What Postel does

• Learns your voice. Postel reads your posts on X or a public LinkedIn profile and keeps every draft in your tone. You can also write in another style: Postel's own, a creator you follow, or one you describe.
• Writes from your material. Save links, articles, files, notes and YouTube and Instagram videos to your knowledge base. Postel drafts posts from them, so your posts carry what you know.
• Drafts with you in chat. Ask Postel for a post in plain words, talk an idea through with the microphone, or have it search the web for a recent topic. It drafts posts for LinkedIn and X, and full threads for X.
• Adapts posts between networks. Write once and each network gets its own version: a thread splits where the network threads and merges into one post on LinkedIn. Each version can be edited on its own.
• Schedules everything in one calendar. Set weekly posting slots, send each post to the next free one, and see every network side by side in month, week, day and list views.
• Finds what works in your niche. The viral posts library shows posts on your topics that reached far more people than usual, and you can write your take on any of them.
• Gives you post templates taken from viral posts. More than 30 post formats, such as a launch, a playbook or the numbers behind a result, each shown with real viral posts that follow it. Answer one question and Postel writes the format in your voice for LinkedIn and X, or use any viral post as a template.
• Writes your week for you. On Pro and up, Plan next week fills the free posting slots of the next 7, 14 or 28 days with LinkedIn and X posts, each built from your material, and puts them in For You, a review queue of drafts written for you. There you schedule, edit or skip each one. Turn on automatic scheduling and they go straight into their slots instead. For You also drafts posts from viral posts in your niche, including LinkedIn carousels in your brand style.
• Runs on your own AI key if you want. On Pro and up, connect an Anthropic, OpenAI or OpenRouter key; that usage bills to your provider and costs no Postel credits.
• Shows how posts did. Post and follower analytics for X, Bluesky and Mastodon on every plan. LinkedIn analytics are coming soon (submitted to LinkedIn).
• Works from your AI assistant. Postel is listed in Claude's connector directory, and the Postel MCP server lets Claude, ChatGPT, Cursor and other MCP clients draft, schedule and publish posts.

Who Postel is for

• Founders who sell through LinkedIn and want to post every week without spending every evening on it.
• Consultants and coaches whose posts bring in clients, and who need them to sound like them.
• Creators who already make videos or newsletters and want posts from that material.
• Small teams and agencies that write for a few people or a few dozen clients. Workspaces have seats and an optional approval step, and Agency runs many brands.

Postel on LinkedIn

Postel publishes to personal LinkedIn profiles; LinkedIn company Pages are coming soon (submitted to LinkedIn). A post can have up to 3,000 characters with up to 20 images, one MP4 video or one document (PDF, PowerPoint or Word), plus an optional first comment. Postel can also write LinkedIn carousels in your brand style. See the LinkedIn post scheduler for details.

Postel on X (Twitter)

Postel publishes single posts, threads with media on any post, and posts to X Communities. Natural Posting Times moves each post a few minutes off the exact time, and auto-plug adds a reply from your template once a post reaches the number of likes you set. See the Twitter scheduler and the tweet thread maker.

Postel on Bluesky and Mastodon

Connect Bluesky with your handle and an app password, or Mastodon on any server, then write, schedule and publish to them, threads included, from the same composer. Bluesky posts take up to 300 characters and 4 images; Mastodon uses your server's limit (500 characters by default) and takes images, a video or a GIF. See the Bluesky scheduler and cross-posting tool.

How Postel works

Step 1: Connect your accounts

Sign up and connect LinkedIn and X, and Bluesky, Mastodon, Instagram, YouTube or TikTok if you use them. Postel reads your recent posts to learn how you write.

Step 2: Add what you know

Add your website, articles, videos, files and notes to the knowledge base. Postel uses them as context when it writes.

Step 3: Draft posts

Ask Postel for a post or thread, start from a viral post or a post template, or review the drafts it wrote for your week. Edit anything in the editor.

Step 4: Schedule and publish

Send posts to your posting slots or pick a time. Postel publishes them to each network and shows everything in the calendar.
