PostSiete
One idea goes in. Seven drafts come out — a LinkedIn essay, a 280-character post, a timed TikTok script — each written for its platform, never pasted across it. Preview each exactly as it'll post, in your own voice, then publish from the same desk.
Every draft rendered exactly as it posts — LinkedIn's "see more" fold, X's 280, Instagram's caption cutoff, the image crop per platform. Catch what breaks before you publish, not after.
Paste a few of your best posts and the AI learns how you actually write — rhythm, quirks, phrasing — then every draft comes out in your voice. Not generic AI copy.
Drop a blog post, newsletter, or transcript. Get platform-native drafts, then plan them across your content calendar in a single click. Write once; schedule the week.
| Platform | What we write | Hard limit | Hashtags |
|---|---|---|---|
| Hook-first essay, short paragraphs, question close | 3,000 | 3–5 | |
| X (Twitter) | One sharp idea, hook in six words | 280 | 0–2 |
| Visual-first caption, line breaks for rhythm | 2,200 | 5–10 | |
| TikTok | Timed script: hook → proof → payoff → CTA | 2,200 | 3–6 |
| Threads | Conversational, like a smart friend | 500 | 0–2 |
| Warm, shareable, comment-inviting | 63,206 | 1–3 | |
| YouTube Shorts | Sub-60s script with a suggested title | 5,000 | 2–4 |
Character meters run live while you edit. A draft over its limit cannot sneak past you.
| What you're weighing | Per-channel schedulers | X-first creator tools | PostSiete |
|---|---|---|---|
| Monthly cost, 7 platforms | $28–35 (Buffer at $5/channel) → $199 (Hootsuite) | $19–65, mostly one platform | $12 flat. Or $0, self-hosted |
| Writes platform-native drafts | Caption assistant, higher tiers | X only (Hypefury: none) | Yes — 7 platforms, every plan |
| See it exactly as it'll post (native previews) | Enterprise tiers | X-style only | Yes — all 7 platforms, fold & crop accurate |
| AI voice trained on your own posts | Higher plans | — | Built in — paste posts, it learns your voice |
| Approval workflow | Enterprise tiers | — | Built in — draft → approved → published on every plan; shareable client links on Siete |
| API for automation | Varies, often gated | Typefully yes · Hypefury no | Yes — REST on Pro & Siete, n8n export on every plan |
| Who holds your keys & data | They do | They do | You do — your server, your AI key, encrypted at rest |
Their AI is the upsell — ours is your own key at API cost. That's a margin they can't follow us to.
Assumes ~2 minutes to review & approve a PostSiete draft instead of writing from scratch — edit any input above. Reference prices, July 2026 list: Buffer $5/channel (7 channels ≈ $35), Hootsuite Standard $199/user, X-first creator tools $19–65. PostSiete Pro $12 flat. No user earnings are claimed here — the math is yours.
Bring your Anthropic key and every package is written by a frontier model, per-platform. Without a key, a capable built-in engine takes over.
Connect once, publish from the draft card, keep the permalink. Credentials encrypted with AES-256-GCM.
A real editorial workflow with an approval email composed for every package. Agencies start here.
Every account carries a token; programmatic generation runs on Pro and Siete. One-click n8n workflow export on every plan, plus an MCP server so Claude itself can drive the studio.
Full PWA — add it to your home screen from any browser, on any device. An Android build from the same codebase is on the roadmap below.
One Node process. No web framework, no build step — TypeScript runs straight off the source. Files by default, Postgres when you want it. Run it on a $5 VPS or our cloud; either way it's your machine.
See every draft exactly as it'll appear — LinkedIn's "see more" fold, X's 280 counter, Instagram's caption cutoff, the image crop per platform — before you post a word.
Drop a blog post, newsletter, or transcript and get platform-native drafts, then spread them across your calendar in a click. Repurpose, don't retype.
Paste your best posts and the AI learns your voice — tone, rhythm, quirks — then writes every draft to sound like you, not generic AI.
Drafts written in any of sixteen output languages, right-to-left included. The desk itself speaks five — studio, emails and legal pages all arrive in your language.
Beyond the seven social platforms, every package can carry a long-form SEO article up to 7,000 characters — the source the social drafts point back to.
Publish any package to a public showcase link, export it as Markdown or an n8n workflow, and earn free months when the people you send here subscribe.
Every plan can preview and plan all seven platforms on the content calendar. Direct publishing & analytics run natively on X today (the platform we post to directly); the auto-scheduler (Siete) turns X drafts into real scheduled posts. Native publishing & analytics for Instagram, LinkedIn, TikTok and the rest are on the public roadmap.
The monthly AI-draft numbers are fair-use ceilings on our key — generous, and stated so you never have to guess. Past them PostSiete keeps working on its built-in template engine, and connecting your own API key removes the ceiling entirely.
The web app is already a full PWA, so the Android build wraps what is live rather than reimplementing it — one package id, one signing key, and every web deploy reaches installed phones on the next launch. Packaging and Play review are the work that remains. There is nothing to download yet.
Direct scheduled posting to Instagram, LinkedIn, TikTok, Facebook, Threads and YouTube — beyond today's X. Each needs that platform's API approval, so it lands progressively.
One dashboard pulling real metrics from every connected network, not just X. Ships alongside each platform integration above.
Invite teammates into a workspace and put your own brand on client-approval pages.
These are future — not included in today's price, and never billed as if they were.
