Everything you publish, on one calendar. Everything you'd forget, captured.
SAGE is for solo creators running several streams at once — a newsletter here, a product there, maybe a novel on the side. It keeps the whole publishing schedule in one view, catches the stray todos and decisions before they vanish, and your AI sessions write into it directly, mid-conversation.

Your AI sessions already use it.
SAGE speaks MCP — the protocol your coding agents already talk. Mid-conversation, the session files the todo, the finding, the decision, and moves on. Weeks later, any agent can ask “what did we decide about pricing?” and get the answer back, with receipts. Ten tools out of the box: capture, recall, brief, link, the publishing calendar — the whole brain, readable and writable.
One calendar, every stream
Newsletters, product posts, even novel chapters — each stream keeps its colour on a single month. Go-lives, share reminders and meetings, plus a live ICS feed your normal calendar app subscribes to.
An inbox that catches strays
Todos, findings and decisions usually die in chat scrollback. Here your AI sessions file them mid-conversation over MCP — anything else arrives over plain HTTP. Triage each one in a tap: done, promote, archive.
Share one slice, safely
Mint a scoped link for a collaborator: one stream or one item, view-only or commenting, expiring when you say. No accounts, no dashboards to explain — they open the link and comment inline.
Stop losing the plot between streams.
Join the waitlist — you'll get a note when SAGE opens up, nothing else.
