PostSiete
One idea in → seven platforms out
On the Free plan, add your own Anthropic key to get AI-written drafts (your key, your cost — usually cents). Get one at console.anthropic.com → API Keys. It's encrypted at rest and never shown again. Pro users don't need this — AI is included.
Save up to 7 brands or clients — each with its own defaults and voice. Pick one in the composer and every draft is written for that brand.
Paste 3–5 of your best posts below, separated by a blank line. AI-generated drafts will be written in that voice instead of generic AI copy — or let AI learn your voice from them automatically.
PostSiete publishes the draft's current text at this time — keep editing until then. Times are your local timezone.
Paste the four keys from your (free) X developer app — step-by-step guide in docs/X_PUBLISHING.md. Your app must have Read and Write permission. Keys are encrypted at rest.
