is team chat that stays organized.

Three things to know:

  • PostHog flags returning false — Rahul is on it.
  • Gabriel filed PRJ-128 for the AST filter.
  • Julia needs the embargo time confirmed.

Calmer than chat apps. Wired into everything.

FAQ

Questions, answered

How is Macro different from Slack?

Channels in Macro are quieter and more organized. The first few replies show inline, so you don’t open a thread every time someone responds — a busy channel reads more like a forum than a firehose. Channels also share one inbox with your email (split into Signal vs. Noise), and everything you @mention is shared with the channel automatically.

What is channel-based sharing?

@mention a doc or task in a channel and every member gets access automatically. Add someone to the channel and they gain access to everything shared in it; remove them and they lose it. It fixes the Slack-plus-Notion footgun where people constantly have to ask “can you share ___ with me?”

Can I keep using Slack?

Yes. Connect Slack under Settings → Connectors as an MCP connector so agents in Macro can still search it — useful for archives or Slack Connect with customers. Many teams run Macro for internal communication and keep Slack only for external channels during the transition.

What can I @mention in a channel?

Users, documents, tasks, files, emails, other channels, dates (@tomorrow), and groups (@here). Each mention creates a bidirectional link you can trace back later, and messages use the same rich editor — formatting, attachments, and markdown — as everywhere else in Macro.

Can agents work inside channels?

Yes — @mention @Macro to call an agent into the channel. It can summarize previous discussions, answer questions about your workspace, draft replies, and more, with the full context of your docs, tasks, and email.

Do channel members need a Macro account?

No. Anyone can be added to a channel by email, even if they’re not on your team. People without a Macro account receive an email telling them about their channel notifications.

Is Macro open source?

Yes — fully open source under the AGPLv3 (as of May 31 2026), not “open core.” To build on Macro under a different license, contact licensing@macro.com.

Bring your team together.

It takes 30 seconds to connect your account and bring channels, email, tasks, docs, and agents into one shared memory.
