Overview

Postmill AI combines social media content creation, scheduling, publishing, replies, and reporting in a web platform, with API and self-hosted options. The maker lists 45 channels across social, chat, blog, and email. A composer can adapt one draft by channel with previews, format overrides, brand-voice rewrites, and preflight checks. Its design studio includes a canvas, layers, brand kits, a five-track video timeline, and 36 generation studios. Scheduling tools include a visual calendar, timezone-aware recurring slots, auto-post queues, CSV bulk import, and automatic retries after network hiccups. Postmill says it snapshots metrics daily and brings replies from 19 channels into one inbox, with AI-drafted responses. Writing and replies use 30 model providers, and AI runs on customers’ own keys without credit packs, AI seat fees, or markup. The core is AGPL-3.0 open source; self-hosting on the customer’s hardware is free. Paid plans are billed monthly: Starter is 9.00 USD per month, Pro 29.00 USD per month, Team 99.00 USD per month, and Agency 249.00 USD per month.
