Nothing to paste? — an indie team's v2.4 launch note: a 19.4s-to-6.8s benchmark, a price drop with a date, one link, a dry and blunt author voice, and an "Excited to share" opener the linter catches before the model strips it. Or , rendered from a saved reply with no run and no charge.
Paste the strongest native version
The original post, the launch note, the changelog. Keep the numbers and the link in. The linter weighs it against each platform's limit in your browser, free, no sign-in.
Say how you write and who reads it
Voice notes or a sample post keep LinkedIn from sanding your edges off. The audience, the allowed link and the thread call change the answer, and the verdict says so.
Read what changed before you paste
Every version under its limit, none of them identical, each adaptation decision explained — and anything the model could not settle handed back as a decision, not padded over.
Does it post to X, LinkedIn, Threads or Bluesky for me?
No. Nothing is published on your behalf and the app holds no platform credentials. Each version has a Copy button, and a link that opens that platform's own web composer - prefilled with the post text on X, Threads and Bluesky. LinkedIn has no documented text prefill, so that link copies the version to your clipboard and opens the LinkedIn composer for you to paste into. You always press post yourself.
What are the character limits it counts against?
X 280 per post with every URL counted as 23 characters regardless of its real length, LinkedIn 3,000, Threads 500 per post and Bluesky 300 per post. The counter under each version recounts as you edit it and turns red with the exact overage when a version busts its limit.
Can I edit a version before posting it?
Yes. Every version is an editable box, not a read-only block. The character counter recounts on each keystroke, the output linter re-checks the edited text for banned patterns and hashtags, and the copy buttons, the downloads and the composer links all carry your edits.
Will it write the same post four times?
No - never posting identical copy across platforms is the first rule of the source skill it is derived from. Each version is derived from the source rather than cut down from the LinkedIn one, and the output linter flags any two versions that come back identical.
Does it invent facts, links or hashtags to fill space?
No. Every claim, number, date, price and URL in every version has to come from the source, the voice notes or the context you supplied. Anything a version needs but the source does not carry comes back as an angle-bracket placeholder and a decision under Before you post, rather than as plausible-sounding filler.
Is any of it free?
The linter is. Source length against every platform limit, the banned engagement-bait patterns, hashtag and multi-link warnings all run in your browser with no sign-in and nothing leaving the page. The adaptation itself calls a model and is charged per run, with the reserve shown before you press the button.
