Private AI chat: what is actually private in 2026
Private AI means different things: local models, no-log hosted chats, browser-only history. What each protects, what it does not, and how Unrestricted AI’s Private chat works.
Short answer
The only fully private AI is a local model (prompts never leave your machine). Hosted services can only reduce what they keep. In Unrestricted AI, Private chat keeps messages in your browser only, never in our conversation database; the model provider still processes the text, and we keep account-linked usage metadata (checked 9 Nov 2026).
Four kinds of "private"
| Kind | Example | Protects against | Does not protect against |
|---|---|---|---|
| Local model | Ollama, LM Studio | Everyone else seeing prompts | Your own device being compromised |
| Browser-only history | Unrestricted AI Private chat | Chats sitting in a company database | Provider processing; usage metadata |
| No-log hosted chat | Venice private mode, notrack.ai (their claims) | Long-term storage, if true | You cannot audit it |
| Regular chat | ChatGPT default | Nothing beyond the policy | Training and retention per policy |
How to check any private AI claim
- Read where history is stored: device, account, or both.
- Check whether the model provider (a third party) receives your text.
- Look for retention periods and training opt-outs in the privacy policy.
- Prefer claims you can verify (local, open-source clients) over promises.
FAQ
Is Unrestricted AI anonymous?
No. You need an account for the free tier, and providers process your text. Private chat keeps the conversation history in your browser only.
Can staff read my saved chats?
Saved chats are stored in our database so you can reopen them on any device; no admin interface shows them. Private chat never reaches that database. See the privacy policy.
Do I need to be 18?
Yes. Our terms require users to be at least 18.
