Session

Claude Code Session is functionally a conversation to the Claude Code agent. Resuming a session is the same as resuming a previous conversation.

When you type claude you are starting a new session.
Claude Code offers two types of session: Web (remote) and Local (terminal).
A session started via Remote Control or Claude Code for Web can be continued locally via the IDE ("Past Conversations" → Local/Web tabs).

Subscription current session:

Shows how much of your plan's five-hour usage limit you've used so far, plus the amount of time remaining in that session.
All Claude plans — Free, Pro, Max, Team, and Enterprise — operate on session-based quotas that reset every five hours.
Usage within a session is determined by message length, attached file size, conversation length, and platform demand.
Claude Code has its own concept of "sessions" which you can also think of as conversations.
