PostSiete
PostSiete
One idea in, a native draft for each of seven platforms out, written in each client's own voice and previewed exactly as it will post.
Your client approves them from one link, with no login. Siete covers up to 7 client brands for $39 a month, flat.
Start free — no card See what your client sees
Give each client a brand workspace and paste in a few of their best posts. PostSiete learns how that client writes, rhythm and quirks included, and drafts in their voice instead of generic AI copy.
Send the client one link for each idea's drafts. They read every draft, approve it or ask for changes, and can add a note; you see the answer next to the drafts. Approval links come with Siete.
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.
Seven writing tools that live inside the composers you already use, on five sites. X's real weighted character count — where every URL costs 23 and every emoji costs 2. LinkedIn's "…more" fold and Instagram's 125-character cutoff, drawn while you type. A thread splitter that counts the numbering before it splits. Plus readability, a last-line check, and an alt-text nudge.
And one thing it refuses to do: it never posts for you. It never fills a composer, never clicks anything, never touches your accounts. It reads. That is the design, and it is enforced by tests.
Add to Chrome — free → No account, no trial, no card. Works on its own.Or try them in the browser first, no install: X character counter, thread splitter, every platform's limits — all the free tools.
| 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 | 3–5 | |
| 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.
Buffer charges per channel, Later per social set and Planable per workspace, so the bill grows as you sign clients. Siete is one flat price for up to 7 client brands.

Assumes about 2 minutes to review and approve a PostSiete draft instead of writing it from scratch. Every input above is yours to change, starting with what you pay for tools today. PostSiete Pro is $12 flat; PostSiete Siete is $39 flat for several brand workspaces, and the calculator switches to that price once you run more brands than Pro includes. The exact ceiling is the one in the table above. No user earnings are claimed here; the math is yours.
Paste a client's best posts and the AI learns how they write — tone, rhythm, quirks — then every draft for that client sounds like them, not generic AI. It works the same for your own brand.
Every package moves from draft to approved to published, with an approval email written for you. On Siete, your client approves from a link with no login.
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.
On Pro and Siete, Claude writes every draft, up to the monthly numbers in the price table. On Free, the built-in engine arranges your own words for each platform, unless you add your own Anthropic key.
Drafts and client approval cover all seven platforms. Scheduled publishing covers five: X, Threads, Facebook, Instagram and LinkedIn, each connected with keys from your own developer account on that platform. Or post any draft yourself, straight from the studio.
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.
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.
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.
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.
Free: templates arrange your own words for each platform. For AI on Free, add a key from your own Anthropic account (Anthropic makes Claude and bills you for it directly). Pro and Siete include the AI, up to the monthly numbers above.
Drafts and client approval cover all seven platforms. Scheduled publishing covers five: X, Threads, Facebook, Instagram and LinkedIn, each connected with keys from your own developer account on that platform (what that takes). Or post any draft yourself, straight from the studio.
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.
One dashboard with real metrics from every network you connect. Today the stats come from X only.
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.
