Accounts and plans

Signing in#

You can sign in three ways:

Email and password. Passwords need at least 8 characters.
Google. Choose Continue with Google. In the desktop app and the CLI, Google opens in your system browser, and the result comes back to a temporary listener on 127.0.0.1 (the desktop app uses port 53682). Nothing is sent anywhere else, and you can cancel at any time.
A token, for scripts: set the PERIDOT_TOKEN environment variable for the CLI. See Peridot CLI.

An account created with Google can only sign in with Google.

In Settings (the account menu at the bottom of the sidebar) you can change your profile, language and privacy options, delete your chats, and see your plan and usage.

Prices and the exact feature list are on the pricing section of the home page. See Models and effort for which models each plan includes.

How limits work#

Limits exist so everyone gets a fair share. Three things are limited:

Messages per day. Every request to a model counts, including every step of an agent run. Resets at midnight UTC.
Monthly allowance. Each plan has an allowance that depends on the length of what you send and receive, and on the model. Settings → Usage shows how much of it you have used. When you pass 60%, a small meter also appears above the chat. It resets at the start of each month (UTC).
Size of one request. A very long conversation or task is trimmed (old messages first) or, in the agent, stopped with a message to start a new one.

Tip

Agents use more than chat. Every model turn of an agent run is a request, and each bot in an AI team makes its own. For long jobs on a Free account, watch the meter.

When a limit is reached, Peridot tells you which one and when it resets. Paid plans raise all of them.

Usage insight#

In the desktop app and the web chat, open Settings → Usage. The CLI has /usage, which shows plan limits, a token heatmap of the last year and usage per model.
