One post in. A publishing plan for every platform out.

Each version gets its own format, tone, call to action and hashtags, checked against the platform’s length limits.

Nothing is posted. What you paste is sent to Claude to write the versions and isn’t stored; the answer is kept for 24 hours so the same text costs nothing twice.

How it works

Writer reads your text once and returns a version for each platform you choose: the angle, the format, the text, a call to action and hashtags. Growfinch then checks every part on the server: the platform’s own count, the hashtag number, and no link, @mention, price or date that wasn’t in your text. A part that runs over is written again once, then cut and flagged.

  • Growfinch publishes to Instagram, YouTube Shorts and X today; the LinkedIn, Facebook and Bluesky versions are drafts to copy.
  • X links go in the first reply, as Growfinch posts them. Instagram captions carry no link: use the link in bio.
  • Your text is sent to Claude (Anthropic) to write the versions, and isn’t stored. See the privacy notice.
