Limits
Every number that bounds what June does for you, in one place: files, projects, organizations, sharing, memory, schedules, the sandbox, voice and more.
Every limit June sets, grouped by where you meet it; each row links to the page that explains it. Your ChatGPT or Claude plan's own usage windows show in the composer's meter; see Use your own plan.
