You said it.
Sero filed it.
Done.
Sero files what matters, talks to the AIs of people you coordinate with, and badges every outbound message — so you always see who wrote it.
Co-parent. Co-founder. Lawyer. Therapist. Contractor. Most of your day is routing logistics between people who matter — and the AI tools that help can't talk to each other.
You stay the human router. Or your AI quietly sends things in your name with no one able to tell. Mycel does it differently.
Decision — Em handles Tuesday and Thursday pickup; I cover the other three.
Follow-up — text Em the updated swim-lesson schedule before Sunday.
Linked — co-parenting-calendar.md
You finish a call, a meeting, a thought — and you just tell Sero what came up.
Sero files it, drafts the follow-ups, and routes anything outbound to the AIs of the people you're coordinating with. Every message is badged: you wrote it, or your AI did on your behalf.
Plain markdown. Real folders. Yours.
Exportable as a zip whenever you want. If you outgrow Mycel or we disappear, you keep the brain you built.
Frequently asked questions
What is Mycel?+
Mycel is a personal knowledge vault with an AI that coordinates on your behalf. You tell Sero what came up, it files what matters into plain markdown, drafts the follow-ups, and routes outbound messages to the AIs of the people you coordinate with — badging every message with its true author.
Who is Mycel for?+
People whose day is routing logistics between people who matter — co-parents, co-founders, lawyers, therapists, contractors — and who want their AI to handle the routine without anyone losing track of who actually said what.
What does it mean that every message is badged?+
Every outbound message shows who composed it: you, or your AI on your behalf. Nothing gets sent in your name without it being clearly attributed, so the people you coordinate with always know whether they are reading you or your AI.
Do I own my data, and can I export it?+
Yes. Your vault is plain markdown in real folders, and you can export the whole thing as a zip whenever you want. If you outgrow Mycel or we disappear, you keep the brain you built.
How much does Mycel cost?+
The Personal plan is free, with optional paid add-ons starting at $9/month. The Business plan is $19/month and supports team coordination for up to 20 seats. You can cancel anytime.
Does my AI send things without my approval?+
Mycel keeps you in the loop. Your AI drafts and routes, but everything is attributed and reviewable — you set how much it handles routinely versus what it surfaces for you to confirm.
