Five tools become one team.
A scheduler, a design tool, an AI writer, an engagement inbox, and a reporting suite — Postmill is all of them, in one place.
45+ channels, one composer.
Reach your audience wherever they are — across social, chat, blog, and email. From X, Instagram, LinkedIn, TikTok, and YouTube to Discord, Telegram, Mastodon, WordPress, and your own newsletter, it's all one place.
Write once. Tailor it for every channel.
One draft becomes per-channel content — with previews, format overrides, and brand-voice rewrites, before anything is scheduled.
- Per-channel previews and format overrides — threads, polls, first comment
- Rewrite in your brand voice, on your own keys
- Drop in media straight from the library
- Preflight validation catches problems before they're scheduled
From blank canvas to finished post.
A full design studio — canvas, layers, brand kits, and a real video timeline — plus AI Designer and 38 generation studios. The whole creative stack in one tab.
- A full design canvas — text, shapes, images, layers, brand kits, exact sizing per format
- AI Designer builds and edits the canvas for you — layout, resize, rewrite, on-screen
- A 5-track video timeline, plus 38 generation studios (HeyGen, Runway, Suno, ElevenLabs, Stability)
- 6 stock browsers and a media library that stays ready to post
Schedule posts or publish on demand
Your posts are published across your selected channels at their scheduled time — automatically.
- A visual calendar — month, week, and list views; drag any post to reschedule
- Timezone-aware scheduling; recurring slots and auto-post queues keep it full
- CSV bulk import — fill a whole month in one upload
- Publishes automatically at the scheduled time; a network hiccup retries on its own
Run the whole campaign from one place.
A campaign keeps everything behind one marketing push together — posts, channels, files, brand assets, planning notes. Set the goals, watch them fill, and hand the client a live report.
- Goals with live progress — impressions, likes, clicks, tracked to 100%
- Auto-UTM on every link — clicks attributed to the campaign, no spreadsheets
- Posts, channels, files, brand assets, and planning notes in one shared place
- Client-ready reports — a live read-only link, or export to PDF / CSV
Know what worked. Never miss a reply.
Metrics snapshotted daily — real period-over-period trends, not one-off fetches. Best-time heatmaps, anomaly alerts, and a competitor watchlist. Every reply from 19 channels in one inbox, with AI-drafted responses.
The intelligence layer the $199/seat tools sell — built in.

All the best models. None of the markup.
Your AI runs on your own keys — 30 model providers for writing and replies, and 38 generation studios for image, video, voice, music, and avatars: Replicate, Runway, HeyGen, Suno, ElevenLabs, Stability, and more. While other platforms meter you through credit packs and AI seat fees, you pay provider price. Brand voice and brand memory make it write like you; the caps and guardrails are yours to set, not ours to sell back.
No credit packs. No AI seat fees. No upsells. No markup. Ever.
