Verdicts

Atticus

Atticus runs a person's Mac by voice on their existing Claude or Devin plan, with a sandboxed safe mode and a local log of every command. It has no API, MCP server or documented command for another agent, it is five days old, and it rebuilds itself from the main branch every six hours by default.

Lindy

Lindy keeps what it remembers in files the owner can read and edit, and publishes credit prices. Its approval setting applies in shared Slack threads only, so writes asked for by direct message, text or web chat run unasked, which its pricing page does not say. It has no status page, and its changelog stops in October 2025.

Before you call either

Atticus

  1. Don't plan to call Atticus from another agent. It takes requests only from its own shortcut and typing box
  2. If a user runs Atticus beside you, expect it to move windows and type into apps on the same Mac
  3. Point a user who wants pinned versions to Settings > About & Updates to turn off self-update

Lindy

  1. Treat a request sent by direct message, text or web chat as unguarded. Approval prompts appear in shared Slack threads only.
  2. Run a routine as a dry run before turning it on. A dry run reads real data and sends, posts and writes nothing.
  3. Turn off unused tools after adding an MCP server. Every supported tool arrives switched on, and a large server adds more than a hundred.
  4. Expect a billed seat for anyone who mentions Lindy in Slack. A teammate who joins that way has seven free days first.
  5. Connect only hosted MCP servers on public HTTPS with streamable HTTP, the one kind the docs describe.
