How Claudia compares
Claudia is a private AI assistant for iPhone. Bring your own AI key, with no account, no Claudia server, and nothing tracked. Here is how it sits next to the big chat apps and the privacy-first apps, and how it differs from the self-hosted agents we write about. We have tried to be fair, including where Claudia is not the right pick.

Claudia vs the big AI apps
The well-known apps are polished and have a free hosted tier you can start using in seconds. Claudia trades that for privacy and control: no account to create, nothing stored on a Claudia server, and your own AI key instead of a monthly subscription. Both approaches are valid. This is the trade.
| App | Account | Where your data goes | Price | Use your own key | Stored on device |
|---|---|---|---|---|---|
| Claudia | None | No Claudia server. Chats stay on your device. Your prompt goes to the provider you pick. | Free app, bring your own key | Yes, 7 providers | Yes |
| ChatGPT | Required | OpenAI servers. Trains on your chats by default, opt out in settings.3 | Free, Plus $20/mo9 | No | No, cloud |
| Claude | Required | Anthropic servers. Trains on consumer chats unless you opt out.6 | Free, Pro $20/mo | No | No, cloud |
| Google Gemini | Google account | Google servers. Some chats are human-reviewed unless you turn off Gemini Apps Activity.13 | Free, AI Pro $19.99/mo12 | No | No, cloud |
| Perplexity | Required | Perplexity servers. Free queries may be used to improve models, paid plans can opt out.14 | Free, Pro $20/mo14 | No | No, cloud |
| Microsoft Copilot | Optional, sign in for history and voice | Microsoft servers. Signed-in history and personalization.17 | Free, paid via Microsoft 36518 | No | No, cloud |
| Pal Chat | None | Developer collects no data. History stays on-device, your key talks to providers.19 | Free, Pal Pro $6.99/mo19 | Yes, bring your own key | Yes |
| Private LLM | None | Fully on-device. Runs offline, nothing leaves the phone.20 | One-time purchase, no subscription20 | Runs local open models, no key needed | Yes |
Claudia stores your chats on your device and runs no server of its own, but it is not fully offline. When you send a message, your prompt goes to the AI provider whose key you connected. Private LLM is the one app here that runs the model on the phone itself, with the trade-off of smaller on-device models.
Claudia vs self-hosted AI agents
These are not really Claudia's rivals. They solve a different problem. Claudia is a personal assistant that lives on your phone with no setup. The tools below are platforms you host yourself on a computer or a server, which gives you far more power and far more to maintain. Many people use both.
| Tool | What it is | Runs where | Setup effort | Privacy model | Best for |
|---|---|---|---|---|---|
| Claudia | Personal AI app for iPhone | Your iPhone, no server | Low: install and add a key | No Claudia server, chats on-device, inference to your provider | A private pocket assistant with zero infrastructure |
| OpenClaw | Self-hosted AI gateway and 24/7 agent | Your computer or a VPS | Meaningful: config files, a few hours | Self-hosted, data stays on your hardware | Always-on automation across your messaging apps |
| NemoClaw | NVIDIA security sandbox for OpenClaw, alpha | A locked-down container on a host | High and technical | Governed sandbox with strict file and network rules | Running OpenClaw under enterprise security |
| Hermes | Self-hosted personal assistant | Your VPS, in Docker, 24/7 | Moderate: about 45 minutes | Self-hosted, data and keys on your server | Scheduled jobs and memory across messaging apps |
| n8n | Open-source workflow automation | Self-host or n8n Cloud | Moderate | Self-host keeps data on your server27 | Connecting apps and AI into automated workflows |

The honest version
No app is best at everything. Here is where Claudia is the right choice, and where it is not.
Where Claudia wins
- Privacy posture. No account, no Claudia server, chats on your device, and an App Store label of Data Not Collected.
- No subscription to us. You bring a key you may already have and pay the provider directly for what you use.
- Choice. Seven providers in one calm app, so you can switch models without switching apps.
- It actually does things. Reads files, drafts messages, and handles calendar and reminders, and it asks before it changes anything.
Where Claudia is not the pick
- No free hosted tier. You need a paid API key, and you pay per use from the first message. The big apps give you a real $0 tier to start.
- Less brand and a smaller ecosystem than ChatGPT, Claude, or Gemini, with fewer plugins and integrations.
- iPhone only for now. No Android and no web app.
- Not fully local. Your prompt still goes to the provider you chose. If you want the model on the device itself, an app like Private LLM fits better.
