X caps at 280 characters, Telegram allows 4,000. Posting the short version verbatim wastes the room Telegram gives you to actually explain the thing.
X: 1-2 hashtags, zero is fine. Telegram: not needed. Carrying the tag block across is the single most obvious sign of an automated cross-post.
X penalises links in the body, so posts written for it park the URL elsewhere. On Telegram links in the body are fine — putting it back is free reach.
X is one hook and nothing else — opinionated, conversational, over in a breath. Telegram is direct and clear; formatting is light. Those are different jobs, so the same words cannot do both well — and every algorithm here demotes text that obviously was not written for it. The fix is not to skip cross-posting; it is to send a native version to each network.

PostWire's /api/generate writes those per-platform versions for you from a single prompt, respecting
every limit in the table above. From an AI agent it is one MCP tool call.
PostWire takes one idea and publishes a version written for each network — the right length, hashtags and format per platform. It also refuses posts that would fail, like a video network with no video, before they are queued.
Free for one brand — 30 posts a month, no card. Starter is $9/month for three brands and 300 posts. There is a REST API and an MCP server if you would rather automate it.
