How it works

From idea to published in 3 steps

Stop overthinking. Start creating.

01
Step 1

Write with AI

Open the editor and describe what you want to say. The AI helps you shape it into a post worth sharing — instantly. No more staring at a blank screen wondering where to start.

02
Step 2

Compose your thread

Write single posts or multi-post threads in a post-style editor — you see exactly how they'll appear as you type. Per-post character counter included.

03
Step 3

Schedule to Threads & X

Pick your time, queue your content, and let Poststash handle the publishing. Post consistently without being glued to your phone.

FAQ

Got questions?

No. Most scheduling tools solve the wrong problem — you still have to know what to write before you open them. Poststash has an AI writing assistant built into the editor that helps you get from blank screen to draft in seconds. The scheduling is just one part of the workflow.

When you open the Write page, you get an AI chat panel alongside your editor. Describe your idea, ask it to rewrite a draft, sharpen the hook, or make it shorter — and it responds in context. It doesn't give you generic content; it helps you shape your own ideas into posts worth sharing.

Yes. The thread composer lets you write multi-post threads with a live preview and per-post character counter. You see exactly how each post in the thread will look before you publish or schedule it. Threads (the platform) and X both support multi-post threads.

You can write and publish to Threads and X (Twitter). LinkedIn support is coming soon. Poststash is built Threads-first — we think it's the most underserved platform for creators right now — but publishing to X at the same time costs you nothing extra.

Poststash is free to join right now. No credit card needed. If we introduce paid plans in the future, all early users will be notified in advance and grandfathered at better terms.
