What changes, one by one

You have 1,700 characters you are not using

Bluesky caps at 300 characters, Discord allows 2,000. Posting the short version verbatim wastes the room Discord gives you to actually explain the thing.

The hashtag rules are not the same

Bluesky: 1-2 specific hashtags. Discord: not needed. Carrying the tag block across is the single most obvious sign of an automated cross-post.

Why copy-paste cross-posting underperforms

Bluesky is indie and anti-corporate — polished brand voice reads badly. Discord is casual and short, like talking in a channel. 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.

Publish to both in one call

curl -X POST https://postwire.io/api/post \
  -H "Authorization: Bearer $POSTWIRE_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "platforms": ["bluesky", "discord"],
    "text": "Your post",
    "per_platform": {
      "bluesky": { "text": "The Bluesky version" },
      "discord": { "text": "The Discord version" }
    }
  }'

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.

Do this without writing the post twice

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.
