Connect Slack, Stripe, and Gmail. Marrow runs your playbooks on your data, learns how you work, and delivers briefings you can act on. Install packs from others — or publish your own when a routine is worth sharing.
You repeat the same checks every day — Slack, metrics, email — but every morning starts from scratch. ChatGPT gives advice; it doesn't run your routine on your stack.
Marrow is an operating system for how you think and work: playbooks that execute on your accounts, a brain that remembers your judgment, and a gallery where you can install — or sell — executable packs when you need them.
Two layers
What you know. What you run.
Remember
Your knowledge & voice
Ingest sources, train your brain, build skills — frameworks that compound over time. Optional on day one; deepens every week.
-> "This is how I think about pricing."
Execute
Playbooks on your stack
Multi-step routines on your connected accounts: check Slack, pull Stripe, summarize GitHub — structured output and run history every time.
-> "Here's what happened and what to do."
How it works
Connect, describe, run.
01
Connect your tools
Link Slack, Stripe, Gmail, and more via secure OAuth. Your credentials, your data.
02
Describe your routine
Tell Marrow what you check — or start from a recommendation. We build a playbook you can edit.
03
Run on demand or schedule
Get a structured briefing every run. Schedule weekday mornings so it's waiting when you wake up.
04
Install or publish packs
Add someone else's playbook and judgment to your stack — or package what you run and sell it in the gallery.
See it in action
Not a chatbot answer. A run on your stack.
Your morning playbook hits Slack, Stripe, and Gmail in order — then delivers a structured briefing you can act on.
