01 · Features

What Arvlin does, exactly

Everything runs on your Mac. Nothing you scan, clean or write is uploaded.

Library

Reuse what already works

  • Search titles, tags and content; filter by favorites and recent use.
  • Import SKILL.md packages and Markdown from folders you choose; they refresh on their own.
  • Copy, or drag as text or a .md file straight into your chat.
  • Save working sets with the README and AGENTS.md of a project.

Services

Which project owns this port?

  • Local listeners with project, port, process, CPU and memory.
  • Copy the URL or port, or open it in your browser.
  • Stop a recognized dev service you own, after you confirm.

Maintenance

Review first, then decide

  • Cleans caches and old logs only when the app that owns them is not running.
  • Move to Trash and undo, or delete permanently after a confirmation.
  • Uninstall apps together with their own leftover folders.
  • Analyze a folder, your home or the whole disk; run 14 System check tasks without admin rights.

AI usage

Keep AI usage in view

  • Tokens, sessions and projects from Claude Code and Codex logs you select.
  • API-equivalent cost estimates for Claude models; an estimate, not a bill.
  • Known secret patterns are masked before anything is shown.

System

What is your Mac doing?

  • CPU, memory pressure, disk, network, battery and thermal state.
  • Top processes by CPU and memory.
  • Keep your Mac awake for 15 to 120 minutes.

Companion

One shortcut away

  • Open the mini panel from the menu bar, ⌥⌘Space or the desktop companion.
  • Library, Services, AI, System, or a Cockpit that combines them.
  • Seven languages that switch instantly.
