One video in, five native posts out
Each platform gets its own cut, size, caption and hook — made for how people actually watch there. No more resizing the same video five times.

Post with your AI.
Tell ChatGPT or Claude what to post. Postwith fits it to Instagram, TikTok, YouTube, Facebook and Pinterest, posts it when you say so — and tells you what worked.
- Everything happens in your chat
- Nothing posts without your OK
- Official sign-in, no shared passwords
Product demo, all inside your AI chat (ChatGPT, Claude or another). You attach a video and ask it to post everywhere tomorrow at 9am. A Postwith card shows five versions — an Instagram Reel, a TikTok, a YouTube Short, a Facebook post and a Pinterest Pin — each opening with a different hook. You choose who can see the TikTok, tap Post once, and all five go live at 9:00 in your audience's time zone. Three days later you ask how they did: question-style hooks held viewers 2.1 times longer, and your AI drafts the next post the same way.

Features
Post with confidence.
Five native versions from one video, posted when you say so — on time, once, and only through official sign-in.
Posts when you say so
Your AI shows each version right in the chat; one tap posts it. Prefer hands-free? Let it post your finished posts on its own.
On your audience's clock
Schedule once. Every post goes out when your audience is awake.
Never posts twice
If a platform hiccups, Postwith checks what actually happened before it tries again.
Official sign-in only
You connect each account with the platform's own login. No bots, no browser tricks, no shared passwords.
Results
Post with data.
Ask how your posts did and get a straight answer — with the numbers to back it up. Your AI uses the same results to make the next post better.
- Answers first. "Question hooks held viewers 2.1× longer" — then the chart, if you want it.
- Honest numbers. Every insight says how many posts it's based on and how fresh the data is.
- No inflated totals. Each platform counts views its own way, so we never add them up.
- A loop, not a report. Your AI drafts the next post from what worked — ready when you are.

For builders
Post with the API.
Everything your AI can do, you can automate: a hosted MCP server, a CLI and a REST API, with the same approvals and audit trail.
- MCP server for ChatGPT, Claude, Cursor and Codex
- CLI for local files, scripts and CI
- REST API with idempotent writes
- Scoped tokens. Your AI never sees platform passwords

My AI could write my posts. It couldn't tell me which ones worked.
So I'm building Postwith: your AI posts everywhere, Postwith measures honestly, and the lesson comes straight back as your next draft. The first 300 founding members build it with me.

FAQ
Questions, answered.
Something else? Write to hello@postwith.app — the founder reads every message.
When do founding members get access?
As soon as each platform approves Postwith, starting with Instagram and Facebook — founding members get in first, platform by platform. There's no fixed date yet: each platform reviews new apps on its own schedule. Until TikTok finishes reviewing Postwith, TikTok posts can only be private — that's TikTok's rule.
You can get a full refund anytime until 14 days after you get access. No questions asked.
What do I need to use it?
A ChatGPT or Claude account that can add connectors, and the social accounts you want to post to. Connect your accounts once at postwith.app, add Postwith to your AI, and you're set. Which ChatGPT and Claude plans support connectors varies — we'll list them at launch, and if yours can't add Postwith, you get a full refund.
Prefer clicking to chatting? The Postwith web app does everything too.
Do I need to open Postwith to post?
No. After the one-time setup, everything happens in your chat: your AI shows you each version, and one tap posts it. The web app is there for your calendar and results whenever you want them.
Will it ever post without me?
Only if you let it. By default your AI shows you exactly what will go out and posts when you say so. You can let it post your finished posts automatically on Instagram, Facebook, YouTube and Pinterest.
TikTok always asks first: its rules require a preview and your own choice of who can see each post. That happens in the chat too.
How does Postwith get into my accounts?
Through each platform's official sign-in. You approve exactly what Postwith can do and can disconnect anytime. We never see your passwords, never use bots or browser automation, and your tokens are encrypted and never shared with your AI or anyone else. See the privacy policy and data deletion pages.
Which networks, and when?
Instagram (professional accounts), Facebook Pages, TikTok, YouTube and Pinterest — each one opens as its official API approval lands. More networks come once these five are excellent.
How is this different from Buffer, Later or Postiz?
They're good at getting posts out, and some connect to AI tools too. Postwith is built around what happens next: honest results, clear lessons, and a next draft that's better because of them.
What do the results tell me?
Where and when each version went out, then — once there's enough comparable data — which hooks, formats and lengths worked best for your audience, with how many posts each insight is based on and how fresh the data is. When there isn't enough data yet, it says so.
Your next post is one message away.
