official Offline Claude
Running a large language model at Claude’s level of capability requires substantial computing power that a phone or laptop simply can’t provide on its own. This is true across the industry, not unique to Anthropic — genuinely capable AI chat assistants generally require cloud infrastructure to run.
Smaller local models (like the ones used through Ollama) can run on personal hardware, but they trade away significant capability to do so.
What You Can Actually Do to Prepare for Low-Connectivity Situations
Copy important conversations before you go offline. If you know you’ll lose signal, copy any responses you’ll need for reference into a notes app beforehand.
Use a lightweight local model as backup for coding tasks. If you’re a developer expecting extended offline periods, setting up Claude Code with a local Ollama model in advance is the closest available workaround.
Don’t rely on cached chat history working offline. Even previously loaded conversations may not fully load or let you send new messages without a connection.
Frequently Asked Questions
Is there a paid Claude plan that includes offline access?
No. Offline chatting isn’t available on any current plan, including Pro or Max — the limitation is architectural, not a paywall.
Can I download Claude’s model to run on my own computer?
Not Anthropic’s actual Claude models. What developers run locally through Ollama are separate open-source models, not Claude itself.
Does the Claude mobile app work in airplane mode at all?
No, sending or receiving messages requires an active connection, whether Wi-Fi or mobile data.
Will offline support be added in the future?
Anthropic hasn’t indicated plans for a fully offline Claude experience, given the computing requirements involved — but check Anthropic’s official announcements for the most current information.
Is the local Ollama setup free?
Yes, Ollama and most open-source models are free to download and run, though you’ll need enough disk space and a capable enough computer to run them smoothly.

Final Thoughts
If you’re hoping to chat with the real Claude without an internet connection, that isn’t currently possible on any platform. The only genuine offline-adjacent option exists for developers using Claude Code with a separate local model — everyone else will need a connection, even a weak one, to keep the conversation going.Claude AI Offline: What’s Actually Possible
