The short version
| Tool | Try this | Access condition |
|---|---|---|
| ChatGPT | Ask one question or revise a short draft. | Guest access varies by country and network. Sign in to save a chat. |
| Lumo | Start a basic browser chat. | Proton offers chat before registration. Check plan details for uploads and projects. |

Choose by what you want to do
For one question, open a guest chat and check that the message box is available. To ask about a page already open in Brave, start from Leo in the browser.
Keep a copy of a result you need later. Guest access, chat history and uploads depend on the provider and the feature you use.
When you need an ongoing free plan
For regular work, check whether history, the output you need and recurring usage are available before moving your work into one tool.
A few more details
Will every feature work without an account?
Guest access covers the stated starting task. For example, OpenAI requires an account to save chats, and the available features may vary.
