Get started
Quickstart
Start a private chat in your browser, with no account and nothing to install.
Open the chat app
Go to chat.thinkr.sh. You need no account, no email address, and no wallet.
Send your first message
A new chat starts in the private lane, on GPT-OSS 120B. Type a message and send it. Before the message leaves, your browser verifies the enclave's remote attestation and encrypts the message to it.
See the verification
The label "Private · Verified" shows that the verification passed on your device. The page Verify shows each of its steps, with a link to the signed release in a public transparency log. If the verification fails, the label reads "Private · Not verified", and nothing is sent.
Pick another model
Open the model picker in the message box. Each model carries the badge of its lane: "Private" for the private lane, and "No retention" for the open lane. A model that the free trial does not cover shows "With credit".
The free trial
The free trial covers three models, with 10 chats a day in each lane.
| Lane | Models | Chats a day |
|---|---|---|
| Private lane | GPT-OSS 120B | 10 |
| Open lane | Claude Haiku 5.5, GPT-6 Luna | 10 |
- The note under the message box shows how many chats you have left today.
- The counts start again at 00:00 UTC.
- On a busy day, the trial of a lane can fill up for everyone. The note then says that it opens again at 00:00 UTC.
To count your chats with no account, Thinkr's proxy computes a keyed hash of your IP address. It holds the hash and the counts in memory only, and never stores your IP address.
