Schedule everything

Queue posts across accounts with per-platform captions, cover frames, and a calendar that catches conflicts before they happen.

Agent-native MCP

A first-class MCP server so Claude and other agents can list accounts, compose, schedule, and check status — with real guardrails.

Know what happened

Per-target timelines, precise error codes, and one-click retries. No more guessing why a post didn’t go out.
