Macro

Macro is the open source workspace that replaces a patchwork of productivity apps with one AI-native tool containing email, channels, docs, tasks, calls, and CRM. Each Macro Block feeds into one shared AI memory layer, so what you see is the same context Macro's agents act on and remember. The whole product is built to be keyboard-first: opening a doc, creating a channel, filing a task, or switching to search can all be done via keyboard shortcuts. With bidirectional linking, @mention anything: people, docs, tasks, channels, and calls link together automatically through any Macro Block. -Macro Docs are markdown-native documents with real-time CRDT collaboration, live agent cursors, and version history you can time-travel through. -Macro Chat is focused, Slack-like messaging, with inline replies and a real inbox instead of an endless scroll. -Macro Tasks can be created from any message in a keystroke, bidirectionally linked to GitHub so branches and PRs move status automatically. -Macro Calls are recorded, transcribed, and diarized by default, with transcripts fed straight to the agent. -Macro CRM is a self-updating, auto-enriched sales pipeline that stays current without manual data entry. Startups and the fast moving teams of today are trusting Macro to never lose context.

Mudroom

Mudroom is an AI email assistant that decides what actually needs your attention and quietly handles the rest. Most inboxes are not full of work. They are full of receipts, newsletters, order updates, social notifications, cold outreach and promotions, with a handful of real messages buried inside. Mudroom reads every incoming message, separates the routine from the real, and leaves your inbox holding only what a person needs to answer. It connects to email's in one click through sign in. There is no extension to install, no filters to write and no second app to check. Mudroom works inside the email itself. Routine mail moves to a Mudroom/Held label, so it is out of the inbox but never gone, and anything that reads as human correspondence, something you need to act on, or a message Mudroom is not certain about stays exactly where it is. When it is unsure, it shows you the message. That bias is deliberate. When you first connect, Mudroom runs a one time cleanup. Spam is cleared and old promotional and social mail is binned, so you start from a clean inbox instead of a backlog. After that it keeps working on a schedule in the background. Held mail in the categories that are safe to lose, meaning promotions, newsletters, notifications, social and bulk updates, moves to Trash after a window you choose, thirty days by default. Receipts and cold outreach are never binned. Starred and important mail is never touched. Anyone you have emailed is never filed away from you. Every decision is reversible in one click, one message at a time or all at once. Filing stays off until you switch it on, and if you disconnect, Mudroom puts your mail back before it deletes your data. Mudroom is built for founders, freelancers, agency owners, recruiters and anyone running a business out of a personal inbox that takes a few hundred messages a week. It is email management for people who want inbox zero without rules, folders, tagging systems or a weekend of setup. One product, one decision, made well: does this need you, or not. Gmail is live today. Outlook support is in progress.
